    Abstract: Parties established the Mitigation Work Programme (MWP) at COP26 to ”urgently scale up mitigation ambition and implementation” to help reach the temperature goal of the Paris Agreement. At COP27, Parties further fleshed out the MWP, which will be operationalised each year between 2023-2026 via at least two global dialogues, other dialogues and investment-focused events. This paper outlines key questions that could shape the aims, scope, focus, format, and participation in the dialogues, as well as the possible interplay between the MWP global dialogues and investment-focused events by drawing on experiences with other processes and events inside and outside the UNFCCC. This paper also provides lessons from examples in three sub-sectors where mitigation actions have been rapidly scaled up. This paper highlights several open questions related to the substance, process, and timing of the global dialogues and the investment-focused events, as well as potential linkages between these. The paper also discusses possible implications of different choices on these open questions. Decisions on the scope, format, and aims of the MWP dialogues will influence their impacts and the relevance of these dialogues to different countries and stakeholders. Yet, dialogues and events under the MWP will face trade-offs between concentrating on short- versus longer-term issues and outcomes and on choosing a broad or narrow focus. Such choices will impact how many countries the event or dialogue is relevant to. In addition, there are various ongoing initiatives and events outside the UNFCCC that are relevant to the aims of the MWP and that the MWP could usefully learn from. Careful mapping and co-ordination are needed to ensure that the MWP builds on, rather than duplicates, existing initiatives and events within and beyond the UNFCCC.

    Abstract: This paper investigates the potential role and contribution of carbon pricing in transforming emission pathways towards net zero GHG emissions. It reviews carbon pricing’s impacts, overall and in the electricity sector in selected jurisdictions to date. The paper also analyses the current and potential application of emissions pricing (e.g. emissions trading schemes or carbon taxes) in food systems. The analysis finds that carbon pricing could contribute to net zero pathways alongside other policies, yet price levels and coverage to date have been too low to reduce emissions in line with the Paris Agreement’s goals. Carbon pricing’s contribution to net zero pathways could be further strengthened, including by incentivising demand-side shifts, sequencing policies and enhancing international carbon pricing collaboration. Applying emissions pricing in food systems faces significant short-term technical, methodological, and political barriers and could have just transition implications but reducing emissions from food systems could also lead to many co-benefits.

    Abstract: “Authorisation” is a new but as yet undefined component of the guidance for implementation of Article 6 of the Paris Agreement. Authorisation is important as it triggers both corresponding adjustments and reporting requirements. This paper identifies and analyses open questions related to what is authorised, by what process, for what purpose, the format and timing of authorisation, and how any ex-post changes to authorisation can be made. The answers to these questions can affect the attractiveness for Parties and the private sector to participate in Article 6 cooperation. The paper also outlines areas of Article 6.2 guidance that could be usefully clarified at the international level, and implications of different options for the domestic implementation of Article 6 authorisation provisions, drawing from examples of a few frontrunner Parties who have already established bilateral agreements and domestic structures for international cooperation under Article 6. The paper concludes that some of the open questions could be clarified at the international level, such as how to report any changes to authorisations and if the authorisation needs to be provided concurrently by the participating Parties. Other questions could be clarified at the national level by the participating Parties providing the authorisation. These include whether participating Parties can choose to include additional elements in their authorisations, and which roles authorised entities could play.

    Abstract: This paper assesses the role of carbon pricing in a sustainable recovery from COVID-19. It tracks the policy changes in carbon pricing within OECD and G20 countries between January 2020 and August 2021 of the COVID-19 pandemic. Carbon pricing as defined here includes emissions trading schemes, fossil fuel support and carbon, fuel excise or aviation taxes. The paper also highlights the need for the recovery to be sustainable and discusses the advantages, limitations and uses of carbon pricing therein. In addition, it describes additional challenges to as well as increased rationale for carbon pricing in the pandemic. It provides evidence on the effects of carbon pricing on the challenges and discusses carbon pricing design elements to help overcome those challenges. The paper concludes that there were more policy changes with an expected negative impact on climate. However, it is likely that the impact of the climate-positive changes – which are broader in coverage and scope - will outweigh the climate-negative changes.

    Abstract: Greenhouse gas (GHG) mitigation actions will need to be accelerated and scaled up at both national and sub-national levels in order to meet the temperature goals of the Paris Agreement. National governments can play an important role in enabling GHG mitigation actions by non-Party stakeholders (NPS), and in enhancing the interaction between national policies and NPS actions. This paper explores actions national governments could take to facilitate NPS mitigation action in two sub-sectors with large mitigation potential and where NPS play a key role in the successful implementation of mitigation activities. These sectors are renewable electricity generation and procurement in cities and Reducing Emissions from Deforestation and forest Degradation in sub-national jurisdictions. This paper outlines some institutional, regulatory, financial and technical barriers faced by NPS in implementing GHG mitigation activities in these sub-sectors and highlights some examples of national policies and measures that have allowed specific NPS to overcome these barriers. The paper also showcases examples of enabling policy frameworks at the national level that could encourage the replication of such mitigation actions by NPS. An important, common element for successful replication of mitigation activities is for national governments to facilitate co-ordination with NPS; to improve consistency between national and sub-national policies; to identify and clarify responsibilities between different actors; and to regularly review and potentially revise national policies that may unintentionally create barriers to NPS mitigation actions.

    Abstract: This paper assesses quantitative estimates based on economic modelling studies of the economic and environmental benefits from different forms of international co-ordination on carbon pricing. Forms of international co-ordination include: harmonising carbon prices (e.g. through linking carbon markets), extending the coverage of pricing schemes, phasing out fossil fuel subsidies, developing international sectoral agreements, and establishing co-ordination mechanisms to mitigate carbon leakage. All forms of international co-operation on carbon pricing can deliver benefits, both economic (e.g. lower mitigation costs) and/or environmental (e.g. reducing GHG emissions and carbon leakage). Benefits tend to be higher with broader participation of countries, broader coverage of emissions and sectors and more ambitious policy goals. Most, but not all, countries gain economic benefits from international co-operation, and these benefits vary significantly across countries and regions. Complementary measures outside co-operation on carbon pricing (e.g. technology transfers) could ensure that co-operation provides economic benefits for all countries.

    Abstract: This paper identifies and analyses options for the design of the Article 6.4 mechanism in two key areas. These are the possible transition of eligible activities registered under the Kyoto Protocol’s Clean Development Mechanism (CDM) to the Article 6.4 mechanism; and the registration of new activities under the Article 6.4 mechanism. The paper outlines possible transition options and potential implications for four issues relating to host Party approval of activities and to the use, review and revision of baseline methodologies and accreditation standards. The paper also highlights the steps needed to register new or transitioned activities under the Article 6.4 mechanism, and how co-ordination between different actors can facilitate a transition. The paper concludes that there are options available to ensure that the Article 6.4 mechanism can be implemented within a few years of a formal agreement on the rules, modalities and procedures for Article 6, and can build on the significant experience gained with the CDM. The paper highlights different ways that this CDM experience can be built on, and outlines the varying administrative and environmental implications of doing so.

    Abstract: Global materials use is expected to grow in the coming decades in the absence of new policies, bearing substantial negative impacts for the environment. This report analyses the mechanisms through which resource efficiency and circular economy policies can achieve a decoupling between economic growth and material use. Using the OECD’s ENV-Linkages model, the report examines the economic and environmental impacts of a global material fiscal reform, which implements taxes on primary metal and mineral resources, and uses the revenue of these taxes to finance subsidies to recycled goods and to secondary metal production.

    Abstract: Reporting and review requirements under the Paris Agreement include provisions under Article 13 relating to the implementation and achievement of Parties’ Nationally Determined Contributions (NDCs). Draft texts relating to Article 6.2 relating to Parties’ use of cooperative approaches also include provisions on reporting and review. This document identifies and analyses issues related to the interplay of relevant reporting and review requirements under both Article 13 and Article 6 of the Paris Agreement, as it is important to improve complementarity and ensure consistency between the two sets of reporting and review provisions, as well as to meet the already-agreed principles governing transparency. Regarding reporting, the document highlights options for improving the clarity of the provisions concerning the timing, content, and frequency of the three required types of information under Article 6.2 guidance (i.e., the initial report, annual information, and regular information). Regarding Internationally Transferred Mitigation Outcomes (ITMOs), this document highlights several issues relating to timing and vintages that would need to be addressed to facilitate ITMO reporting and review implementation. Regarding review provisions, this document finds that draft A6.2 guidance could usefully provide further detail on some substantive aspects of the Article 6 review process, such as, e.g., clarifying roles of the Party, the TER team, and the secretariat in the review process.

    Abstract: Resource efficiency and circular economy policies aim at reducing resource intensity and use throughout the economy, thereby decreasing environmental impacts. Besides the environmental benefits expected from these policies, potential employment benefits are often emphasised, which would follow the anticipated structural changes in the economy from material-intensive to more labour-intensive activities. However, the size of the employment effect is still unclear and difficult to quantify. To date, the quantitative literature on the employment impacts of the circular economy is still scarce. This study is the first of its kind to review the available studies on this increasingly important policy issue.

    Abstract: This paper examines the consequences of a policy-driven transition towards a more resource-efficient and circular economy on employment levels across countries and sectors during the period 2018-2040. The analysis relies on simulations with ENV-Linkages, the global structural computable general equilibrium model of the OECD Environment Directorate. The results suggest that the overall reallocation of jobs due to a fiscal policy package promoting resource efficiency and the transition to a circular economy is limited to 18 million jobs in 2040 and net job creations are marginal, with 1.8 million of jobs.

    Abstract: Common Tabular Formats (CTFs) for the reporting of information necessary to track progress towards Nationally Determined Contributions (NDCs) under Article 4 of the Paris Agreement, including on the use of cooperative approaches, are to be adopted by COP26. This paper explores concrete examples and worked examples for the structured summary of information to track progress, including on information on cooperative approaches. This paper finds that the structured summary would be more likely to meet the principles established in the Paris Agreement and related decisions, including the Modalities, Procedures and Guidelines (MPGs), if it was separated into CTFs for reporting on tracking progress indicators and a CTF for reporting on the use of cooperative approaches.

    Abstract: This paper provides decision-makers with a framework for prioritising different economic, social and environmental goals and analysing the options available to achieve them. To this end, it develops three stylised COVID-19 recovery pathways (“Rebound”, “Decoupling” and “Wider well-being”) that differ in the extent to which they encompass greenhouse gas (GHG) emission reductions and the integration of mitigation and wider well-being outcomes or, broadly equivalently, SDGs. A number of real-world examples of COVID-19 recovery measures in the surface transport and residential sectors were identified, and the paper maps these measures onto these three stylised pathways. The paper finds a wide divergence in the environmental and social impacts of COVID-19 recovery measures developed to date, with several countries putting in place measures that correspond to all three pathways. The nature and pace of economic recovery in different countries and in aggregate will have important implications for existing, updated and new Nationally Determined Contributions (NDCs) under the Paris Agreement, and the paper also highlights the possible impact of the COVID-19 recovery measures being put in place on NDCs– including on the ambition of both current and future NDCs. The paper concludes that it will be important for governments to improve their understanding of the impact of their recovery measures across multiple policy dimensions (economic, social, environmental) as well as across different time periods (short and long-term) and spatial scales.

    Abstract: Different options of methodological approaches for setting emission baselines are currently under consideration in the international climate negotiations. This paper examines options for baseline approaches for the Article 6.4 mechanism, and draws lessons from how baselines have been used for other market mechanisms. The paper highlights that the different approaches being discussed offer advantages and disadvantages in the context of Article 6.4. Moreover, the paper points out that a one size- fits-all approach to setting baselines is unlikely to be appropriate for the new mechanism, given the variety of possible mitigation activity types and contexts. In particular, analysis of Clean Development Mechanism projects shows that a single baseline approach led to wide variations in baseline levels, implying the need to revise some methodologies if they are to be applied to Article 6.4. The paper also discusses benefits and implications for host Parties participating in the Article 6.4 mechanism, which may affect how Parties achieve their NDCs.

    Abstract: This paper reviews ex-post empirical assessments on the impact of carbon pricing on competitiveness in OECD and G20 countries in the electricity and industrial sectors. Most of these assessments find no statistically significant effects of carbon pricing or energy prices on different dimensions of competitiveness, including net imports, foreign direct investments, turnover, value added, employment, profits, productivity, and innovation. When statistically significant results have been found, the magnitude of such effects tends to be small - either positive or negative. Thus, concerns about negative short-term effects of carbon pricing on firms’ or sectors’ international competitiveness have not come to pass, at least to date. These findings are in part because carbon price levels have been low and because of exemptions to carbon taxes for industry, or generous levels of free allowances to firms covered by emissions trading schemes.

    Abstract: The Modalities, Procedures and Guidelines (MPGs) adopted at COP24 in Katowice lay out rules for reporting and reviewing information under the Enhanced Transparency Framework of the Paris Agreement. The Katowice decision on the MPGs requests the Subsidiary Body for Scientific and Technological Advice (SBSTA) to develop Common Tabular Formats (CTFs) for the reporting of information on, inter alia, financial support provided, mobilised and received. This paper analyses key issues and options that Parties may wish to consider when developing CTFs for reporting on these elements. The widespread use of CTFs for climate finance reporting could potentially facilitate comparability and aggregation of data and information on financial support in the future. This paper also develops options for CTF tables for the three areas of financial support analysed.

    Abstract: This paper explores the consequences on the labour markets of structural changes induced by decarbonisation policies. These policies are likely going to have consequences on labour-income distribution given i) existing rigidities in the labour markets, and ii) their different impacts on sectors and on job categories. These policies are analysed in a general equilibrium modelling framework, which includes interlinkages between different sectors and regions as well as five different categories of workers.

    Abstract: An enhanced transparency framework is a central component of the Agreement, and will apply to all Parties, with flexibility for developing country Parties that need it in the light of their capacities. This paper examines how such flexibility might be operationalised when reporting information under the future enhanced transparency system for greenhouse gas inventories and for progress towards the mitigation component of NDCs under Article 4. The paper also highlights how improvements over time in reporting of adaptation, and support needed and received could be encouraged. For each individual reporting element in these four areas, the paper identifies possible ways that countries with a range of different capacity levels could provide information for specific elements under the four reporting areas examined in the paper.

    Abstract: An enhanced transparency framework will be a central component of the post-2020 international climate policy regime under the Paris Agreement. This paper explores the issue of transparency of climate finance information in the context of climate finance goals under the United Nations’ Framework Convention on Climate Change (UNFCCC). The transparency framework of the Paris Agreement covers only a subset of climate finance, i.e. finance provided and mobilised by developed countries for developing countries, climate finance provided and mobilised by “other” countries for developing countries, as well as climate finance received by developing countries. This paper focuses on data collection, reporting and review of these elements, and explores how the transparency of information on climate finance provided and mobilised could be improved from current arrangements in order to meet the aims set out in the Paris Agreement.

    Abstract: This report provides an analysis of how climate change damages may affect international trade in the coming decades and how international trade can help limit the costs of climate change. It analyses the impacts of climate change on trade considering both direct effects on infrastructure and transport routes and the indirect economic impacts resulting from changes in endowments and production. A qualitative analysis with a literature review is used to present the direct effects of climate change. The indirect impacts of climate change damages on trade are analysed with the OECD’s ENV-Linkages model, a dynamic computable general equilibrium model with global coverage and sector-specific international trade flows. By building on the analysis in the OECD (2015) report "The Economic Consequences of Climate Change", the modelling analysis presents a plausible scenario of future socioeconomic developments and climate damages, to shed light on the mechanisms at work in explaining how climate change will affect trade.

    Abstract: Discussions relating to the 2018 Facilitative Dialogue (FD2018), mandated under the Paris Agreement, are on-going. These discussions are on the scope, inputs, and modalities of the FD2018 as well as any outputs or outcomes from the FD2018. While the mandate of the FD2018 does not explicitly call for outputs or outcomes, identifying outcomes and outputs ex ante could be useful in focusing discussions and inputs to the facilitative dialogue, as well as in shaping its modalities. The objective of this paper is to highlight the implications of agreeing and identifying specific outputs and outcomes ex ante, and exploring what type of outputs and outcomes would best serve the interests of the FD2018. This document also identifies key questions that could guide decision-making on what modalities would be appropriate for the FD2018; however, identification of options for specific modalities of FD2018 are out of the scope of this paper.

    Abstract: Decision 1/CP.21 adopting the Paris Agreement established a mandate for a facilitative dialogue to be convened among Parties in 2018. This mandate established two main objectives of the 2018 facilitative dialogue (FD2018): to take stock of collective progress made towards long-term climate goals and to inform preparation of nationally determined contributions. Proposal(s) from the COP22 and COP23 presidencies on how the dialogue should be conducted are expected to be made by COP23. This paper “unpacks” the two main objectives of the FD2018 into distinct components, and examines the implications of addressing different components on the information needs of the FD2018. The paper also examines different types of information that could be required for FD2018 and their availability. Finally, the paper looks at other collective review or stocktake processes that have been carried out under the U.N. to identify relevant lessons for the FD2018, particularly regarding inputs and associated outputs.

    Abstract: The Paris Agreement, adopted by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), reinforces the international framework for adaptation action by establishing a global adaptation goal. Under the Paris Agreement, countries have also agreed to an enhanced transparency framework for action, which includes adaptation. The Agreement also requests each Party to submit and update an “adaptation communication” as appropriate. This paper explores what elements of countries’ adaptation responses and progress could be reported under the Paris Agreement so as to better communicate efforts towards enhanced adaptation and resilience. The paper also highlights the potential benefits both at a national and an international level from identifying and collating adaptation-related information. Finally the paper outlines a possible structure of an adaptation communication, and identifies options and associated information needs for the adaptation-related components of the global stocktake agreed to in the Paris Agreement.

    Abstract: Adaptation responses are needed to address the existing levels of climate variability and to prepare for future climate impacts. There is wide agreement that adaptation is an important issue and would benefit from being enhanced through more effective action and better planning. The prominence of adaptation in the UNFCCC negotiations has increased, in part as the scientific evidence has become clearer that climate change is occurring and its impacts are projected to grow in future. Efforts to enhance adaptation actions and increase resilience are thus expected to play a key role in the post-2020 climate agreement to be agreed at COP21 in December 2015. This paper explores how the 2015 agreement can help to foster enhanced policies and co-ordinate planning for greater resilience and adaptation capabilities at the national level. The paper considers the technical advantages and disadvantages of selected adaptation-related concepts that have been put forward in the negotiations. These include proposals for global or national goals; developing or improving adaptation institutions or planning; enhancing information availability; and facilitating or enhancing adaptation finance. Many of these proposals have the potential to improve sub-national, national and international planning about and responses to climate adaptation. However, the actual impact of these proposals is likely to vary significantly depending on how they are implemented on the ground.

    Abstract: Limiting the increase in global average temperature to below 2°C compared to pre-industrial levels will require ambitious mitigation action by a broad range of actors including Parties to the United Nations Framework Convention on Climate Change (UNFCCC), i.e., national governments, and non-party stakeholders (NPS). This paper focuses on three types of NPS, namely, sub-national governments, the private sector and financial institutions, and examines how the 2015 agreement could help the NPS encourage increased mitigation actions as well as the financing for such actions. The paper identifies five barriers that can prevent NPS from enhancing their actions and assesses how the current process under the UNFCCC is addressing these barriers for the pre-2020 period. It also explores options to establish or enhance links between the UNFCCC and NPS in the 2015 agreement for post-2020, in order to further address the barriers and enhance actions by NPS.

    Abstract: This report develops an analytical framework that assesses the macroeconomic, environmental and distributional consequences of energy subsidy reforms. The framework is applied to the case of Indonesia to study the consequences in this country of a gradual phase out of all energy consumption subsidies between 2012 and 2020. The energy subsidy estimates used as inputs to this modelling analysis are those calculated by the International Energy Agency, using a synthetic indicator known as “price gaps”. The analysis relies on simulations made with an extended version of the OECD’s ENV-Linkages model. The phase out of energy consumption subsidies was simulated under three stylised redistribution schemes: direct payment on a per household basis, support to labour incomes, and subsidies on food products. The modelling results in this report indicate that if Indonesia were to remove its fossil fuel and electricity consumption subsidies, it would record real GDP gains of 0.4% to 0.7% in 2020, according to the redistribution scheme envisaged. The redistribution through direct payment on a per household basis performs best in terms of GDP gains. The aggregate gains for consumers in terms of welfare are higher, ranging from 0.8% to 1.6% in 2020. Both GDP and welfare gains arise from a more efficient allocation of resources across sectors resulting from phasing out energy subsidies. Meanwhile, a redistribution scheme through food subsidies tends to create other inefficiencies. The simulations show that the redistribution scheme ultimately matters in determining the overall distributional performance of the reform. Cash transfers, and to a lesser extent food subsidies, can make the reform more attractive for poorer households and reduce poverty. Mechanisms that compensate households via payments proportional to labour income are, on the contrary, more beneficial to higher income households and increase poverty. This is because households with informal labour earnings, which are not eligible for these payments, are more represented among the poor. The analysis also shows that phasing out energy subsidies is projected to reduce Indonesian CO2 emissions from fuel combustion by 10.8% to 12.6% and GHG emissions by 7.9% to 8.3%, in 2020 in the various scenarios, with respect to the baseline. These emission reductions exclude emissions from deforestation, which are large but highly uncertain and for which the model cannot make reliable projections.

    Abstract: Climate support will be an important element in reaching a post-2020 climate agreement at COP 21 in December 2015. To further increase and mobilise the levels of climate support post-2020, a number of proposals have been made in the negotiating text produced in the Geneva session of the Ad-hoc Working Group on the Durban Platform of the UN Framework Convention on Climate Change (UNFCCC) in February 2015. This paper explores the advantages and disadvantages of several of these proposals, focusing on those that are clear and specific. The paper assesses proposals on mobilising climate finance using the following criteria: (i) the level of financial flows that they could generate; (ii) how much of this could be mobilised in the UNFCCC context; (iii) the ease of implementation of the proposal; (iv) if and how such increased mobilisation could be monitored; and (v) whether the proposal would fill a specific gap in the context of climate support within the UNFCCC. The paper undertakes a similar assessment for proposals in the Geneva text on enhancing the level of technology development and transfer, as well as capacity building. It discusses whether the proposals could potentially increase technology development and transfer, capacity building and development, as well as whether they are likely to do so in practice, based on current experience and ease of implementation. The proposals vary significantly in the amount of climate support they could mobilise (or enhance, in the case of technology and capacity building), for a range of reasons. These include the particular wording of the proposals, their sensitivity to national implementation, uncertainty in measuring progress towards objectives, and in some cases the limited role the UNFCCC plays as an institution in a given area of climate support.

    Abstract: There are many reasons why the United Nations Framework Convention on Climate Change (UNFCCC) reporting framework requests information from countries. These include understanding and tracking progress with individual or collective commitments or pledges, providing confidence and enhancing accountability in quantified information measured and reported, and providing background information on the scope and ambition of national climate responses. This paper highlights the gaps, inconsistencies and uncertainties in the current reporting framework, which was developed for both long-standing obligations and mitigation pledges for the period to 2020. The paper also identifies possible improvements in the UNFCCC reporting framework in the context of the post-2020 transparency framework and nationally determined contributions (NDCs) for the post-2020 period.

    Abstract: There is widespread recognition that climate finance needs to be scaled up from its current levels. However, there is no clear view on how developed countries can efficiently and effectively mobilise further climate finance to meet the needs of developing countries. Developed countries have committed to mobilise USD 100 bn per year of climate finance for developing countries by 2020 from a variety of sources. These include both public and private finance, thus the private sector is likely to play a significant role in the mobilisation of climate finance to meet this commitment. This paper explores how scale-up and replication of effective climate finance interventions efficiently mobilise private climate finance. The interventions examined in the paper have already been, or are being, scaled up or replicated. Scaling-up and replication of such climate finance interventions could be an efficient way to increase the private sector’s interest in mobilisation of climate finance, and thus to make progress towards the USD 100 bn per year goal by 2020. The paper draws lessons from selected mitigation and available adaptation case studies at project- and programme-levels as well as from experience with international climate funds. The paper examines three key aspects needed to scale up and replicate climate finance. The first is the institutional structures and decision-making framework of the climate finance source, its aims, the scale at which it operates and how barriers to scaling-up and replication have been addressed. Second, the paper explores how demonstrating effective low-carbon, climate-resilient technologies and systems can facilitate scale-up and replication. Third, the paper discusses the influence of policies to enhance domestic enabling environments for scaling-up and replication.

    Abstract: This document provides a detailed technical description of the ENV-Linkages model. The OECD ENV-Linkages Computable General Equilibrium (CGE) model is an economic model that describes how economic activities are inter-linked across several macroeconomic sectors and regions. It links economic activity to environmental pressure, specifically to emissions of greenhouse gases (GHGs). The links between economic activities and emissions are projected for several decades into the future, and thus shed light on the impacts of environmental policies for the medium- and long-term future. In this paper specific attention is given to the equations that form the core of the model. The version of the model presented here is used for analysis carried out for the OECD Environmental Outlook to 2050 (OECD, 2012). An updated version of the model is expected to play a key role in the new CIRCLE project (OECD, 2013).

    Abstract: Shifting public and private investment from “brown” to “green” is an essential part of climate change. The post-2020 climate agreement to be agreed at COP 21 in December 2015 has the potential to play a significant role in signalling the importance of such a shift. This paper explores how the 2015 agreement could spur further mobilisation of climate finance by examining the current state of play regarding existing financing environments and mechanisms. These include examining the existing international institutional arrangements under the UNFCCC to see how balanced financing, co-ordination, streamlining and complementarity between institutions could be achieved. The paper also highlights the key role that in-country enabling environments can play in further mobilising public and private climate finance, and discusses how the 2015 agreement could enhance both “pull” and “push” factors for mobilisation. In addition, the paper also discusses how the agreement could facilitate the broad use of a spectrum of financial instruments and the further development of an enhanced system for measurement, reporting and verification of climate finance.

    Abstract: This report focuses on the effects of climate change impacts on economic growth. Simulations with the OECD’s dynamic global general equilibrium model ENV-Linkages assess the consequences of a selected number of climate change impacts in the various world regions at the macroeconomic and sectoral level. This is complemented with an assessment of very long-run implications, using the AD-RICE model. The analysis finds that the effect of climate change impacts on annual global GDP is projected to increase over time, leading to a global GDP loss of 0.7% to 2.5% by 2060 for the most likely equilibrium climate sensitivity range. Underlying these annual global GDP losses are much larger sectoral and regional variations. Agricultural impacts dominate in most regions, while damages from sea level rise gradually become more important. Negative economic consequences are especially large in South and South-East Asia whereas other regions will be less affected and, in some cases, benefit thanks to adjustments from international trade. Emissions to 2060 will have important consequences in later decades and centuries. Simulations with the AD-RICE model suggest that if emissions continue to grow after 2060, annual damages of climate change could reach 1.5%-4.8% of GDP by the end of the century. Some impacts and risks from climate change have not been quantified in this study, including extreme weather events, water stress and large-scale disruptions. These will potentially have large economic consequences, and on balance the costs of inaction presented here likely underestimate the full costs of climate change impacts. More research is needed to assess them as well as the various uncertainties and risks involved. However, this should not delay policy action, but rather induce policy frameworks that are able to deal with new information and with the fact that by their nature some uncertainties and risks will never be resolved.

    Abstract: In its 2012 edition of the World Energy Outlook, the International Energy Agency (IEA) produced an Efficient World Scenario (IEA, 2012) to assess how implementing only economically viable energy efficiency measures would affect energy markets, investment and greenhouse emissions (GHG). The IEA analysis found that in order to halve global primary energy demand over 2010-2035, additional investments of USD 11.8 trillion in more efficient end-use technologies would be necessary. Using the OECD ENV-Linkages macro-economic model, this report simulates the economic and environmental impacts which the IEA Efficient World Scenario implies...

    Abstract: At the 16th Conference of the Parties (COP) in 2010, developed countries formalised a collective climate finance commitment made previously in Copenhagen of “mobilising jointly USD 100 billion per year by 2020 to address the needs of developing countries...from a wide variety of sources, public and private, bilateral and multilateral, including alternative sources” (UNFCCC, 2010). However, there is currently no definition of which “climate” activities, flows, or other interventions could count towards the USD 100 billion; what “mobilising” means; or even which countries are covered by this commitment. The paper examines different definitions used by 24 key actors in climate finance to quantify the level of private climate finance mobilised by their interventions, as well as the methods used to track such private climate finance. Key findings are that i) methodologies to assess and estimate mobilisation vary widely, and ii) considerable risk of double-counting exists.

    Abstract: Competitiveness and carbon leakage issues have been some of the main concerns in the implementation and discussions of climate policies. These concerns are particularly important in the presence of multiple carbon markets since differences in climate change policy approaches may have impacts on the relative competitiveness of domestic sectors in countries with more stringent policies, and on the environmental effectiveness through carbon leakage. This paper examines the macroeconomic and sectoral competitiveness and carbon leakage impacts associated with a range of stylised mitigation policy scenarios. The scenarios reflect different depictions of carbon markets in terms of their level of linkages, their coverage (i.e. number of countries participating, types of gases and sectors) and the stringency of the carbon pricing policy across countries. The paper also investigates some policies to address competitiveness and carbon leakage issues. The analysis considers border carbon adjustments (BCAs) as well as direct and indirect (offset-based) linking of carbon markets. The results show that in presence of multiple carbon markets, competitiveness can decrease in countries that undertake climate policies, also leading to carbon leakage. The negative sectoral competitiveness and leakage effects can be reduced when more countries act, more emission sources are covered, and when the climate mitigation policy is harmonised across countries. The results also show that response policies, such as BCAs and linking of carbon markets, can address some, but not all, of the competitiveness and carbon leakage issues. While BCAs are more effective in addressing domestic competitiveness concerns than linking instruments, the latter are better in preserving the welfare of countries that are not undertaking a climate policy.

    Abstract: Ensuring that climate finance is used effectively will help to maximise its impact. The effectiveness of climate finance can be defined as the extent to which an activity attains its stated aims. These aims can vary, depending on the source of climate finance and how it is channelled. There are therefore different views on what “effective” climate finance is, as well as on how this effectiveness can be assessed. This paper explores how different communities view climate finance effectiveness; the policies or institutional pre-conditions that facilitate effectiveness; and how effectiveness is currently monitored and evaluated. The paper concludes by discussing the conflicts and trade-offs encountered in assessing effectiveness and a possible way forward in balancing multiple views and priorities.

    Abstract: Developed countries have committed under the international negotiations to jointly mobilising USD 100 billion per year by 2020 for climate change mitigation and adaptation in developing countries. Yet consistent and comprehensive data to track this commitment are currently lacking. Such data will also help governments and the private sector understand how much and what type of climate finance is flowing today, so as to be able to evaluate progress and effectiveness of international climate finance flows. Estimates based on available data are highly uncertain and incomplete, highlighting several challenges in establishing a robust tracking system. A more political question is what should be the internationally agreed definition of “climate finance” or, absent agreement on that, what types of flows or activities might count towards the USD 100 billion? On the more technical side, challenges include clearly defining flows and sources of international climate finance, determining the cause and effect of flows, and establishing the boundaries of finance flowing towards climate change action. This paper considers what data are currently available to track climate finance, and demonstrates the complex nature of financial flows through examples across international and domestic as well as public and private flows. The examples highlight questions on how to count and track climate finance.

    Abstract: The book presents a major meta-analysis of 'value of a statistical life' (VSL) estimates derived from surveys where people around the world have been asked about their willingness to pay for small reduction in mortality risks. The analysis seeks to explain the differences in the estimates, for example across countries. Differences in incomes and the magintude of the risk reduction people have been asked to value were found to be the factors having the strongest impact on VSL, but a number of other policy-relevant factors are also important. Based on the meta-analysis, and a broad review of the literature, the book also presents clear advice on how VSL values best can be used in assessments of environmental, health and transport policies, such as in cost-benefit analyses. Using explicit VSL estimates to quantify the benefits to society of fatality risk reductions can play an important role in the development of more cost-effective public policies.

    Abstract: The principles of sustainable development play an integral role in making development assistance work at the level of policies, plans and programmes. In response to the Paris Declaration call to “… develop and apply common approaches for ‘Strategic Environmental Assessment’ at sector and national levels” among donors and partners, the Guidance on Applying Strategic Environmental Assessment was endorsed in 2006 by members of the OECD Development Assistance Committee, representatives of developing countries receiving aid, the United Nations Development Programme, the United Nations Environment Programme, the World Bank and many other agencies. Since then, a growing number of countries at all levels of development have legislation or regulations prescribing the application of Strategic Environmental Assessment (SEA)  and many more are introducing it as part of their policy tools. This is creating unique opportunities for better policy making and planning by incorporating environmental considerations into high-level decision-making and opening new mechanisms to build consensus on development priorities within governments themselves and between governments and societies. Many development co-operation agencies and their partners are already making good progress in applying SEA. This publication presents the nine most interesting case studies of SEA in progress, selected from a total 100. These nine cases highlight that SEA can:• Safeguard environmental assets for sustainable poverty reduction and development;• Build public engagement in decision making;• Prevent costly mistakes by alerting decision-makers to potentially unsustainable development options at an early stage in the decision-making process;• Speed up implementation of projects and programmes;• Facilitate co-operation around shared environmental resources and contribute to conflict prevention.

    Abstract: The provision of water supply, sanitation and wastewater services generates substantial benefits for public health, the economy and the environment. Benefit-to-cost ratios can be as high as 7 to 1 for basic water and sanitation services in developing countries. Wastewater treatment interventions, for example, generate significant benefits for public health, the environment and for certain economic sectors such as fisheries, tourism and property markets. The full magnitude of the benefits of water services is seldom considered for a number of reasons, including the difficulty in quantifying important non-economic benefits such as non-use values, dignity, social status, cleanliness and overall well-being. Also, information about the benefits of water services is usually hidden in the technical literature, where it remains invisible to key decision-makers in ministries. This report draws together and summarises existing information on the benefits of water and sanitation.

    Abstract: This document describes economic baseline projections to 2050 for several world regions. It describes how socio-economic drivers are used to create a consistent projection of economic activity for the coming decades, applying the general framework of “conditional convergence”. This economic baseline is created using the ENV-Linkages model version 3. This baseline is used for modelling analysis with the ENVLinkages model as carried out for the OECD Environmental Outlook to 2050 (to be released in Spring 2012). Specific attention is given in this paper to projections for the energy system as part of the economy, to allow detailed links between economic activity and environmental pressures, including emissions of greenhouse gases (GHGs).

    Abstract: The Cancun Agreements outlined the list of topics to be included in biennial reports and indicated that guidelines for them were to be developed, but provided limited guidance on their structure and content. This paper proposes a structure for biennial reports for both developed and developing countries under the UNFCCC, and outlines possible reporting formats by which countries could submit this information. The paper suggests that: (i) a similar structure is developed for biennial reports from both developed and developing countries; this would ensure consistency of information presented within different countries’ reports, and would also facilitate international assessment and review (IAR) and international consultations and analysis (ICA); (ii) three main sections are included for biennial reports from all Parties: GHG inventory information; progress on mitigation and mitigation actions; and financial, technology and capacity building support; in addition, a section on emissions projections would be mandatory for developed countries and optional for developing countries; (iii) biennial reports focus on key information where possible, with fuller descriptions and background information reported either in annexes (in the case of national inventory reports from developing countries) or less frequently via other reporting mechanisms under the UNFCCC (such as national communications). This paper also proposes that flexibility be maintained in the reporting guidelines for biennial reports. This could be achieved through the use of “reporting levels” which reflect the different national circumstances and levels of reporting experience between Parties (particularly within the group of developing country Parties). Parties could choose the most appropriate level for each section of their report according to their goal type or reporting capacity, and “move up” levels as and when they can (as is currently the case for GHG inventory calculations). A limited number of levels are suggested for developed countries, as in many cases reporting to the highest level is already mandatory for these countries. For developing countries there could be greater flexibility and a higher number of reporting levels, reflecting the broad range of national circumstances and reporting capacities within this group. The introduction of reporting levels into guidelines would allow countries to provide information at a level that is consistent with their current capabilities, and to improve their reporting over time.

    Abstract: In 2010, the international community took steps to improve the system of reporting and verification under the United Nations Framework Convention on Climate Change (UNFCCC). Parties to the UNFCCC decided at the sixteenth meeting of the Conference of the Parties (COP 16) to enhance reporting for all countries and to conduct “international assessment and review” (IAR) of certain information from developed countries and “international consultations and analysis” (ICA) of biennial update reports from developing countries. This is a step change from the existing reporting and review system – particularly for developing countries, since information from these countries is currently reported on an infrequent basis and is not reviewed. Establishing a system that combines improved reporting with some form of international verification could improve the quality of information available internationally and increase confidence in the integrity of the information reported. This would help to build trust between countries and potentially also increase the level of ambition of mitigation actions. Further decisions need to be made by Parties in order to determine the scope, inputs, process, outputs and frequency of IAR and ICA, as the decisions agreed at COP 16 (known as the “Cancun Agreements”) provide limited guidance on these items. This paper outlines key questions to help guide such decisions and provides suggestions for the possible design and function of IAR and ICA. It outlines how they could build on existing review processes under the UNFCCC and draw on lessons from other multilateral review processes. The challenge for the international community will be to ensure that IAR and ICA are useful processes, both nationally and internationally, while minimising the resource requirements needed to implement them.

    Abstract: This Test Guideline describes an in vitro screen for chemical effects on steroidogenesis, specifically the production of 17ß-estradiol (E2) and testosterone (T). The human H295R adreno-carcinoma cell line, used for the assay, expresses genes that encode for all the key enzymes for steroidogenesis. After an acclimation period of 24 h in multi-well plates, cells are exposed for 48 h to seven concentrations of the test chemical in at least triplicate. Solvent and a known inhibitor and inducer of hormone production are run at a fixed concentration as negative and positive controls. At the end of the exposure period, cell viability in each well is analyzed. Concentrations of hormones in the medium can be measured using a variety of methods including commercially available hormone measurement kits and/or instrumental techniques such as liquid chromatography-mass spectrometry. Data are expressed as fold change relative to the solvent control and the Lowest-Observed-Effect-Concentration. If the assay is negative, the highest concentration tested is reported as the No-Observed-Effect-Concentration.

    Abstract: This report presents the OECD review of Portugal’s environmental policy performance for 2011. It finds that environmental policies have been consolidated and strengthened since the last review in 2001, but that meeting the post-Kyoto targets for reducing greenhouse gas emissions will be challenging. With energy and climate policies being closely related, the report points out that with less than 50% of hydro capacity currently being exploited, there is potential for further development in that area. It also describes the challenges regarding coastal zone and marine management. Topics covered in the report include greening growth, implementation of environmental policies , international co-operation , climate change, waste management and the 3Rs (reduce, reuse, recycle), and nature and biodiversity.

    Abstract: Developing growth strategies that promote greener lifestyles requires a good understanding of what factors affect people’s behaviour towards the environment. Recent OECD work based on periodic surveys of more than 10 000 households across a number of countries and areas represents a breakthrough by providing a common framework to collect unique empirical evidence for better policy design. This publication presents responses from the most recent round of the OECD survey implemented in 2011 in 5 areas (energy, food, transport, waste and water) and 11 countries: Australia, Canada, Chile, France, Israel, Japan, Korea, the Netherlands, Spain, Sweden and Switzerland. Analysis comparing the data across countries, policy conditions and households’ characteristics reveals which measures most effectively change behaviour. Each round of the survey also allows to track changes over time and to explore new emerging issues. The new survey confirms the importance of providing the right economic incentives for influencing our decisions. The findings indicate that “soft” measures such as labelling and public information campaigns also have a significant complementary role to play. Spurring desirable behaviour change requires a mix of these instruments. This book is a milestone for all those interested by the challenging question of ways to promote greener behaviour, from policy makers to individual citizens.

    Abstract: This Test Guideline describes an assay that assesses early life-stage effects and potential adverse consequences of putative endocrine disrupting chemicals (e.g. oestrogens, androgens and steroidogenesis inhibitors) on fish sexual development. In the test, fish are exposed, from newly fertilized egg until the completion of sexual differentiation at about 60 days post hatch, to at least three concentrations of the test substance dissolved in water. In each treatment level and control(s) group(s), a minimum of four replicates is recommended. At termination of the test, two core endpoints are measured in each fish: vitellogenin concentration from head and tail or from blood sampling, and proportion of males, females, intersex and undifferentiated fish through gonadal histology. In fish species possessing a genetic sex marker, the genetic sex is identified to determine sex reversal in individual fish. The combination of the two core endocrine endpoints, vitellogenin concentration and phenotypic (and possibly genotypic) sex ratio, enable the test to indicate the mode of action of the test chemical.

    Abstract: Eco-innovation is more important than ever on the public policy agenda. It is a major driver for green growth and contributes to the environmental performance and economic development of OECD and developing countries alike. This report takes a pragmatic approach to policies that support the development and diffusion of eco-innovation. Building on the OECD Innovation Strategy, it argues that eco-innovation is not merely about technological developments: non-technical innovations matter as well. It acknowledges that policies do not operate in a vacuum and that they must take account of the contexts that influence the development and diffusion of eco-innovation, such as market structures. It explores links between eco-innovation policies and related fields such as industry, competition, and international cooperation. This work builds on an OECD inventory of eco-innovation policies in OECD countries and in China. It also draws on studies of select environment-friendly innovations, highlighting different patterns of development across countries. It also incorporates extensive international consultation on the topics of eco-innovation and green growth. The results from this publication will contribute to the Green Growth Strategy being developed by the OECD as a practical policy package for governments to harness the potential of greener growth.

    Abstract: This Test Guideline describes an acute immobilisation assay on chronomids and is designed to complement existing Test Guidelines for chironomid chronic toxicity assays (TG 218, 219 and 233). The test method is based on TG 202: Daphnia sp. Acute Immobilisation Test. First instar Chironomus sp. larvae are exposed to a range of concentrations of the test substance in water-only vessels for a period of 48 hours. C. riparius is the preferred species but C. dilutus or C. yoshimatsui may also be used for the test. At least 20 larvae, preferably divided into four groups of five larvae each, should be used for each test concentration and for controls. In the definitive test, at least five test concentrations should be used, with a dilution water control and solvent control (if appropriate). Immobilisation is recorded at 24 and 48 hours, and if data allow, the EC50 is calculated at 24 and 48 hours. A limit test with a single concentration may also be performed at 100 mg/L of test substance or up to the practical limit of solubility (whichever is lowest) in order to demonstrate that the EC50 is greater than this concentration.

    Keywords: Environment
    Abstract: This Test Guideline describes an in vivo assay that detects chemicals that may induce gene mutations. In this assay, transgenic rats or mice that contain multiple copies of chromosomally integrated plasmid or phage shuttle vectors are used. The transgenes contain reporter genes for the detection of various types of mutations induced by test substances. A negative control group and a minimum of 3 treatment groups of transgenic animals are treated for 28 consecutive days. Administration is usually followed by a 3-day period of time, prior to sacrifice, during which the agent is not administered and during which unrepaired DNA lesions are fixed into stable mutations. At the end of this 3-day period, the animals are sacrificed, genomic DNA is isolated from the tissue(s) of interest and purified. Mutations that have arisen during treatment are scored by recovering the transgene and analysing the phenotype of the reporter gene in a bacterial host deficient for the reporter gene. Mutant frequency, the reported parameter in these assays,is calculated by dividing the number of plaques/plasmids containing mutations in the transgene by the total number of plaques/plasmids recovered from the same DNA sample.

    Abstract: This Test Guideline is designed to provide an evaluation of reproductive and developmental effects that may occur as a result of pre- and postnatal chemical exposure as well as an evaluation of systemic toxicity in pregnant and lactating females and young and adult offspring. In the assay, sexually-mature males and females rodents (parental (P) generation) are exposed to graduated doses of the test substance starting 2 weeks before mating and continuously through mating, gestation and weaning of their pups (F1 generation). At weaning, pups are selected and assigned to cohorts of animals for reproductive/developmental toxicity testing (cohort 1), developmental neurotoxicity testing (cohort 2) and developmental immunotoxicity testing (cohort 3). The F1 offspring receive further treatment with the test substance from weaning to adulthood. Clinical observations and pathology examinations are performed on all animals for signs of toxicity, with special emphasis on the integrity and performance of the male and female reproductive systems and the health, growth, development and function of the offspring. Part of cohort 1 (cohort 1B) may be extended to include an F2 generation; in this case, procedures for F1 animals will be similar to those for the P animals.

    Abstract: Using a computable general equilibrium, this paper quantifies the GDP and employment effects of an illustrative greenhouse gas emissions reduction policy. The paper first analyses the direct negative economic effects of the emissions restrictions on GDP and examines labour sectoral reallocations in a framework where labour markets are perfectly flexible. The model is then modified to incorporate labour market imperfections in OECD countries that could generate unemployment, namely, short-run rigidities in real wage adjustment. It is shown that imperfect wage adjustment increases the cost of mitigation policy since unemployment increases in the short-run, but that the carbon tax revenue generated can be recycled so as offset some or all of this effect, notably when it is used to reduce wage-taxes. Thus, taking realistic labour market imperfections into account in a CGE model affects the GDP costs of mitigation policy in two ways: first by introducing extra costs due to the increased unemployment that such policy may entail; second by creating the possibility of a double dividend effect when carbon taxes are recycled so as to reduce distorting taxes on labour income..

    Abstract: Undertaken jointly with United Nations Environment Programme, the report analyses policies and issues related to climate change adaptation and mitigation in the tourism sector. It provides policy recommendations, with the objective to identify priority areas to be included in a framework for action in the area of climate change and tourism. A review of the state of policy-making on this important issue clearly indicates that greater efforts could be made by countries to understand the likely impacts of climate change on tourism; there is a low awareness of the tourism sector's climate change mitigation and adaptation needs; and that current policy, with few exceptions, is inadequate to the scale of the challenge, both on mitigation and adaptation.

    Abstract: The purpose of this test is to determine the effects of a substance on the growth of freshwater microalgae and/or cyanobacteria. Exponentially growing test organisms are exposed to the test substance in batch cultures over a period of normally 72 hours. The system response is the reduction of growth in a series of algal cultures exposed to, at least, five concentrations of a test substance. Three replicates at each test concentration should be used. The response is evaluated as a function of the exposure concentration in comparison with the average growth of control cultures. The cultures are allowed unrestricted exponential growth under nutrient sufficient conditions (two alternative growth media: the OECD and the AAP) and continuous fluorescent illumination. Growth and growth inhibition are quantified from measurements of the algal biomass as a function of time. The limit test corresponds to one dose level of 100 mg/L. This study includes: the determination, at least daily, of the algal biomass; the measure of the pH (at the beginning and at the end); microscopic observation. This Test Guideline describes two response variables: average specific growth rate, and yield.

    Abstract: This paper outlines options for new reporting guidelines for national communications from Annex I and non-Annex I countries, both for “full” national communications and biennial “updates”. These reports can facilitate the sharing of information between Parties and may be used to assess the implementation of actions and progress towards the Convention’s objectives. There are significant gaps in the current climate reporting framework. These gaps are particularly marked for non-Annex I countries in terms of GHG emissions and trends, mitigation and adaptation actions. There are also gaps in terms of the effect of mitigation actions and support provided and received for climate-related activities, including for technology transfer and capacity building. This paper suggests that: (i) national communications be produced more frequently while their focus is streamlined; (ii) reporting guidelines be revised to improve transparency about mitigation commitments/actions/targets that countries have indicated to the international community as well as other obligations taken under the UNFCCC and subsequently; (iii) standard reporting formats be used for more of the information in national communications; (iv) a flexible reporting framework be established for non-Annex I countries, where the information in (and possibly timing of) national reports is “tiered” according to national circumstances; (v) an increased emphasis be placed on reporting of “key” issues; (vi) information routinely provided on adaptation measures and policies be formalised; (vii) reporting on “support” be increased and its structure improved; and (viii) in reports from non-Annex I countries, the provision of information that is already routinely provided be formalised.

    Abstract: Emissions trading systems (ETS) can play a major role in a cost-effective climate policy framework. Both direct linking of ETSs and indirect linking through a common crediting mechanism can reduce costs of action. We use a global recursive-dynamic computable general equilibrium model to assess the effects of direct and indirect linking of ETS systems across world regions. Linking of domestic Annex I ETSs leads to moderate aggregate cost savings, as differences in domestic permit prices are limited. However, the economy of the main seller, Russia, is negatively affected by the real exchange rate appreciation that is induced by the large export of permits. The cost-saving potential for developed countries of well-functioning crediting mechanisms appears to be very large. Even limited use of credits would nearly halve mitigation costs; cost savings would be largest for carbon-intensive economies. However, one open issue is whether these gains can be fully reaped in reality, given that direct linking and the use of crediting mechanisms both raise complex system design and implementation issues. The analysis in this paper shows, however, that the potential gains to be reaped are so large, that substantial efforts in this domain are warranted.

    Abstract: Information and communication technologies (ICTs) are a key enabler of “green growth” in all sectors of the economy. They are a key part of government strategies for a sustainable economic recovery. This report looks at how ICTs can improve their own environmental performance, and how they can be used to improve environmental performance throughout the economy and society. Direct environmental impacts of ICTs are considerable in areas such as energy use, materials throughput and end-of-life treatment. Government “green ICT” policies can be instrumental in promoting life-cycle approaches for improved R&D and design of ICT goods, services and systems. Innovative ICT applications enable sustainable production and consumption across the entire economy. The potential for improving environmental performance targets specific products, but also entire systems and industry sectors, e.g. construction, transport, energy.

    Keywords: Energy ; Environment
    Abstract: The UN Framework Convention on Climate Change (UNFCCC) and its Kyoto Protocol established reporting requirements for Parties. This has resulted in comprehensive and timely information on national greenhouse gas (GHG) emissions from Annex I Parties, periodic reporting of other information from Annex I Parties and irregular provision of GHG emissions and other information from non-Annex I Parties. Thus, the current reporting framework does not enable a complete or up-to-date assessment of current global GHG emissions, goals, projected future emission trends or mitigation actions and their effects. This paper explores options for the functions, form, timing and content of future national reports under the UNFCCC, focusing on national communications. It suggests that reporting guidelines for future national communications could be “tiered”. This could allow countries to produce national communication “updates” on a frequent (e.g. biennial) basis – focusing the information in these updates on information of most relevance to the international community. “Full” national communications would also continue to be produced, but less frequently than “updates”. Different tiers could be established according to the type of country (e.g. Annex I or non-Annex I); type of mitigation pledge (e.g. nation-wide emissions limit, sectoral goal, mitigation action); and/or the frequency with which changes in particular parameters occur. Such a tiered approach could also provide flexibility for countries to improve the content and frequency of information that they report as their capacities allow. “Updates” to national communications, containing more targeted information on key elements, could be more user-friendly and could focus on the core elements in which national and international users are interested. Streamlined “updates” to national communications could therefore focus on parameters that either change frequently and/or are not currently reported or systematically included in national communications or other climate reports under the UNFCCC. This includes: regular information on historical GHG emissions (including calculation methodology and transfers of units) for many countries, as well as on financial support from Annex I countries; short or medium-term mitigation goals and strategies (e.g. to 2020); progress in implementing such goals and strategies; and improved information on financial needs in terms of GHG mitigation and adaptation activities (by non-Annex I countries).

    Abstract: The chemicals industry - including industrial chemicals, pharmaceuticals, pesticides, food and feed additives and cosmetics - is one of the world’s largest industrial sectors. Many chemical products are traded internationally. Varying national requirements can mean duplication of efforts and significant costs for the chemicals industry, as well as posing barriers to trade. By agreeing on test methods and data quality and sharing the workload of chemical safety testing and assessments, countries together achieve environmentally sustainable and cost-effective results. For non-clinical health and safety testing, for example, the results of such studies carried out on a chemical product in one OECD country must be accepted by the others as long as it was carried out in accordance with the OECD Test Guidelines and Principles of Good Laboratory Practice. This saves the chemicals industry the expense of duplicative testing for products that are marketed in more than one country. This report analyses the rigorous and comprehensive system for assessing and managing chemicals that helps governments and industry save about EUR 150 million each year, through “work sharing” facilitated by the OECD.

    Abstract: The Local Lymph Node Assay: DA (LLNA: DA) is a non-radioactive modification to the LLNA method for identifying potential skin sensitizing test substances and measuring the proliferation of lymphocytes they induce in the auricular lymph nodes. The method, described in mouse (CBA/J strain), is based on measurement of the adenosine triphosphate (ATP) content by bioluminescence as an indicator of this proliferation. A minimum of four animals is used per dose group, with a minimum of three concentrations of the test substance, plus a concurrent negative control group and, if appropriate, a positive control group. The experimental schedule is during 8 days. The time from animal sacrifice to measurement of ATP should not exceed 30 min. The procedure from excision of lymph nodes to ATP measurement should be kept uniform for each animal and completed within 20 minutes. The luciferin/luciferase method is applied to measure the bioluminescence in Relative Luminescence Units (RLU). This study includes: measurements (weighing, RLU), and clinical daily observations. The results are expressed as the Stimulation Index (SI) obtained by calculation. The SI should be ¡Ý1.8 before further evaluation of the test material as a potential skin sensitizer is warranted.

    Abstract: This Test Guideline describes procedures designed to estimate the acute oral toxicity of substances to birds, and it provides three testing options: (1) limit dose test, (2) LD50-slope test, and (3) LD50-only test. The LD50-slope and LD50-only options are sequential testing procedures. The test method selected will depend on whether or not a definitive median dose (LD50) and slope of the dose-response curve are both needed. The limit dose test is the preferred test when toxicity is expected to be low and lethality is unlikely at the limit dose. The limit dose should be adequate for assessment purposes, and it is usually 2000 mg/kg-bwt. Five or ten birds are tested at the limit dose in addition to a control group. The LD50-slope test is the preferred test when regulatory or other requirements determine that the slope of the dose-response curve and/or the confidence interval is required in addition to an estimate of the LD50. This is a 3- or 4-stage test with 24 or 34 birds in addition to a control group. The LD50-only test is the preferred test when regulatory or other requirements determine that only the median lethal dose is required but neither the slope of the dose response curve or the confidence interval for the LD50 is required. This may be the appropriate test to estimate a percentile of a species sensitivity distribution of LD50s and to provide information for product labelling purposes. This test has two stages, with 14 birds in addition to a control group. Software to be used with TG 223. Click here. Software not part of the Mutual Acceptance of Data.

    Abstract: The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that are unable to migrate to the poles during the anaphase stage of cell division. The assay detects the activity of clastogenic and aneugenic test substances in cells that have undergone cell division during or after exposure to the test substance. This Test Guideline allows the use of protocols with and without the actin polymerisation inhibitor cytochalasin B. Cytochalasin B allows for the identification and selective analysis of micronucleus frequency in cells that have completed one mitosis, because such cells are binucleate. This Test Guideline also allows the use of protocols without cytokinesis block provided there is evidence that the cell population analysed has undergone mitosis.

    Keywords: Environment
    Abstract: This Test Guideline is designed to assess the effects of a substance on micro-organisms from activated sludge of waste-water treatment plants by measuring their respiration rate (carbon and/or ammonium oxidation) as oxygen consumption. The test results may also serve as an indicator of suitable non-inhibitory concentrations of test substances to be used in biodegradability tests. The test allows the determination of ECx and/or NOEC values of the test substance. The inhibition of three different oxygen uptakes may be determined, i.e. total, heterotrophic only, and that due to nitrification in the absence and presence of N-allylthiourea, a specific nitrification inhibitor. For obtaining both NOEC and ECx, six controls and five treatment concentrations in a geometric series with five replicates are recommended. In each test vessel, test mixtures containing water, synthetic sewage feed and the test substance are incubated at the pH of 7.5 ±0.5 and the temperature within 20±2°C under forced aeration to keep the dissolved oxygen concentration above 60-70% saturation. The oxygen consumption is measured after 3 hours of exposure and additional measurements at 30 minutes of exposure can be performed in the case that the test substance is rapidly degraded.

    Keywords: Environment
    Abstract: The basic principle underlying the Local Lymph Node Assay (LLNA) in mouse is that sensitizers induce a primary proliferation of lymphocytes in the auricular lymph nodes draining the site of chemical application. This proliferation is proportional to the dose applied and provides a measurement of sensitisation. The method described is based on the use of radioactive labelling to measure cell proliferation. A minimum of four animals is used per dose group, with a minimum of three concentrations of the test substance, plus a negative control group treated with the vehicle only, and a positive control, as appropriate. The experimental schedule of the assay is during 6 days. Thereafter, the animals are killed and a cell suspension of lymph node cells is prepared. The incorporation of 3H-methyl thymidine is measured by ¦Â-scintillation counting as disintegrations per minute (DPM). The Test Guideline includes performance standards that can be used to evaluate the validation status of new and/or modified test methods that are functionally and mechanistically similar to the LLNA. A reduced LLNA approach which could use up to 40% fewer animals is also described as an option. This study includes: measurements (weighing, DPM), and clinical daily observations. Results are expressed as the Stimulation Index (SI).The SI is obtained by calculation and should be ¡Ý3 before classification of the test material as a skin sensitizer is warranted.

    Abstract: The Local Lymph Node Assay: BrdU-ELISA (LLNA:BrdU-ELISA) is a non-radioactive modification to the LLNA method for identifying potential skin sensitizing test substances and measuring the proliferation of lymphocytes they induce in the auricular lymph nodes. The method described in mouse is based on the use of measuring 5-bromo-2-deoxyuridine (BrdU) content, an analogue of thymidine, as an indicator of this proliferation. A minimum of four animals is used per dose group, with a minimum of three concentrations of the test substance, plus a concurrent negative control group and a positive control group. The experimental schedule is during 6 days. Thereafter, the animals are killed and a single cell suspension of lymph node cells (LNC) is prepared. The procedure for preparing the LNC is crucial, in particular for the small lymph nodes in NC animals. Then the BrdU content in DNA of lymphocytes is measured by ELISA using a commercial kit of by Flow Cytometry (FCM). This study includes: measurements (weighing, BrdU) and clinical daily observations. The results are expressed as the Stimulation Index (SI) obtained by calculation from the mean BrdU labelling index. The SI should be ≥1.6 for the ELISA method or ≥2.7 for the FCM method for identifying the test material as a potential skin sensitizer.

    Abstract: This Guideline is designed to assess the effects of prolonged exposure of chemicals to the life-cycle of the sediment-dwelling freshwater dipteran Chironomus sp. First instar chironomid larvae are exposed to five concentrations of the test chemical in sediment-water systems. The test substance is spiked into the water or alternatively the sediment, and first instar larvae are subsequently introduced into test beakers in which the sediment and water concentrations have been stabilised. Chironomid emergence, time to emergence, and sex ratio of the fully emerged and alive midges are assessed. Emerged adults are transferred to breeding cages, to facilitate swarming, mating and oviposition. The number of egg ropes produced and their fertility are assessed. From these egg ropes, first instar larvae of the 2nd generation are obtained. These larvae are placed into freshly prepared test beakers (spiking procedure as for the 1st generation) to determine the viability of the 2nd generation through an assessment of their emergence, time to emergence and the sex ratio of the fully emerged and alive midges. All data are analysed either by a regression model to estimate the concentration that would cause X% reduction in the relevant endpoint, or by using hypothesis testing to determine a No Observed Effect Concentration (NOEC).

    Abstract: This Test Guideline describes in vivo studies that provide information on mass balance, absorption, bioavailability, tissue distribution, metabolism, excretion, and basic toxicokinetic parameters [e.g. AUC], as well as supplemental approaches that may provide useful information on toxicokinetics. Information from toxicokinetic studies helps to relate concentration or dose to the observed toxicity and to understand its mechanism of toxicity. The test substance ("unlabelled" or "radiolabelled" forms) is normally administered by an oral route, but other routes of administration may be applicable. Single dose administration of the substance (preferably a minimum of two dose levels) may be adequate, but repeated dose may be needed in some circumstances. Toxicokinetic studies should preferably be carried out in the same species as that used in other toxicological studies performed with the substance (normally the rat, a minimum of 4 animals of one sex for each dose). Initial estimation of absorption can be achieved by mass balance determination, but further investigations such as intravenous (IV) administration and biliary excretion studies might be necessary. Bioavailability can be determined from plasma/blood kinetics of oral and IV groups. The percent of the total dose in tissues should at a minimum be measured at the termination of experiment,but additional time points may also be needed. Metabolites present at 5 % or greater of the administered dose should be identified. The rate and extent of excretion of the administered dose should be determined by measuring the percent recovered dose from urine, faeces and expired air.

    Keywords: Environment
    Abstract: This Test Guideline describes procedures designed to assess bioaccumulation of chemicals in soil oligochaetes. The parameters which characterise the bioaccumulation of a substance include the bioaccumulation factor (BAF), the uptake rate constant (ks) and the elimination rate constant (ke). The test consists of two phases: the uptake (exposure) phase and the elimination (post-exposure) phase. An elimination phase is always required unless uptake of the test substance during the exposure phase has been insignificant. The test organisms are exposed to the test substance during the uptake phase. The test substance is incorporated into the soil; it is recommended to use the artificial soil described in the OECD Test Guideline 207 (Earthworm, acute toxicity test). The uptake phase should be of 14 days (enchytraeids) or 21 days (earthworms) unless it is demonstrated that steady state has been reached. For the elimination phase, the worms are transferred to a soil free of test substance. The elimination phase is generally of 21 days.

    Abstract: Solving the world’s environmental problems could take a significant toll on economic growth if only today’s technologies are available. We know that innovation – the creation and adoption of new cleaner technologies and know-how – provides a means to achieve local and global environmental goals at significantly lower costs. Innovation is also a major driver of economic growth. OECD governments are increasingly using environmentally related taxes because they are typically one of the most effective policy tools available. Exploring the relationship between environmentally related taxation and innovation is critical to understanding the full impacts of this policy instrument as well as one potential facet of “green growth.” By putting a price on pollution, do environmentally related taxes spur innovation? What types of innovation result? Does the design of the tax play a critical role? What is the effect of this innovation? In analysing these questions, this report draws on case studies that cover Japan, Korea, Spain, Sweden, Switzerland, the United Kingdom, Israel and others. It covers a wide set of environmental issues and technologies, as well as the economic and policy contexts. The research methods range from econometric analysis to interviews with business owners and executives. The report also explores the use of environmentally related taxes in OECD countries and outlines considerations for policymakers when implementing these taxes. Green growth policies can stimulate economic growth while preventing environmental degradation, biodiversity loss and unsustainable natural resource use. The results from this publication will contribute to the Green Growth Strategy being developed by the OECD as a practical policy package for governments to harness the potential of greener growth.

    Abstract: As the hubs of economic activity, cities drive the vast majority of the world’s energy use and are major contributors to global greenhouse gas emissions. Because they are home to major infrastructure and highly concentrated populations, cities are also vulnerable to the impacts of climate change, such as rising sea levels, warmer temperatures and fiercer storms. At the same time, better urban planning and policies can reduce energy use and greenhouse gas emissions and improve the resilience of urban infrastructure to climate change, thus shaping future trends. This book shows how city and metropolitan regional governments working in tandem with national governments can change the way we think about responding to climate change. The chapters analyse: trends in urbanisation, economic growth, energy use and climate change; the economic benefits of climate action; the role of urban policies in reducing energy demand, improving resilience to climate change and complementing global climate policies; frameworks for multilevel governance of climate change including engagement with relevant stakeholders; and the contribution of cities to “green growth”, including the “greening” of fiscal policies, innovation and jobs. The book also explores policy tools and best practices from both OECD and some non-member countries. Cities and Climate Change reveals the importance of addressing climate change across all levels of government. Local involvement through “climate-conscious” urban planning and management can help achieve national climate goals and minimise tradeoffs between environmental and economic priorities at local levels. The book will be relevant to policy makers, researchers, and others with an interest in learning more about urbanisation and climate change policy.

    Series Statement: OECD Environment Working Papers no.13
    Keywords: Environment
    Abstract: Debates exist between those who claim that environmental policy will impose additional burdens and costs on industries, thus impairing their competitiveness, and those who claim that improved environmental performance can spur competitiveness. These arguments often surface when new environmental policy regulation are considered, e.g. when the REACH Directive was introduced in Europe, or when a government is considering the introduction of a carbon tax. The report develops a conceptual framework to shed some light on this difficult debate. Competitiveness impacts of environmental policies may derive from the policy itself, or from the improvements of the environmental performance that derives from the policy. These impacts can be analysed at either firm or industry levels; they may differ over the short and long term. Globalisation, with the increasing role of MNEs and mobile capital and labour, is adding more complexity. This framework is used to decipher some of the messages that come out of empirical studies on these issues. Empirical evidence is mixed, and the paper identifies methodological and substantive reasons why empirical research fails to determine the relationship between environmental policy and competitiveness. Lessons derive from this literature review. Typically, even when implementing the environmental policy is clearly in the overall interest of society, the costs and benefits of the policy are unlikely to be equally shared among economic agents. While some win, individual firms or industries may stand to lose. Policy design should make sure that the adverse competitiveness impacts are not unnecessarily large, for example by paying attention to predictability, transition periods, and transaction costs. Specific measures to support the losers in their adjustment can also be developed. Sometimes measures to mitigate the adverse competitiveness impacts of an environmental policy are necessary to achieve political support for the policy. In those instances, the planned measures should be carefully analysed from several angles to ensure that they do not inadvertently hurt the efficiency and effectiveness of the original policy. More work is required to further explore these issues, which are consequential for the design, the implementation and the enforcement of environmental policies.

    Abstract: Eco-innovation will be a key driver of industry efforts to tackle climate change and realise “green growth” in the post-Kyoto era. Eco-innovation calls for faster introduction of breakthrough technologies and for more systemic application of available solutions, including non-technological ones. It also offers opportunities to involve new players, develop new industries and increase competitiveness. Structural change in economies will be imperative in coming decades. This book presents the research and analysis carried out during the first phase of the OECD Project on Sustainable Manufacturing and Eco-innovation. Its aim is to provide benchmarking tools on sustainable manufacturing and to spur eco-innovation through better understanding of innovation mechanisms. It reviews the concepts and forms an analytical framework; analyses the nature and processes of eco-innovation; discusses existing sustainable manufacturing indicators; examines methodologies for measuring eco-innovation; and takes stock of national strategies and policy initiatives for eco-innovation.

    Abstract: This 2010 review of Japan's environmental conditions and policies evaluates progress in reducing the pollution burden, improving natural resource management, integrating environmental and economic policies, and strengthening international co-operation. It includes coverage of policy for greening growth, implementation of environmental policies, climate change, waste management and the 3Rs (reduce, reuse, recycle), and nature and biodiversity. The review finds that since the last review, Japan has made steady progress in addressing a range of environmental issues, notably air and water pollution, and the management of chemicals and waste. The energy intensity of the economy has continued to decrease, particularly in the industrial sector, and is among the lowest in OECD countries. Material intensity has also decreased. At the same time, several more complex, long-term challenges have come to the fore: climate change, sound waste, materials management, and biodiversity conservation. Much of the last decade was characterised by sluggish economic growth, and environment and green innovation are targeted as key drivers of future growth and job creation in Japan's New Growth Strategy.

    Abstract: El cambio climático es una amenaza seria y a largo plazo que puede afectar a cualquier parte del mundo. Su impacto negativo golpeará a los países pobres y a las capas de población más desfavorecidas de manera desproporcionada, complicando aún más el logro de sus objetivos de desarrollo. La guía Integración de la Adaptación en la Cooperación para el Desarrollo ofrece información esencial y consejos sobre cómo facilitar la integración de la adaptación al cambio climático en los procesos de desarrollo. Los objetivos de esta guía son los siguientes: i) facilitar la comprensión de las implicaciones del cambio climático en la práctica del desarrollo y promover la necesidad asociada de integrar la adaptación al cambio climático en las políticas y prácticas de desarrollo tanto de los organismos de cooperación como de los países socios, ii) identificar los enfoques más adecuados para integrar la adaptación al cambio climático en las políticas de desarrollo a nivel nacional, sectorial y de proyecto, tanto en zonas urbanas como en zonas rurales, y iii) determinar modalidades prácticas para que los donantes apoyen a los países socios en sus esfuerzos para reducir su vulnerabilidad a la variabilidad climática y el cambio climático. Aunque los esfuerzos por integrar la adaptación al cambio climático ha de ser dirigido por los países socios, los donantes internacionales tienen un papel crítico que desempeñar en el apoyo a esos esfuerzos. Esta guía para la orientación de políticas está destinada especialmente a responsables políticos, a profesionales de organismos de cooperación al desarrollo y sus contrapartes en los gobiernos de los países, y a otras partes interesadas, tales como organizaciones no gubernamentales.

    Abstract: Companies are increasingly aware of the need to address climate change. However, while many companies are taking action to address climate change, many others are still lagging behind. This report surveys responsible business practices addressing climate change and driving the shift to a low-carbon economy. It summarises policies, regulations and other instruments in support of a low carbon economy in OECD countries and emerging economies, and analyses corporate responses to these drivers. Using the principles of responsible business conduct identified in the OECD Guidelines for Multinational Enterprises, this report reviews three key areas of corporate action: accounting for greenhouse gas emissions; achieving emissions reductions; and engaging suppliers, consumers and other stakeholders.

    Abstract: This Test Guideline describes an in vitro procedure that may be used for the hazard identification of irritant chemicals (substances and mixtures) in accordance with the UN Globally Harmonized System of Classification and Labelling (GHS) Category 2. It is based on reconstructed human epidermis (RhE), which in its overall design closely mimics the biochemical and physiological properties of the upper parts of the human skin. Cell viability is measured by enzymatic conversion of the vital dye MTT into a blue formazan salt that is quantitatively measured after extraction from tissues. Irritant test substances are identified by their ability to decrease cell viability below defined threshold levels (below or equal to 50% for UN GHS Category 2). This Test Guideline also includes a set of Performance Standards for the assessment of similar and modified RhE-based test methods. There are three validated test methods that adhere to this Test Guideline. Depending on the regulatory framework and the classification system in use, this procedure may be used to determine the skin irritancy of test substances as a stand-alone replacement test for in vivo skin irritation testing, or as a partial replacement test, within a tiered testing strategy.

    Abstract: Biodiversity and ecosystem services provide tangible benefits for society, such as food provisioning, water purification, genetic resources or climate regulation. These services provide critical life support functions and contribute to human health, well being and economic growth. Yet biodiversity is declining worldwide and, in some areas, this loss is accelerating. The need for policies that promote the conservation and sustainable use of biodiversity and ecosystem services is more important than ever. Payments for Ecosystem Services (PES) is a direct and flexible incentive-based mechanism under which the user or beneficiary of an ecosystem service makes a direct payment to an individual or community whose land use decisions have an impact on the ecosystem service provision. Interest in PES has been increasing rapidly over the past decade: PES are proliferating worldwide and there are already more than 300 programmes in place today at national, regional and local levels. Drawing on the literature concerning effective PES and on more than 30 case studies from both developed and developing countries, this book aims to identify good practice in the design and implementation of PES programmes so as to enhance their environmental and cost effectiveness. It addresses the following questions: Why are PES useful and how do they work? How can they be made most effective environmentally and how can their cost-effectiveness be maximised? What are the different potential sources of finance for PES programmes, and how can they be secured? and What are the lessons learned from existing PES programmes and insights for future programmes, including international PES?

    Abstract: The Bali Action Plan (BAP) language on “measurable, reportable and verifiable” (MRV) greenhouse gas mitigation actions and commitments for a post-2012 climate framework was introduced to apply both to developed countries’ greenhouse gas (GHG) commitments and actions (paragraph 1(b)(i) of the BAP), as well as to “nationally appropriate mitigation actions by developing country Parties in the context of sustainable development, supported and enabled by technology, financing and capacity-building” (paragraph 1(b)(ii)). This paper provides an overview of current efforts to assess if GHG mitigation actions underway in different countries and regions are “measurable, reportable and verifiable”. The paper also assesses how such efforts could be improved, explores MRV options for different types of GHG mitigation actions, and highlights decision points needed to establish a post-2012 framework.Several different types of GHG mitigation actions and commitments have been proposed for the post-2012 period. Some of these - such as national-level GHG emission limits - are already being used, with countries therefore already gaining experience with implementing, monitoring, reporting (and potentially reviewing or verifying the effects of) such actions/commitments. The extent of this experience varies both by type of action/commitment, as well as by country and sector. In general, Annex I countries have significant experience with monitoring and reporting national emission levels (reflecting their reporting commitments under the UNFCCC and Kyoto Protocol). However, official reporting on other GHG-mitigation actions occurs every few years in Annex I countries and only irregularly in non-Annex I countries. Thus, significant new guidance would be needed if post-2012 MRV provisions were to focus on GHG mitigation actions rather than GHG emission levels. In deciding a MRV framework, it will be important to consider measurement, reporting and verification issues separately (as for example some non-supported actions may be reported but not verified). A transition process may also be needed for some countries, in terms of what is to be subject to MRV provisions, and how M, R and V are to be carried out.

    Abstract: Water is vital for human and economic development, and for maintaining ecosystems. However, billions of people lack access to water and sanitation services, mainly due to poor governance and inadequate investment and maintenance. The situation is becoming more urgent due to increasing pressure, competition and even conflict over the use of water resources. The OECD has been working for many years to address these challenges. The results of recent work are summarised in Managing Water for All: An OECD Perspective on Pricing and Financing, which emphasises the economic and financial aspects of water resources management and water service provision, the need for an integrated approach (including governance considerations) to address these complex policy challenges, and the importance of establishing a firm evidence base to support policy development and implementation. The report examines: strategic financial planning for water supply and sanitation that balances the key sources of revenues for the water sector – the“3Ts” of taxes, tariffs and transfers; the design and implementation of water pricing strategies that balance financial sustainability with other policy objectives; recent developments in private sector participation in the water sector; and trends and the future outlook of water use in agriculture. It considers both developing and OECD countries and offers concrete recommendations and checklists for action. The report is an invaluable resource for policy makers, academics, NGOs and all others interested in the challenges facing the water sector today. The key messages for policy makers are summarised in this volume.

    Abstract: Sectoral approaches are proposed as a means to broaden the global scope of greenhouse gas (GHG) mitigation to developing countries. Market mechanisms are put forward in that context to create incentives for mitigation in developing countries beyond the existing Clean Development Mechanism (CDM), and to encourage mitigation at least possible cost. The introduction of new, sector-based, market mechanisms is only one of many proposals discussed by UNFCCC Parties in the context of a post-2012 international climate policy framework, as a possible means to support mitigation actions in developing countries. This paper considers the carbon market aspects of sectoral approaches to reduce greenhouse gas (GHG) emissions in developing countries. It discusses three general ways to link sectoral goals with the carbon market: (i) intensity goals, based on a GHG performance per unit of output; (ii) fixed emission goals, with an ex-post issuance of credits or trading with an ex-ante allocation of allowances; and (iii) technology-based sectoral objectives. This paper explores the domestic policy implications of moving from a single project approach (i.e., CDM), to a multi-plant, sector-wide carbon market mechanism implied by sectoral crediting and trading. It also touches on possible transition issues, especially from intensity-based emission goals to fixed ones. The paper concludes that sector-based market mechanisms, regardless of the design option chosen, will require some significant upfront effort both nationally and internationally to set appropriate baselines and ensure adequate measurement, reporting and verification in order to generate economically valuable and environmentally-credible credits. Technology diffusion goals may be supported by other means than the carbon market if developing GHG baselines for such activities were too difficult. Sectoral approaches also imply some significant policy effort in countries that adhere to them, to ensure that the baselines are exceeded so that carbon market revenues are generated, and that these revenues represent effective incentives for entities to pursue GHG mitigation, wherever it is most cost-effective to do so.

    Abstract: This Test Guideline describes an amphibian metamorphosis assay intended to screen substances which may interfere with the normal functioning of the hypothalamo-pituitary-thyroid axis. The assay was validated with the species Xenopus laevis, which is recommended for use in the Guideline. The assay uses three test chemical concentrations and the necessary controls, including a carrier control if necessary. The assay starts with tadpoles at the development stage 51 on the Nieuwkoop and Faber scale and is extended for a duration of 21 days. Four replicate test vessels are used for each treatment level and control(s). After 7 days of exposure, a sub-set of tadpoles from each treatment level is sampled for the measurement of the length of the hind-limb. At termination of 21-day exposure period, developmental stage, snout-to-vent length and hind limb length are measured on all remaining tadpoles. A sub-set of tadpoles from each treatment level is fixed (whole-body or dissected) for histopathology of the thyroid gland.

    Keywords: Environment
    Abstract: This Test Guideline describes the modified MITI test (II). This test permits the measurement of the Biochemical Oxygen Demand (BOD) and the analysis of residual chemicals in order to evaluate the inherent biodegradability of chemical substances which have been found by the Standard MITI Method (I) to be low degradable. An automated closed-system oxygen consumption measuring apparatus (BOD-meter) is used. Chemicals to be tested are inoculated in the testing vessels (six bottles with different quantities of test chemical) with micro-organisms. In order to check the activity of the inoculum, the use of control substances (aniline, sodium acetate or sodium benzoate) is desirable. During the test period, the BOD is measured continuously. Biodegradability is calculated on the basis of BOD and supplemental chemical analysis, such as measurement of the dissolved organic carbon concentration, concentration of residual chemicals, etc. The BOD curve is obtained continuously and automatically for 14 to 28 days. After the 14 to 28 days of testing, pH, residual chemicals and intermediates in the testing vessels are analysed.

    Abstract: The objective of these chronic toxicity studies is to characterize the profile of a substance in a mammalian species (primarily rodents) following prolonged and repeated exposure. The Test Guideline focuses on rodents and oral administration. Both sexes should be used. For rodents, at least 20 animals per sex per group should normally be used at each dose level, while for non-rodents a minimum of 4 per sex per group is recommended. At least three dose levels should be used in addition to the concurrent control group. Frequency of exposure normally is daily, but may vary according to the route chosen (oral, dermal or inhalation) and should be adjusted according to the toxicokinetic profile of the test substance. The duration of the exposure period should be 12 months. The study report should include: measurements (weighing) and regular detailed observations (haematological examination, urinalysis, clinical chemistry), as well as necropsy procedures and histopathology.

    Abstract: The Bali Action Plan (BAP) indicated the importance of “measurable, reportable and verifiable” (MRV) greenhouse gas (GHG) mitigation actions and commitments, as well as support for GHG mitigation actions, in the post-2012 climate framework. Negotiations underway for this framework have highlighted the benefits of, and interest in, expanding current MRV-related provisions, including to develop a more comprehensive and timely picture of countries’ mitigation efforts and support. Establishing some form of reporting or recording mechanism that could be used to centralise and track information on country mitigation actions, commitments and support could fill this gap. This mechanism could focus on current efforts, or also include information on future or planned efforts. Such a mechanism could take different forms, including a stand-alone electronic registry where actions (and potentially also commitments and support) could be reported ex post. Alternatively, information on actions and commitments could be recorded ex ante as an integral appendix of a post-2012 climate agreement. This paper explores the possible purposes, coverage and form of such a reporting/recording mechanism (subsequently referred to as a NAMAs registry); what information it could include in terms of actions, commitments and support; and the institutional implications of different design options. It thus focuses on the measurable and reportable components of MRV, rather than on verification.

    Abstract: This method provides information on health hazard likely to arise from short-term exposure to a test article (gas, vapour or aerosol/particulate test article) by inhalation. The revised Test Guideline describes two studies: a traditional LC50 protocol and a Concentration x Time (C x t) protocol. It can be used to estimate a median lethal concentration (LC50), non-lethal threshold concentration (LC01) and slope, and to identify possible sex susceptibility. This Test Guideline enables a test article quantitative risk assessment and classification according to the Globally Harmonized System for the Classification and Labelling of Chemicals. In the traditional LC50 protocol, animals are exposed to one limit concentration or to three concentrations, at least, for a predetermined duration, generally of 4 hours. Usually 10 animals should be used for each concentration. In the C x T protocol, animals are exposed to one limit concentration or a series of concentrations over multiple time durations. Usually 2 animals per C x t interval are used. Animals (the preferred species is the rat) should be observed for at least 14 days. The study includes measurements (including weighing), daily and detailed observations, as well as gross necropsy.

    Abstract: The objective of a long-term carcinogenicity study is to observe test animals for a major portion of their life span for the development of neoplastic lesions during or after exposure to various doses of a test substance by an appropriate route of administration. This Test Guideline is intended primarily for use with rats and mice, and for oral administration. Both sexes should be used. Each dose group and concurrent control group should contain at least 50 animals of each sex. At least three dose levels and a concurrent control should be used. Animals are dosed with the test substance daily (oral, dermal or inhalation administration) and the mode of exposure should be adjusted according to the toxicokinetic profile of the test substance. The duration of the study will normally be 24 months for rodents. For specific strains of mice, duration of 18 months may be more appropriate. Termination of the study should be considered when the number of survivors in the lower dose groups or the control group falls below 25 per cent. The results of these studies include: measurements (weighing, food consumption), and, at least, daily and detailed observations, as well as gross necropsy and histopathology.

    Abstract: The Hershberger Bioassay is an in vivo short–term screening test. It evaluates the ability of a chemical to elicit biological activities consistent with androgen agonists, antagonists or 5 á-reductase inhibitors. The current bioassay is based on the changes in weight of five androgen-dependent tissues in the castrate-peripubertal male rat: the ventral prostate, seminal vesicle (plus fluids and coagulating glands), levator ani-bulbocavernosus muscle, paired Cowper’s glands and the glans penis. In order to establish whether a test substance can have androgenic or antiandrogenic action, two – respectively three - dose groups of the test substance, plus positive and vehicle (negative) controls are normally sufficient. The test substance is administered by gavage or subcutaneous injection daily for 10 consecutive days. To test for antiandrogens, the test substance is administered together with a reference androgen agonist. Each treated and control group should include a minimum of 6 animals. The animals are necropsied approximately 24 hours after the last administration of the test substance. The tissues are excised and their fresh weights determined. A statistically significant increase (androgenic) or decrease (antiandrogenic) in the weights of two of the five tissues indicates a positive response in this assay.
