    Parallel Title: Erscheint auch als Print Version: Foster, Vivien Understanding Drivers of Decoupling of Global Transport CO2 Emissions from Economic Growth: Evidence from 145 Countries

    Abstract: This paper examines the extent to which countries have succeeded in decoupling transport emissions from economic growth, and how changes in emissions intensity, economic growth, and population growth have contributed to changes in transportation-related emissions. The paper employs a modified version of the Tapio decoupling model, and demonstrates that over the 1990-2018 study period only 12 of 145 countries achieved "absolute decoupling," defined as reducing emissions while growing gross domestic product. The majority of the top emitters remain in a "relative decoupling" state, with emissions growing more slowly than gross domestic product. Many of the middle- and low-income countries have not achieved decoupling; their emissions are growing as fast as or faster than gross domestic product. To understand the driving factors of transport-related carbon emissions, the paper conducts index-decomposition and an econometric analysis. The results reveal that while transportation emission intensity has declined in most countries, economic growth and population growth have offset these declines. If these patterns continue, achieving the goals of the Paris Agreement with improvements in efficiency alone seems unrealistic. The paper also shows evidence that higher energy prices are associated with strong emissions reduction

    Parallel Title: Erscheint auch als Deichmann, Uwe Relationship between Energy Intensity and Economic Growth: New Evidence from a Multi-Country Multi-Sector Data Set
    Keywords: 1990 - 2014 ; Energiekonsum ; Wirtschaftswachstum ; Welt ; Graue Literatur
    Abstract: This paper revisits the relationship between energy intensity and economic growth, using a flexible piecewise linear regression model. Based on a panel data set of 137 economies during 1990-2014, the analysis identifies a threshold effect of income growth on energy intensity change: although energy intensity is negatively correlated with income growth throughout the entire sample and study period, the declining rate significantly slows by more than 30 percent after the level of per capita income reaches USD 5,000. Based on index decomposition, the analysis also finds that although structural change is important for intensity levels in all countries, the efficiency effect is more important in higher-income countries. The results suggest that when countries move beyond lower-middle-income levels, energy efficiency policies become far more critical for sustaining the rate of improvement in energy efficiency
