    In spite of the extensive literature on greenhouse gas emission inequalities at the world-wide level, most of the evidence so far has been based on country-level data. However, the within-country dimension matters for both the implementation and the policy formation of climate policies. As a preliminary step towards a better understanding of within-country inequalities, this paper measures their extent for the two major greenhouse gases, CO2 and CH4, over the 1970–2008 period. Using Theil-index decompositions, we show that within-country inequalities account for the bulk of global inequality, and tend to increase over the sample period, in contrast with diminishing between-country inequalities. Including differences across sectors reveals that between-sector inequalities matter more than between-country inequalities, and between-sector inequalities become the dominant source of global inequality at the end of the sample period in the CO2 case. Finally, estimated social tensions arising from the disconnection between emissions and future damages turn out to be increasing as soon as within-country disparities are taken into account. These orders of magnitude should be kept in mind while discussing the efficiency and fairness of alternative paths in combating global warming.

    Climate change: responsibilities and policy : four essays in environmental economics
    (2015)

    This thesis investigates empirically three important aspects in the context of climate change: regulatory responsibility, the measurement of observed environmental policy stringency as well as the impact of the latter on anthropogenic CO2 emissions. Although distinct, all three aspects are inherently interrelated, and a proper understanding is crucial in order to effectively combat climate change. Part 1 contains two introductory descriptive analyses on the distribution of greenhouse gas emissions on the world surface. This provides a detailed quantitative basis, allowing to shed light on the responsibility debate in the context of human induced climate change. The results clearly indicate the historical responsibility of the West, but suggest that the responsibility of countries in terms of applied regulations is converging, while the one of specific sectors and zones is rapidly diverging. Part 2 outlines a coherent methodological framework allowing to measure environmental policy stringency and implements the latter for several pollutant specific policies. Part 3 investigates empirically the relationship between greenhouse gas policy stringency and anthropogenic CO2 emissions. Results indicate that increased greenhouse gas policy stringency lowers national CO2 emissions, although by a rather small extent. Moreover, results show that increased policy stringency improves CO2 efficiency of sectors and alters the sectoral composition of economies by increasing the share of relatively clean sectors.
