    A Global Compass for the Great Divergence: Emissions vs. Production Centers of Gravity 1820‐2008

    We construct the world's centers of gravity for human population, GDP and CO2 emissions by taking the best out of five recognized data sources covering the last two centuries. On the basis of a novel distorsion‐free representation of these centers of gravity, we find a radical Western shift of GDP and CO2 emissions centers in the 19th century, in sharp contrast with the stability of the demographic center of gravity. Both GDP and emissions trends are reversed in the first half of the 20th century, after World War I for CO2 emissions, after World War II for GDP. Since then, both centers are moving eastward at an accelerating speed. These patterns are perfectly consistent with the lead of Western countries starting the industrial revolution, the gradual replacement of coal by oil and gas as alternative sources of energy, and the progressive catch up of Asian countries in the recent past.

    Climate change: responsibilities and policy : four essays in environmental economics

    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.
