Decoupling Transport CO2 from GDP

Abstract

The sectors that contribute the most to the growth of greenhouse gas emissions are energy supply, transport and industry. Transportation accounted for 26% of global CO2 emissions in 2007. Transport and the economy have been connected with one another for many decades. The growth of CO2 emissions from transport has followed the growth of the gross domestic product, especially in Europe, Africa and South and Central America. Decoupling the link between economic growth and environmental harm is a major societal challenge. The goal of this study is to broaden the scope of decoupling research within the transport sector to a global level and test the significance of the decoupling framework entitled Decoupling Diamond. A total of 137 countries and 4 groups of countries are included in the study.
