Abstract: Based on a set of World Input-Output Tables (WIOT) in1995 and 2008, this paper empirically measures carbon emission embodied in per unit of value added of exports for the main developed and developing countries. By using structural decomposition technique, this paper also explores the underlying reasons behind both changes over time and the difference over space for the countries. It is found that developing countries experienced faster decrease in carbon embodied in per unit value added of exports than developed countries during 1995-2008. However, until 2008, the developing countries are still responsible for much higher carbon emission than developed countries when they receive as same as value added from exports. The structural decomposition shows that the differences in carbon reduction technique (indicated as contribution of carbon intensity) are one of the most important reasons. From the aspect of global carbon reduction, it seems very important to encourage the technique transfer from developed countries to developing countries.
