The study of carbon emissions embodied in exports of China

An input-output model was established to calculate embodied-carbon in China's exports in 2002 and 2007. By using logarithmic mean Divisia index (LMDI) method, the factors was analyzed which influenced the embodied carbon emission in total and sectoral level separately. The results show that compared with 2002, total embodied emissions in China increase significantly in 2007. There is obvious differences among sectors. In total amount, effects of scale catalyze the emission significantly, while impacts of structure effects are less significant; technology effects results in the decline of carbon embodied in exports. On sector level, effect of scale is the most important factor which increases the carbon emission embodied in exports. Effect of openness changes with embodied carbon emission at the same direction. Technology effects decrease the carbon emission embodied in exports of each sector.
