Abstract:This paper presents a decomposition analysis of energy-related CO(2) emission in China for the period 19912006 divided into three equal time intervals. The complete decomposition method developed by Sun is used to analyze the nature of the four factors: CO(2) intensity, energy intensity, structural changes and economic activity. The results show that economic activity has the largest positive effect in CO(2) emission changes in all the major economic sectors and China has achieved a considerable decrease in CO(2) emission mainly due to the improved energy intensity. However. the impact of CO(2) intensity and structural changes is relatively small. Structural changes only exhibit positive effect to the CO(2) mitigation in agricultural sector, and CO(2) intensity also contributes to the decrease of CO(2) emission in transportation sector. Moreover, a formula about CO(2) mitigation is presented in this paper, which shows that China has made a significant contribution to reducing global CO(2) emission. (C) 2009 Elsevier B.V.
