Regional variation of energy-related industrial CO2 emissions mitigation in China

This paper analyzes the reasons for regional variations in industrial CO₂ emissions mitigation. First, regional industrial CO₂ emissions during the “11th Five-Year Plan” period are calculated based on the presented method. Then a two-level perfect decomposition method, LMDI, is used to find the nature of the factors that influence the changes in energy-related industrial CO₂ emissions in nine economic regions in China. The changes of industrial CO₂ emissions are decomposed into energy emission factor effect, energy structure effect, energy intensity effect, industrial structure effect and economic output effect. As the results suggest, rapid growth of industry is the most important factor responsible for the increase in CO₂ emissions. The adjustment of both industrial structure and energy structure contributes to the increase of CO₂ emissions slightly. Energy consumption per unit GDP is the most important measure of CO₂ emissions and the energy emission factor by itself also makes a weeny contribution to CO₂ reduction as a result of electricity generation efficiency enhancement.
