Changes of Carbon Emission Intensity from Industrial Energy Use in China

摘要

Decomposition analysis has been popular in the study on influencing factors of CO2 emissions. This paper analyzes the change of CO2 emission intensity in China over the period 1980-2007 based on a complete decomposition approach-the logarithmic mean divisia index (LMDI) method, and examines the factors driving the changes of CO2 emissions intensity. The research shows that energy intensity is the main influence factor for CO2 emission intensity decrease in China over the entire period, China has achieved a considerable decrease in CO2 emission intensity mainly due to the improved of energy intensity. In addition, the change of energy structure exhibits positive effect to CO2 emission intensity increase. According to research, the author suggests CO2 emission intensity reduction strategies should aim at accelerate technological innovation and industrial structural adjustments; diversify energy supply with preference on renewable energy and perfect environment protection management system.
