Decomposition of Energy-Related CO2 Emission over 2001 and 2011 in Manufacturing Industry of China

Manufacturing industry is developing fast in China, leading to a large amount of energy consumption and CO₂ emission. This paper presents a decomposition analysis of energy-related CO₂ emission in manufacturing industry in China for the period of 2001-2011. The complete decomposition method developed by Sun is used to analyze the effect of four factors: CO₂ intensity, energy intensity, structure change and economy development. The results show that economy development has the largest positive effect and energy intensity has the most negative impact on CO₂ emission of Chinas manufacture industry. While the structure change of manufacturing industrial decreases its CO₂ emission to a certain extent and the CO₂ intensity increases its CO₂ emission slightly, but both of them have large potentials in CO₂ reduction.
