Decomposition of Energy and CO2 Emission of China between 1980 and 2005

In 2005, Chinapsilas energy consumption amounted to 2233 million tons coal equivalent (MtCE), and the CO₂ emission was 5322.69 million tons, making China the worldpsilas second largest consumer of energy products and source of CO₂ emissions behind only the United States. This paper analyses the change of energy consumption and aggregated CO₂ emission in China from 1980 to 2005 based on a complete decomposition method. During this period, the energy saving rate was 33.35%, and the decarbonization rate for the period was 16.06%. The study indicates that China has achieved a considerable decrease in its energy consumption and CO₂ emissions mainly due to the improvement of energy efficiency.
