Characteristics of Carbon Dioxide Emission in Chinese Power Industry and its Dynamic Development

采用CO2排放数学模型计算2000—2009年中国电力工业CO2的排放量,分析CO2排放量及排放强度的动态变化特点。结果表明,十年间中国电力工业CO2排放总量逐年增长,人均CO2排放量由2000年的231 kg增加到2009年的509 kg,平均增长14.01%。单位产品CO2排放强度由0.263 kg/(kW·h)下降到0.228 kg/(kW·h),平均下降1.56%。每万元GDP CO2排放量由295 kg下降到200 kg,平均下降3.54%。电力工业十年间实施节能降耗、资源循环利用、提高经济效益等措施,对于减少CO2排放具有明显效果。

The mathematical model is used to calculate carbon dioxide emission in Chinese power industry during 2000-- 2009 and analyze the dynamic change of emissions of C02 and emission intensity. The results indicate that the total emissions of CO2 increase year by year in china and carbon dioxide emissions per capita increases from 231 kg in 2000 to 509 kg in 2009,increasing 14.01% in average.Carbon dioxide emissions intensity per unit of output decreases from 0.263 kg/（kW. h） to 0.228 kg/（kW h）,decreasing 1.56% in average. Carbon dioxide emissions per million dollars GDP decreases from 295 kg to 200 kg, decreasing 3.54%. The result shows that the use of some measures can obviously decrease the emissions of carbon dioxide, such as energy saving and consumption reduction, resource recycling and increase of economic benefits.
