Abstract:

On the basis of systematically analyzing the consumption structure, growth rate and consumption elasticity of western China, the paper uses the classic emission factor method to calculate the carbon emission volume and intensity from energy consumption in western Chinas 12 provinces from 1990-2010, and uses the factor decomposition method to analyze their drives. The results show an annual growth rate of 8〖KG-*3〗3% in energy consumption, of which coal contributes more than 70%, and a decrease of 61% in carbon emission intensity, of which 18% is from the period of “the 11th fiveyearplan”. GDP growth and technological progress are the two major factors to reduce the amount and intensity of carbon emissions.

摘要：

在系统分析中国西部地区能源消费结构、增长速度、消费弹性系数的基础上，利用经典的排放系数法分别计算了西部12省市自治区1990—2010年能源消费碳排放量和能源消费碳排放强度，同时，应用分解方法对能源消费碳排放量和碳排放强度及其变化的驱动因素进行分析。结果表明，20年间西部地区能源消费年均增长83%，其中煤炭消费占西部地区能源消费量的70%以上，能源消费碳排放强度总体下降了61%，其中“十一五”期间下降了18%。GDP增长和技术进步分别是促使能源消费碳排放量和碳排放强度变化的最主要因素。
