广东省电力生产活动碳排放特征研究

Analysis of the CO2 Emissions by Electricity Production Activities in Guangdong

摘要:

通过收集整理广东电力生产分品种燃料消费量和排放因子，计算得到2005-2016年全省电力CO2排放量，探析电力生产CO2排放特征，结合Tapio脱钩理论量化其与电力消费、经济发展及火力发电量的同期变化情况，并分析单位发电碳排放量与单位用电产出经济效益的变化情况。结果显示，2005-2016年间，广东省电力生产活动CO2排放量与火力发电量变化趋势基本一致，呈先波动上升，后缓慢下降态势；煤炭消耗仍是电力生产GHG排放的主要来源。因此，全省应从机组改造、优化能源结构和落后产能淘汰等环节入手控制电力生产CO2排放。

Abstract:

The energy consumption and emission factor of different types from relevant material was employed to estimate CO2 emissions from electricity generation in Guangdong province, analyze the activities of CO2 emissions by electricity generation, the change of CO2 emissions and electricity consumption, economic development, thermal power generation of the same period were quantified by Tapio decoupling theory, then analyze the change of carbon emission per unit of electricity generation and economic benefits per unit of electricity consumption. The results shows that the trend of CO2 emissions from electricity generation was increased firstly after declining, the variance of trend is essentially same with thermal power generation from 2005 to 2016 in Guangdong province. Coal consumption continue to be the leading source of CO2 emissions from electricity generation Therefore, it should control CO2 emission from electricity generation in the fields of unit transformation, optimization of energy structure and elimination of backward production capacity.
