摘要
纯电动轿车燃料周期的温室气体排放是否低于汽油轿车的排放仍然存在争议.为评价纯电动轿车的温室气体减排效率,此研究利用中国2007温室气体排放EIO-LCA模型分别核算了普通级纯电动轿车和汽油轿车燃料周期的温室气体排放量.结果表明纯电动轿车燃料周期的温室气体排放总量为124gCO2,e/km,汽油轿车相应的排放总量为265gCO2,e/km,纯电动轿车与汽油轿车相比,减排温室气体53%.模型计算结果还表明影响纯电动轿车温室气体排放的主要行业包括电力、热力的生产和供应业与煤炭开采和洗选业等.因此,纯电动轿车温室气体减排应通过优化一次能源结构、提高电网综合效率等方法实现.
It was still controversial that whether fuel-cycle greenhouse gas（GHG） emissions from battery electric automobile（BEA） are lower than that from gasoline automobile（GA）.For analyzing the fuel-cycle GHG emissions reduction from BEA in China,this article accounted fuel-cycle GHG emissions of general BEA and GA based on ＂China 2007 GHG Emissions EIO-LCA＂ model.The results showed that the fuel-cycle GHG emissions were 124 gCO2,e/km for BEA and 265 gCO2,e/km for GA.Therefore,compared to GA,BEA could reduce GHG emissions by 53%.Furthermore,the results showed that the main sectors that affect the GHG emissions of BEA included ＂Production and Supply of Electric Power and Heat Power＂ and ＂Mining and Washing of Coal＂,etc.The GHG emissions of BEA could be reduced by primary energy structural optimization and efficiency improvement of electric networks,etc.
