天然气有效利用对减少城市温室气体排放的分析

摘要

本文采用生命周期的方法,从温室气体排放和综合成本的角度,对北京地区用于发电、供热、交通、公服、居民炊事的主要能源进行了对比研究.结果表明,在主要能源应用领域,在整个燃料链生命周期内,天然气与其他能源相比,在排放和成本方面具有一定优势.%From the perspective of greenhouse gas emissions and integrated costs,the life cycle methodology is adopted to compare the main energy sources in Beijing including power generation, heating, transportation, public service, residents cooking. The results show that throughout the fuel chain life cycle, natural gas has certain advantages in terms of cost and emissions than other energy sources in the main application areas of energy.
