1、 燃煤发电行业碳足迹评估 摘要 随着气候变化越来越成为国际国内各界关注的焦点，一个新的概念 “碳足迹”应运而生。碳足迹是从消费端出发的 CO2排放量，用来衡量人类生产生活中的能源活动排碳对气候变化的影响，比传统意义上的碳排量更加形象而科学。在我国，电力行业作为 CO2减排的主力军，减排任务十分艰巨。因此，了解 燃煤发电行业 的碳足迹情况对于 燃煤发电行业 的节能减排有着指导性的意义 .本课题主要运用碳排放生命周期分析法分析研究 ，对我国燃煤发电行业整体进行碳足迹评估 。这种分析方法以过 程分析为基本出发点，通过研究对象的生命周期输入和输出数据清单，计算研究对象的全生命周期的碳排放 ， 最终 得
2、到企业全生命周期中的碳足迹分布，发现 燃煤发电行业 的碳减排潜力主要在于锅炉燃煤和煤炭开采，但在运输、尾气脱硫等部分的碳排放绝对量也是不可忽视的， 因此，燃煤发电行业 在节能减排时应全面统筹，有的放矢。 关键字 ：碳足迹、燃煤发电行业、生命周期、碳排放 Carbon footprint assessment of coal-fired power industry ABSTRACT As climate change is becoming the focus of international concern, a new concept - carbon footprint emerge a

A carbon footprint is based on CO2 emissions from the consumption end, used to measure energy in human production and life activities of carbon on the impact of climate change on carbon emissions, than the traditional sense of the image and science. In our country, the electric
4、power industry as the main force of CO2 emission reduction, emission reduction task is very arduous. Therefore, understanding has a guiding significance to energy saving and emission reduction of carbon footprint of coal-fired power industry for coal-fired power industry. The main topic of the use o
