摘　　要：我国钢铁产量连续11a位居世界第一,同时也消耗了大量的化石燃料,排放出大量的温室气体.根据联合国政府间气候变化专门委员会(IPCC)的通用方法计算我国钢铁工业的碳排放情况并进行研究分析.结果显示:1994—2006年内钢铁工业碳排放量平均占碳总排放的14%,煤炭类能源产生的CO2平均占钢铁工业碳排放量的97%,钢铁年产量的增长伴随着CO2排放量的增加且两者的相互依赖性有加强的趋势,但1994—2006年内吨钢CO2排放量呈降低的趋势.因此,钢铁工业是我国碳减排的重点行业,其碳减排工作应该尽快展开,而优化能源消费结构是最有效的减排路径,此外也要加强技术创新或是引进国外先进技术以提高能源利用效率.The yield of chinese iron and steel industry has been ranked NO.1 in the world for 11 years running,while at the same time,Chinese iron and steel industry has consumed a great deal of fossil fuel and discharged large amounts of greenhouse gas.The calculation and relevant analysis of the carbon emission by Chinese iron and steel industry have been done based on a common method of IPCC.The results indicate that the CO2 emission generated by China iron and steel industry is enormous.It accounted for 14% of the total CO2 emissions in this country on average from 1994 to 2006,with an enormous proportion of 97% CO2yielded by coal-type energy.The output of Chinese iron and steel industry increased with the growth of CO2 emission,and there was a growing trend toward reinforced interdependence between the two factors.But during the years 1994—2006,CO2 emissions per ton showed a declining trend.Therefore,the iron and steel industry is one of the key C Mitigation industries in China,and C Mitigation should be started as soon as possible.Optimizing energy consumption structure is the most effective approach to mitigation.In addition,the technological innovation or introduction should be enforced to improve energy efficiency.
