摘　　要：钢铁工业是资源和能源密集型工业,需要消耗大量的化石能源,导致温室气体大量排放。根据京津冀地区钢铁行业的发展现状,对温室气体核查方法进行了研究,对京津冀地区的一家重点钢铁生产企业进行了能耗调研,识别了该企业CO2的排放源,利用开发的方法学进行了量化计算。核查可知,该企业2018年炼焦、烧结、炼铁、炼钢和钢材深加工环节CO2的排放量分别为-6.40×10^4t、7.574×10^5t、1.596 3×10^6t、-2.655×10^5t、8.475×10^5t,其工业生产过程排放量为5.970×10^5t,固碳产品隐含的排放量为1.773×10^5t。活动水平数据的不确定性为±3.54%,属于高精度等级。研究可以帮助钢铁生产企业核查其各个环节的温室气体排放量,挖掘减排潜力,促进钢铁行业低碳转型。The iron and steel industry is a resource and energy intensive industry,which needs to consume a lot of fossil energy,resulting in a large number of greenhouse gas emissions.According to the development status of iron and steel industry in Beijing-Tianjin-Hebei Region,this paper studied the greenhouse gas verification method,investigated the energy consumption of a key iron and steel production enterprise in Beijing-Tianjin-Hebei Region,identified the CO2 emission source of the enterprise,and made quantitative calculation by using the development methodology.It can be seen from the verification that in 2018,the CO2 emissions of coking,sintering,iron making,steel making and steel deep processing links of the enterprise were-6.40×10^4 t,7.574×10^5 t,1.596 3×10^6 t,-2.655×10^5 t and 8.475×10^5 t respectively,and the emissions of its industrial production process were5.970×10^5 t,and the implicit emissions of carbon fixation products were 1.773×10^5 t.The uncertainty of activity level data is ±3.54%,which belongs to high precision level.This study can help iron and steel enterprises to check their greenhouse gas emissions in all aspects,tap the emission reduction potential,and promote the low-carbon transformation of the iron and steel industry.
