摘要：本文提出了针对钢铁生产的碳排放和碳足迹计算方法，并通过计算模型计算了两个典型钢铁企业的碳排放和碳足迹，进而研究了整个钢铁行业的碳排放和碳足迹情况。通过对企业所在地和全国整体植被调查，由于绿色植被面积与碳足迹存在差距，导致碳赤字。考虑到绿色植被增速缓慢，碳赤字逐年增加，因此企业内部的能源结构优化和节能技术等碳减排策略，对于钢铁工业的可持续发展具有非常重要的意义。
The analysis of the carbonfootprint and the carbon deficit in china’s steel industry
Key words：Carbon emissions；Carbon footprint ；Carbon deficit；Emission reduction strategy
Abstract：The emission of CO2 and carbon footprint of two typical steel works with integrated process and iron and steelindustry in China werecalculated and analyzed by a carbon footprint method based on a CO2 emission model in iron andsteel making. The carbon footprint of iron and steel industry in China showed a tendency of rapid increase from 1991 to 2010. Through theinvestigation of local and national vegetation survey, it is found that there exists the carbon deficit of iron and steel industry. Considering the slowgrowth of green vegetation, carbon deficit of iron and steel industry has been increasinggradually. Thus, the internal carbon reduction strategy,such as energy structure optimization and energy saving technology, was mainlyencouraged for the sustainable development of iron and steel industry in China.
