摘要中国政府高度重视气候变化问题,积极主动地做出了减排承诺。钢铁行业作为工业的重要领域,是能源消费大户,同时也是CO₂排放大户。对中国钢铁工业CO₂排放现状分析表明,中国钢铁工业吨钢CO₂排放量下降明显,CO₂排放总量在2014年已经达到峰值,随后呈下降趋势,但由于粗钢产量巨大,钢铁工业的CO₂排放量占全国CO₂排放总量仍然较高,必须走脱碳化发展的道路。通过对钢铁工业脱碳化发展策略和技术的分析,表明有策略地推进并提高全废钢电炉流程的比例是当前最为实际的钢铁工业脱碳化发展途径。

Abstract：The Chinese government has paid great attention to the issue of climate change,and has actively made emission reduction commitments. As an important field of industry,the steel industry is not only a big energy consumer but also a major CO₂ emission source. The current situation of CO₂ emission from the Chinese steel industry was analyzed,and it is shown that the specific CO₂ emission per ton steel has decreased significantly. And the total amount of CO₂ emission has reached a peak in 2014,and then has shown a downward trend. However,due to the huge output of crude steel,the CO₂ emission of the steel industry still accounts for a high proportion of the total CO₂ emission in China. Therefore,it is necessary to take the road of decarbonization for the steel industry. Through the analysis of the development strategies and technologies of decarbonization in the steel industry,it is shown that the most practical pathway for decarbonization development of the steel industry is to promote and increase the ratio of EAF process with 100% scrap strategically.

Key words： decarbonization steel industry climate change CO₂ emission EAF process
