中国钢铁工业碳达峰及低碳转型路径

Carbon peak and low-carbon transition path of China’s iron and steel industry

2020年中国宣布将提高国家自主贡献力度,二氧化碳排放力争在2030年前达峰。钢铁工业作为典型的资源、能源密集型行业,是率先落实碳达峰的重要行业。分析了钢产量、生产结构、节能减排技术和碳税等因素对中国钢铁工业碳排放的影响程度。研究表明,不同的钢产量达峰时间将对钢铁工业的碳达峰产生不同影响,技术和生产结构因素也将对中国钢铁工业产生重要影响。地方区域是落实国家碳达峰任务的责任主体,对京津冀及周边地区、长三角地区、汾渭平原和两广地区4个具有不同钢铁生产特点的重点区域碳排放进行研究,并分析了区域达峰方案。加快调整产业结构、推广低碳技术、改变能源结构、推进产业间耦合和加强碳资产管理等方面制定钢铁工业低碳转型路径,对实现中国钢铁工业碳排放早日达峰和碳中和有重要意义。

In 2020,China announced that it will increase its nationally determined contributions and strive to reach the peak of CO_(2) emissions by 2030.As a typical resource-and energy-intensive industry,the iron and steel industry is an important industry that takes the lead in achieving carbon peaks.Here,the influences of steel production,production structure,energy conservation and emission reduction technologies,and carbon tax on the carbon emissions of China′s iron and steel industry were analyzed.That different steel production peak times will have different effects on the iron and steel industry′s carbon peak,and technologies and production structure factors will have an important impact on China′s iron and steel industry.The region is the main body responsible for implementing the national carbon peak task.The carbon emissions of four key areas(Beijing-Tianjin-Hebei and surrounding areas,the Yangtze River Delta region,the Fenwei Plain and the Guangdong and Guangxi regions)with different steel production characteristics were analyzed,which is necessary to speed up the formulation of the regional peaking plan.To formulate a low-carbon transformation path for the iron and steel industry(in terms of adjusting the industrial structure,promoting low-carbon technologies,changing the energy structure,promoting inter-industry coupling,and strengthening carbon asset management)is of great significance to achieving the early peak of carbon emissions and carbon neutrality in China′s iron and steel industry.
