Abstract：In 2020,China announced that it will increase its nationally determined contributions and strive to reach the peak of CO2 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.
