China is the most important steel producer in the world,and its steel industry is one of the most carbon-intensive industries in China.Consequently,research on carbon emissions from the steel industry is crucial for China to achieve carbon neutrality and meet its sustain-able global development goals.We constructed a carbon dioxide(CO2)emission model for China's iron and steel industry from a life cycle perspective,conducted an empirical analysis based on data from 2019,and calculated the CO2 emissions of the industry throughout its life cycle.Key emission reduction factors were identified using sensitivity analysis.The results demonstrated that the CO2 emission intensity of the steel industry was 2.33 ton CO2/ton,and the production and manufacturing stages were the main sources of CO2 emissions,ac-counting for 89.84％of the total steel life-cycle emissions.Notably,fossil fuel combustion had the highest sensitivity to steel CO2 emissions,with a sensitivity coefficient of 0.68,re-ducing the amount of fossil fuel combustion by 20％and carbon emissions by 13.60％.The sensitivities of power structure optimization and scrap consumption were similar,while that of the transportation structure adjustment was the lowest,with a sensitivity coeffi-cient of less than 0.1.Given the current strategic goals of peak carbon and carbon neutrality,it is in the best interest of the Chinese government to actively promote energy-saving and low-carbon technologies,increase the ratio of scrap steel to steelmaking,and build a new power system.
