Abstract：In the current context of "carbon peak" and "carbon neutrality", many steel companies are formulating low-carbon plans. However, they have no digital concept on the potential of carbon reduction measures, and lack of quantitative evaluation methods and scientific data support. A method for applying life cycle assessment (LCA) to low-carbon planning for steel enterprises was proposed, and the relationship between product carbon footprint and organization-level carbon accounting was established. On this basis, through the company-wide product life cycle assessment model, it was possible to quantitatively evaluate the carbon emission reduction performance of the strategies such as the application of new technologies and new processes, product structure changes, energy structure changes, increased utilization of scrap steel, energy conservation and emission reduction, and supply chain optimization at the company organization level. In this way, the digital carbon emission reduction roadmap could be described. Examples of assessing the carbon emission reduction potential of various measures by LCA were listed, which provide reference for the low-carbon planning of steel companies.
