Abstract: Based on the analysis of carbon emission in China's steel industry, some corresponding solutions are put forward in this paper. Individual enterprises should realiza energy conservation and emission reduction as far as possible and at the same time improve the level of production process. We should actively promote the development of steel supply chain, promote the cooperation among enterprises in the chain, reduce carbon emissions, and realize the green development of the supply chain. Enterprises can implement low-carbon emission independently through the use of carbon tax and other incentives and supervision means by related functional departments.
