With the deepening of the global response to climate change, the carbon footprint of products has become an important competitiveness indicator of the global trade supply chain, and the high carbon footprint of steel per unit product is an important challenge for the sustainable development of the steel industry. Research on the carbon footprint of steel products has important value for China to achievethe “dual carbon” goal and the response to international green trade barriers. After the analysis of the concept of product carbon footprint, this paper uses practice data to analyze the main factors affecting the carbon footprint of steel products, including product type, energy structure, technological process and the use of carbon reduction technology, countermeasures and suggestions for reducing carbon footprint of steel products are proposed based on the above influencing factors: strengthen the deep integration of the upstream and downstream industrial chains of steel enterprises, promote the iterative upgrading of products in the upstream industry according to the requirements of the downstream industry to reduce carbon emissions throughout the product life cycle; optimize the composition of incoming raw materials and energy for steel smelting, increase the proportion of new and renewable energy used; According to the domestic scrap resources, there are plans to carry out the promotion of short process steelmaking to maximize the carbon reduction advantages of short process steelmaking; Accelerate the promotion of green and low-carbon technologies such as high-temperature and high-pressure dry quenching technology, waste heat recovery and efficient power generation technology from sintering flue gas, and high efficiency power generation technology from blast furnace TRT, explore the application of carbon capture and utilization technology in the steel industry.
