Abstract：Product carbon footprint (PCF) is an effective method to quantitatively determine or calculate the greenhouse gas emissions during a product life cycle. Through product carbon footprint assessment, it can effectively guide and help enterprises to understand the impact of production and living on climate change, take feasible measures to reduce carbon emissions in the supply chain, and even affect consumer behavior and enterprise production decisions.The results of PCF are becoming the pivotal parameters for traceability information management in the international trade supply chain with the increasing emphasis of legislative issues on global climate change. As the largest producer and consumer of steel products all over the word, China also exported a large volume of indirect steel products such as mechanical and electrical products. It is necessary to put more focus on studying PCF of steel products in China and the iron and steel industry should be ready for international integration in order to deal with the international trade carbon tariffs (CT), carbon labelling(CL) and other related legislative requirements. The legislation requirements on "carbon peaking" and "carbon neutralization" in China as well as the necessary of low-carbon emissions in China's steel industry have been introduced briefly. Meanwhile, the significances for carrying out PCF evaluation of metallurgical products in China's steel industry have been also analyzed. The suggestions on how to accelerate the drafting PCF standards of metallurgical products for China's steel industry have been put forwards based on domestic and foreign evaluation standards on PCF and CL.
