With the improvement of people’s living standards, the use of electronic and electrical products is also increasing. It is followed by more and more serious environmental pollution problems. In the life cycle process of electronic and electrical products, the use of raw materials, production and processing, transportation and storage, sales and use will produce different degrees of greenhouse gas emissions. Therefore, it is very necessary and urgent to calculate the carbon footprint of electronic and electrical products. Therefore, this paper takes electronic and electrical products as the research object. Based on the life cycle theory, the greenhouse gas emission calculation is carried out in each stage of the production process, and the greenhouse gas generated in different stages is calculated in detail. Through calculation and analysis, the greenhouse gas emission and main influencing factors generated in different stages are obtained. It is hoped to provide theoretical reference for carbon footprint accounting of electronic and electrical products in China in the future.
