Abstract: As an effective tool for analyzing the environmental impact of the product system, the product life cycle assessment method is of accurate guiding value for Chinese industrial production chain. The development process of life cycle assessment (LCA) and the latest research on the application of LCA theory were analyzed, and the weakness of environmental impact assessment of industrial products in China was investigated. In view of the current problems in LCA in China, it is proposed that the development of life cycle software be strengthened, the research on product environmental impact assessment models be strengthened, and the authenticity and sensitivity of product data be guaranteed to further standardize the green transformation of enterprises and make sure that the industrial products can better serve the society and provide strong support for the sustainable development of China's industry.
