Amid the accelerating electrification of the global automotive industry, power batteries, as the core components of new energy vehicles (NEVs), have become a strategic focal point in the global competition to achieve green and low-carbon automotive development. Currently, China leads the world in power battery technology, industrial scale, and supporting ecosystem. This paper investigates the carbon footprint accounting methods for power batteries, comprehensively studies the current development status and challenges of China's power battery carbon footprint, and deeply analyzes the experiences and insights gained from the EU's carbon footprint management. It is proposed to accelerate the improvement of the top-level design for carbon footprint management, establish a comprehensive carbon footprint accounting framework, facilitate international mutual recognition of accounting systems, explore the market-oriented operation of power battery carbon footprints, and promote mutual recognition of international standards and regulations.
