Battery Industry Carbon Footprint: Global Policy Comparison

This document provides a comparative analysis of international policies and regulations on carbon footprint in the battery industry. It covers the EU battery regulation (2023/1542) which mandates carbon footprint declarations, classifications, and limits for EV, industrial, and LMT batteries, using the Product Environmental Footprint (PEF) method. The EU Carbon Border Adjustment Mechanism (CBAM) is also discussed. Japan's Ministry of Economy, Trade and Industry (METI) has issued power battery carbon footprint disclosure requirements, initially linking them to subsidy eligibility, with plans for future emission caps. The US Clean Competition Act proposes fees on high-carbon products, including batteries, to incentivize cleaner production. The document highlights the significance of carbon footprint as a policy control indicator, noting that battery production accounts for a major share of vehicle emissions. It compares similarities and differences among these policies, emphasizing the need for manufacturers to comply with multiple standards and the potential for future cooperation on unified accounting standards.
