EU digital battery passport mandate next year raises worries for small suppliers in South Korea

South Korea\'s battery supply chain is facing a test as the European Union\'s digital battery passport mandate approaches next year. Major cell makers have set up response systems, but many small materials suppliers lack IT systems and specialist staff to measure carbon emissions. Carbon data for the passport requires lifecycle assessment information from multiple tiers of suppliers. Industry groups say small and mid-sized firms lack expertise, budget and manpower, widening gaps with large companies.
