The Digital Product Passport (DPP), central to the 2024 Ecodesign Regulation, enhances transparency and sustainability in product value chains. As part of the upcoming European battery regulation, digital battery passports (DBPs) will be mandatory for industrial and electric vehicle batteries (EVBs) from 2026. While DBPs include environmental data, social aspects remain underexplored. This study uses a mixed-methods approach, combining literature reviews and workshops, to identify key social issues in the EVB value chain, such as worker health, fair wages, child labour, and education. Integrating social factors into DBPs is essential for holistic sustainability and ethical industry practices.
