The Corporate Sustainability Reporting Directive (CSRD) requires large companies to report on sustainability matters in a standardised way. It is a reporting obligation at company level, distinct from the product-level battery passport.
They overlap in the data they rely on: carbon-footprint figures and supply-chain due-diligence information feed both your CSRD disclosures and your battery passports. Collecting that data once, in a structured form, serves both obligations.
