Values shown are estimates for planning. The binding carbon footprint declaration must follow the Commission Delegated Regulation methodology and be verified by a notified body. Use this tool to structure the data, then commission a verified LCA.

About the Battery Carbon Footprint

Carbon footprint is mandatory in the battery passport, expressed as kg CO2e/kWh. Structures lifecycle stages, computes per-kWh value and performance class, formats per EU methodology.

How to use

Enter lifecycle emissions, get declaration with performance class.
