[Supply Chain] BMW and CATL Sign MoU on Battery Passport and Decarbonisation — Piloting Cross-Border Data Exchange via Catena-X

Source:CATL / BMW Group
On 25 February 2026, CATL and BMW signed an MoU on pilot projects covering cross-border data transfer in battery passport scenarios and the calculation of battery carbon footprints. Using Catena-X, the two companies will explore data exchange and the alignment of technical standards. This can be seen as one example of corporate testing and preparation ahead of the EU battery passport requirement that applies from February 2027.
Editor's View

In battery regulation, what matters is not only the product itself but also the ability to digitally connect data on raw materials, manufacturing processes and carbon emissions. Not only automakers and battery makers but also component and raw material suppliers are expected to collect, prepare and share data usable in battery passports. By looking not only at when regulations take effect but also at what data infrastructure companies are building beforehand, it is possible to grasp the changes under way at the implementation stage.

EU Battery Regulation

The EU Battery Regulation (Regulation (EU) 2023/1542) comprehensively overhauls the former Battery Directive (2006/66/EC) and is a directly applicable regulation governing the entire lifecycle — from raw material sourcing through design, production, reuse, and recycling — of all batteries placed on the EU market, including electric vehicle, industrial, light means of transport (LMT), portable, and starting-lighting-ignition (SLI) batteries. It imposes some of the world's most stringent environmental and traceability requirements, including disclosure and caps on carbon footprint, the introduction of the Digital Battery Passport, mandatory supply chain due diligence, minimum recycled-content requirements for raw materials (cobalt, lithium, nickel, and lead), and raised targets for waste-battery recycling efficiency and material recovery.
