EU Batteries Regulation 2023: What the Carbon Footprint and Due Diligence Rules Mean for Your Supply Chain

What the EU Batteries Regulation Actually Requires#

The EU Batteries Regulation (EU) 2023/1542 entered into force in August 2023, replacing the 2006 Batteries Directive. It applies to all battery categories: portable, light means of transport (e-bikes, e-scooters), industrial, and electric vehicle. The regulation is directly applicable across all EU member states, meaning there is no transposition into national law — the same rules apply in Germany, France, and every other member state simultaneously. The headline obligations cover four areas: carbon footprint declarations, recycled content minimums, supply chain due diligence, and the battery passport. Each area has its own implementation timeline, with the most demanding requirements applying from 2026 onwards for EV and industrial batteries.

Carbon Footprint Declarations: Timelines and Scope#

From February 2025, EV batteries and rechargeable industrial batteries above 2kWh must carry a carbon footprint declaration covering the full lifecycle — extraction, processing, manufacturing, and end of life. Portable battery declarations follow from August 2025. The declaration must reference a carbon footprint performance class (A through E, with A being best), calculated using EU methodology. Batteries in the worst-performing classes will eventually be barred from the EU market, though the threshold dates have not yet been set. For UK manufacturers or exporters supplying EU customers, this means commissioning lifecycle assessments and integrating carbon data into your product documentation well before the declaration date. AskBiz tracks regulatory deadline calendars so your team is alerted when key compliance dates approach.

Recycled Content Requirements: The Numbers#

From 2031, EV batteries must contain minimum recycled content of 16% cobalt, 85% lead, 6% lithium, and 6% nickel by weight. By 2036, the cobalt target rises to 26% and lithium to 12%. Industrial batteries face equivalent requirements. These targets represent a significant engineering and procurement challenge: battery cells will need to be sourced from manufacturers who can demonstrate certified recycled content. For businesses in the battery supply chain today — cathode material suppliers, cell manufacturers, pack assemblers — this requires working backwards from 2031 to identify which upstream suppliers can meet future content standards. Procurement decisions made now will determine whether your supply chain is compliant in seven years.

Due Diligence for Cobalt, Lithium, Nickel, and Natural Graphite#

The regulation requires economic operators placing batteries on the EU market to carry out supply chain due diligence for four materials: cobalt, lithium, nickel, and natural graphite. The due diligence framework is aligned with OECD guidelines and requires identifying and mapping the supply chain to the point of origin, assessing risks of human rights violations and environmental harm, and developing a management plan to address identified risks. This applies from August 2025. The geographic concentration of these materials — cobalt largely from the DRC, lithium from the lithium triangle, natural graphite overwhelmingly from China — means most battery supply chains will face material due diligence risk. Audits and third-party verification will be required for higher-risk supply chains.

The Battery Passport: What Manufacturers Must Prepare#

From February 2027, EV batteries and industrial batteries must have a digital battery passport — a unique identifier linked to a data record containing information on chemistry, carbon footprint, recycled content, due diligence reports, and end-of-life information. The passport is accessible via a QR code on the battery and must be readable by operators, regulators, recyclers, and consumers. This requires manufacturers to build data collection and management systems that capture product-level information across the supply chain — not just at the point of final assembly. Portable battery passports follow from August 2027. The data infrastructure required for battery passport compliance is substantial; businesses should begin system planning now rather than waiting for mandatory dates.

• The EU Batteries Regulation (2023/1542) is now in force, bringing carbon footprint declarations, recycled content requirements, and supply chain due diligence for four critical raw materials.
• Any business placing batteries on the EU market — including manufacturers, importers, and distributors — faces new compliance obligations that phase in through 2031.
