Regulation (EU) 2023/1542 requires mandatory carbon footprint declarations for batteries placed on the EU market. Declarations for EV batteries have been required since February 2025, and for rechargeable industrial batteries above 2 kWh since February 2026. Performance class labelling follows in August 2026, with the digital battery passport becoming mandatory in February 2027.

Below280 produces compliant battery carbon footprint studies for manufacturers globally, combining rigorous LCA methodology with genuine technical knowledge of battery systems and chemistry.

Why manufacturers come to us

Battery carbon footprint declarations are not standard LCA work. The regulation ties the carbon footprint directly to battery performance parameters: cycle life, useable energy capacity, depth of discharge, state of health at end of service life. Getting those inputs right requires both LCA expertise and a genuine understanding of battery engineering: how cells are designed, how performance parameters are determined, and how the chemistry affects end-of-life options.

Our team includes chemical engineers with direct experience in battery technologies, including solid-state batteries and grid-scale storage systems. We also draw on electrical engineering expertise from Decerna Group, of which Below280 is a commercial spin-out, providing us with practical knowledge of MW-scale battery deployment. That combination allows us to work credibly across the full range of chemistries and applications covered by the regulation, from consumer and EV batteries through to large-format industrial and grid-scale systems.

We build parameter-based models. Once your study is complete, you have a working tool rather than a static report. Change a component supplier, adjust your manufacturing location, or evaluate a new cell chemistry, and the model shows you the carbon consequence. For manufacturers making technology decisions alongside compliance decisions, that is worth having.

EU Battery Regulation carbon footprint compliance timeline

Declarations for EV batteries have been required since February 2025, and for rechargeable industrial batteries above 2 kWh since February 2026. Performance class labelling arrives in August 2026, and the digital battery passport becomes mandatory in February 2027, drawing directly on the carbon footprint data declared earlier in the process.

A compliant study requires primary manufacturing data from your supply chain, a detailed carbon footprint model built to the EU Environmental Footprint method, and third-party verification by a notified body. That process takes two to four months. Manufacturers who have not yet begun will want to move quickly.

What a battery carbon footprint declaration covers

The carbon footprint must be calculated from raw material extraction through to end-of-life recycling, excluding the use phase, using the Circular Footprint Formula for end-of-life modelling. Manufacturing data must be primary and company-specific. A formal Data Quality Rating must be reported alongside the result.

The functional unit depends on battery type. Cycling batteries are assessed against total energy delivered over service life. Backup and on-demand batteries use a different basis entirely. The classification affects the entire structure of the study and needs to be established correctly before data collection begins.

For manufacturers of emerging chemistries, including solid-state and sodium-ion batteries, there are additional considerations. Default recycling models in the regulation do not cover all chemistries, and novel manufacturing processes mean primary data takes longer to collect and justify. Early engagement with the methodology makes a significant difference to how smoothly the study runs.

Battery carbon footprint consultancy from Below280

Below280 can work with battery manufacturers wherever they are based. Our studies are built in openLCA using datasets from the Life Cycle Data Network (LCDN) on the European Platform on LCA, the primary source of EF-compliant datasets specified under the regulation, supplemented by ecoinvent where appropriate.

We manage the full process: scoping, data collection, modelling, documentation, and coordination with the verifier. We work closely with your engineering and supply chain teams, because the quality of a battery carbon footprint study depends entirely on the quality of the underlying data.

We can support battery carbon footprint declarations across the full scope of the regulation, including EV battery packs, rechargeable industrial batteries and grid-scale storage systems above 2 kWh, and carbon footprint datasets for suppliers reporting to OEM customers ahead of their own compliance deadlines.
