This article covers the product carbon footprint (PCF) of a battery, the declaration, the performance classes and the passport fields that carry the result. It does not compare tools. ## What Regulation 2023/1542 requires per battery category and when The duty sits with the producer, meaning whoever first places a battery on the EU market under their own name or trademark, whether they manufacture the cell or import a finished pack. Four categories carry different dates: EV batteries, rechargeable industrial batteries above 2 kWh, LMT batteries (light means of transport, so e-bikes and scooters), and portable batteries. | **Category** | **Carbon footprint declaration** | **Performance class** | **Maximum threshold** | **Battery passport** | | --- | --- | --- | --- | --- | | EV batteries | 18 Feb 2025 | 18 Feb 2026 | 18 Feb 2028 | 18 Feb 2027 | | Rechargeable industrial, above 2 kWh | 18 Feb 2026 | 18 Feb 2027 | 18 Feb 2029 | 18 Feb 2027 | | LMT batteries | 18 Feb 2028 | 18 Feb 2029 | 18 Feb 2030 | 18 Feb 2027 | | Portable | Not required | Not required | Not required | Not required | Every one of these dates is written in the regulation as "or 12 to 18 months after the relevant delegated act enters into force, whichever is later". The delegated acts on the calculation methodology are the real trigger, and they have slipped before. My position on the sequence: the passport date gets the attention and is the least demanding of the three. Publishing a number in 2027 is data plumbing. Landing in a defensible performance class, and staying under a threshold that tightens on a schedule, is a sourcing programme with a multi-year lead time. The passport is also the first of the EU's [digital product passports](https://www.fiegenbaum.solutions/en/blog/digital-product-passport-from-european-regulation-to-global-standard?hsLang=en). ## Which methodology counts: PEF, ISO 14067 and EN IEC 63372 Three layers sit on top of each other. ISO 14067:2018 defines product-level carbon footprint quantification in general terms. EN IEC 63372 applies it to batteries: mandatory lifecycle stages, allocation on shared production lines, treatment of formation and testing energy. The binding layer for the declaration is the Commission's PEF-based methodology in the delegated act, and where PEF and ISO differ, PEF decides the declared figure. What moves that figure is rarely the database. It is allocation. **A worked example, illustrative arithmetic rather than a benchmark:** a 60 kWh pack with a cradle-to-gate footprint of 3,900 kg CO2e declares 65 kg CO2e/kWh, and its cathode carries a 30 percent recycled nickel share. Under cut-off allocation the recycled fraction bears only collection and reprocessing burdens, and the figure drops to roughly 59. Under a rule that shares the original primary production, the same physical pack declares around 64. Nothing changed in the factory, and six kilograms per kWh decides which side of a class boundary it lands on. Two allocation decisions recur: co-products in mining, where cobalt is largely a by-product of nickel and copper and economic allocation needs its price source documented, and recycled content, where cut-off is the rule and the chain of custody is the proof. Document the reasoning, or a verifier substitutes their own. My [LCA implementation guide](https://www.fiegenbaum.solutions/en/blog/mastering-life-cycle-assessment-steps-software-and-impact-analysis?hsLang=en) covers the modelling side of the same workflow. ## Collecting the supplier data the declaration needs Database averages produce a number, not a competitive one: a supplier-specific figure from a hydro-powered cell plant beats a continental average every time. Site matters more than headquarters here, because two plants of the same manufacturer on different [grids](https://ember-energy.org/latest-insights/european-electricity-review/) declare materially different numbers. Send tier-1 cell and cathode suppliers a field list, not a questionnaire: - Activity data per functional unit: mass of each material input and process energy in kWh, per production site - Electricity attribution: grid mix by country, on-site generation and any [certificates](https://www.fiegenbaum.solutions/en/blog/reducing-scope-2-emissions-energy-attribute-certificates-eacs?hsLang=en) claimed, with their temporal granularity - Recycled content share per material, with the chain of custody evidence behind it - A data quality rating per dataset: measured, calculated or estimated, with the reference year - Verification status: unverified, internally reviewed or third-party verified, and by whom The last two fields are the ones companies skip and the first ones a verifier opens. ## What battery passport software does, and where the data work stays with you Having designed ESG software myself, I can draw the boundary that vendor pages structurally cannot publish. | **What a passport tool genuinely produces** | **What you still have to produce** | | --- | --- | | The data model, versioning, the unique identifier, the QR code and the access layers | The values that go into those fields, and the decision on what is true | | Carrying a declared PCF figure into the passport and keeping it auditable | Calculating that figure and defending the allocation rules behind it | | Supplier templates, reminders and a collection workflow | Getting tier-1 suppliers to release site-level primary data at all | | Assembling the evidence pack for a verifier | The verification, and the remediation when it fails | Software shortens the second reporting cycle and every one after it. It does not shorten the first, because the first cycle is where the data does not exist yet. ## Where carbon footprint declarations go wrong **Recycled content asserted rather than evidenced.** A share claimed in the passport without a chain of custody behind it is the fastest way to fail verification, and it is visible to anyone scanning the QR code. **Claims that outrun the declaration.** Marketing reaches for "low-carbon" while the declaration says class B. A comparative environmental claim needs the same methodology on both sides, and the passport record is the evidence a regulator reads first. State the class and the figure, link the passport, stop there. ## Frequently asked questions What is the difference between battery EPR obligations and the battery passport? EPR covers collection, treatment and recycling once a battery is waste, enforced nationally through registers and take-back schemes. The passport is a product-level data record for a battery still on the market. Who counts as a producer under Regulation (EU) 2023/1542? Whoever first places the battery on the EU market under their own name or trademark, per member state. Importers and own-brand resellers are producers although they never manufactured a cell. When exactly does the carbon footprint declaration apply per battery category? See the table above. The applicable date is the later of the calendar date and 12 to 18 months after the relevant delegated act, so the act sets your deadline. What happens if the declared carbon footprint exceeds the maximum threshold? The battery may no longer be placed on the EU market in that configuration. The performance class is a competitive signal, the threshold is a market access condition. Does buying compliance software make me compliant? No. A tool stores, formats and publishes a declaration. The primary data, the methodology choice and the verification stay with the producer. Do I need separate software for the battery passport and for EPR reporting? Usually yes, they are different data objects. EPR reporting is tonnage by member state and scheme, the passport is per product model and harder to retrofit.
