# EU Batteries Regulation: evidence pack for carbon footprint and recycled content targets

What to keep for EU Batteries Regulation Article 7 carbon-footprint declarations and Article 8 recycled-content documentation, with covered battery categories and source-linked evidence fields.

*EU Batteries Regulation* *Evidence file* *Articles 7 and 8*

## Carbon footprint and recycled content evidence for EU battery models

Build one evidence file that separates Article 7 carbon-footprint declarations from Article 8 recycled-content documentation.

The useful split is category, model, manufacturing plant, calculation method, input data, technical documentation, and supplier evidence.

Article 7 and Article 8 of Regulation (EU) 2023/1542 are not generic sustainability claims. They require battery-model evidence tied to specific battery categories, manufacturing plants, technical documentation, calculation methods set by delegated acts, and the materials or carbon values being declared.

## Start with the covered battery category

For Article 7, the carbon-footprint track applies to electric vehicle batteries, rechargeable industrial batteries with a capacity greater than 2 kWh, and light means of transport (LMT) batteries. The evidence file should identify the battery model, the manufacturing plant, the battery category, and whether any external-storage distinction matters for the industrial-battery cohort.

For Article 8, the recycled-content track is different: it covers industrial batteries with a capacity greater than 2 kWh, electric vehicle batteries, SLI batteries, and LMT batteries where the article applies, but only when the battery contains cobalt, lead, lithium, or nickel in the relevant active materials or battery content. Do not apply Article 7 and Article 8 as one combined checklist.

- Article 7 category field: electric vehicle battery, rechargeable industrial battery greater than 2 kWh, LMT battery, or out of Article 7 scope.
- Article 8 category field: industrial battery greater than 2 kWh, electric vehicle battery, SLI battery, LMT battery, or out of Article 8 scope.
- Plant field: manufacturing plant used for the declaration or recycled-content record.
- Model field: battery model identifier matching the EU declaration of conformity and technical documentation.
- Material trigger field: whether cobalt, lead, lithium, or nickel is present in the Article 8-relevant materials.

- [Regulation (EU) 2023/1542 on batteries and waste batteries](https://eur-lex.europa.eu/eli/reg/2023/1542/oj/eng?ref=sorena.io) - Article 8 identifies the recycled-content categories and ties them to cobalt, lead, lithium, and nickel content.

## Article 7 carbon-footprint declaration evidence

The Article 7 declaration is made for each battery model per manufacturing plant. The file should preserve the manufacturer administrative details, model details, manufacturing-plant location, total carbon footprint, life-cycle-stage breakdown, EU declaration of conformity identification number, and the public link to the supporting carbon-footprint study.

Carbon-footprint classes and maximum life-cycle carbon-footprint thresholds should only be filled when the relevant delegated or implementing act and format are available for the battery category. Until then, keep a controlled status value such as 'awaiting applicable delegated act' rather than inventing a class boundary or threshold.

- Declaration record: model, plant, manufacturer, battery category, expected-service-life denominator, and kg CO2e per kWh value.
- Life-cycle record: carbon footprint split by the life-cycle stages required by the Article 7 methodology.
- Public-study record: public version link, publication status, version, and any redactions from the technical study.
- Class record: performance class, label format, and threshold source only after the applicable delegated or implementing act supports them.
- Exception record: whether the battery was already placed on the market or put into service before preparation for re-use, repurposing, or remanufacturing.

## Build a model-level batteries evidence file

Use the Article 7 and Article 8 split to align engineering, procurement, sustainability, and conformity evidence before declarations, labels, or supplier claims are approved.

## Article 8 recycled-content documentation evidence

Article 8 starts as documentation about recovered-material shares before it becomes a minimum-share technical-documentation requirement. The documentation should show the percentage share of cobalt, lithium, and nickel in active materials recovered from battery manufacturing waste or post-consumer waste, and the percentage share of lead present in the battery recovered from waste.

The minimum-share rows should be kept separately from the disclosure rows. For the grounded Article 8 thresholds, the file can record 16 percent cobalt, 85 percent lead, 6 percent lithium, and 6 percent nickel for the earlier minimum-share step, and 26 percent cobalt, 85 percent lead, 12 percent lithium, and 15 percent nickel for the later step. Do not add other materials unless a delegated act adds them.

- Recovered-content input record: supplier, waste source type, material, active-material link, mass basis, and supporting certificate or batch record.
- Calculation record: model, year, plant, calculation file, methodology source, reviewer, and locked data version.
- Minimum-share record: cobalt, lead, lithium, and nickel values tracked separately from voluntary recycled-content claims.
- Supplier evidence record: contractual data rights, chain-of-custody evidence, recycled-source statement, and change-notification trigger.
- Delegated-act watch record: methodology, verification format, added materials, and any revised targets only when the source supports them.

- [Regulation (EU) 2023/1542 on batteries and waste batteries](https://eur-lex.europa.eu/eli/reg/2023/1542/oj/eng?ref=sorena.io) - Article 8 sets the first minimum recycled-content shares for cobalt, lead, lithium, and nickel in covered battery categories.

## Technical documentation and conformity assessment file

Annex VIII makes Articles 7 and 8 a technical-documentation problem, not just a sustainability-reporting problem. For Module D1, the technical documentation should include the carbon-footprint study, the recycled-content study, the calculations made under the applicable delegated-act methodology, and the evidence and information determining the input data.

The quality system should document how the manufacturer monitors the parameters and data needed to calculate and update recycled-content shares and, where applicable, carbon-footprint values and classes. A notified body can check the reliability of that data and the implementation of the calculation methodology.

- Technical-documentation index: general battery description, intended use, label specimen, applied standards or specifications, calculations, documentary evidence, carbon-footprint study, recycled-content study, and test reports.
- Quality-system procedure: data owner, source system, supplier input, calculation frequency, review control, approval control, and change control.
- Notified-body readiness: evidence pack showing data reliability, calculation methodology implementation, and links between source data and declared values.
- Retention control: keep the technical documentation available to national authorities for 10 years after the battery has been placed on the market.
- EU declaration link: ensure the battery model in the declaration, technical documentation, and Article 7 or Article 8 evidence file is the same model.

## Supplier evidence that should survive audit

Supplier evidence should be collected at the same granularity as the legal evidence: battery model, manufacturing plant, material stream, year, and calculation version. A generic supplier sustainability letter is weak support if it cannot be traced to the cobalt, lead, lithium, nickel, or carbon-footprint input used in the calculation.

For carbon footprint, supplier data should connect upstream materials, manufacturing inputs, plant allocation, and life-cycle-stage values to the Article 7 study. For recycled content, supplier data should connect recovered material to battery manufacturing waste or post-consumer waste, then to the Article 8 percentage calculation.

- Require supplier declarations to name the supplied material, shipment or batch, model or bill-of-materials link, waste-origin category, and calculation period.
- Keep evidence of changes in chemistry, plant location, process energy, recycled-content source, or supplier chain because those changes can alter declared values.
- Reject evidence that only says 'recycled', 'low carbon', or 'sustainable' without the data needed for the Article 7 or Article 8 calculation.
- Keep supplier records with the technical-documentation index so product compliance, quality, and sustainability teams use the same evidence set.
- Flag gaps where the applicable delegated-act methodology has not yet provided the calculation or verification format needed for a category.

## Delegated acts and claims to avoid

The evidence file should distinguish binding Batteries Regulation text, adopted delegated acts, draft or technical-support material, and internal assumptions. Article 7 expressly depends on delegated and implementing acts for calculation methodology, declaration format, performance classes, label formats, and maximum life-cycle carbon-footprint thresholds.

Article 8 also depends on a delegated act for the calculation and verification methodology and documentation format for recovered-content shares. Until the relevant source is available in the evidence set, the page should not state ungrounded class thresholds, category-specific formats, or extra recovered-material targets.

- Do not state a carbon-footprint performance class unless the applicable class source exists for the category.
- Do not state a maximum life-cycle carbon-footprint threshold unless the threshold source exists for the category.
- Do not use recycler recovery-efficiency rules as a substitute for Article 8 recycled-content methodology.
- Do not publish battery-level recycled-content marketing claims from supplier letters unless they reconcile to the Article 8 model, year, plant, and material calculation.
- Do not hide whether a source is a Commission technical-support report, a JRC methodological support item, an adopted delegated regulation, or the binding Batteries Regulation.
