EU Green Claims Directive Proposal Claim substantiation evidence workflow

A practical workflow for turning a planned EU consumer-facing environmental claim into a substantiation file before it is published, printed, reused, or sent for verification.

Use it to separate proposal status, claim wording, scope boundaries, scientific support, life-cycle relevance, comparison rules, carbon-credit disclosures, consumer communication, approval status, and review triggers.

Overview

The Green Claims file should start with one caution: the source material describes a legislative proposal and negotiating texts, not a fully enacted Green Claims Directive. The grounded workflow below is therefore designed for claim governance and preparation. It starts with the exact public claim, checks whether the proposal would apply, and tests whether the trader can support the claim's scope, method, data, life-cycle relevance, comparison basis, carbon-credit position, verification route, and consumer-facing explanation before the claim is used.

Section 1

1. Confirm proposal status, claim scope, and applicability

First record the legal status you are working from. The Commission proposed COM(2023) 166 final on 22 March 2023, Parliament adopted its first-reading text on 12 March 2024, the Council approved a general approach on 17 June 2024, and the OEIL procedure file in the grounding record listed the file as awaiting the Council's first-reading position. Do not convert those proposal milestones into final legal deadlines unless a final adopted act is available in the source set.

Then capture the consumer-facing wording exactly as it will appear on a package, page, label, ad, sales deck, marketplace listing, QR-code landing page, or in-store material. Record who generated the claim, where it will be used, whether it concerns a product, part of a product, the trader, or a specific activity, and whether another EU rule already sets the substantiation, communication, labelling, or verification method for that claim.

Status entry: source checked, procedure stage, proposal text used, Council or Parliament changes relied on, and whether any final adopted Green Claims Directive text is available to the team.
Capture the claim verbatim, including icons, labels, brand names, ratings, scores, QR links, footnotes, and nearby qualifying text.
Classify the claim type: written or oral explicit environmental claim, product claim, trader claim, comparative claim, future-performance claim, climate claim, carbon-credit claim, environmental label, or aggregated environmental score.
Define the boundary: whole product or part, whole life cycle or specific stage, all trader activities or named activity, and EU market where the claim is communicated.
Check for a sector-specific EU rule first; the Green Claims proposal is framed as a safety net where specific EU substantiation or communication rules do not already govern the claim.
Stop or rewrite the claim if it is too broad to substantiate as written, such as an unqualified general environmental benefit claim without a clear environmental characteristic.

Section 2

2. Build the substantiation file around quality, relevance, and boundaries

For each claim, create a substantiation file that ties the wording to recognised scientific evidence, accurate information, relevant methods or international standards, and the specific environmental characteristics being claimed. The file should explain why those characteristics are significant for the product or trader from a life-cycle perspective, not just convenient because the data is easy to collect.

Use primary company-specific information where available for the characteristics subject to the claim. Where primary information is not available, record the secondary information used, why it is representative of the value chain, and the quality checks applied. If evidence is uncertain, contested, stale, or unavailable for a significant impact, narrow the claim, switch to factual performance reporting, or hold it.

Evidence fields: claim ID, final wording, product or trader boundary, environmental characteristics, method or standard, primary data owner, secondary data source, assumptions, limitations, and version date.
Quality checks: recognised scientific basis, data accuracy, representativeness, calculation owner, source traceability, and whether the evidence can be explained clearly to consumers and competent authorities.
Scope checks: whether the claim covers the whole product or only a component, all activities or a defined activity, the whole life cycle or a named stage, and whether any legal minimum already requires the performance.
Relevance checks: whether the claimed characteristic is significant for the product or trader and whether other significant environmental aspects or impacts have been omitted.
Hold triggers: no primary or representative secondary data for the claimed characteristic, no method owner, unsupported extrapolation across product variants, hidden legal-minimum performance, outdated calculations, or claim wording that is broader than the evidence.

Section 3

3. Test life-cycle impacts and trade-offs before approving the wording

A claim about one environmental benefit can mislead if it hides significant impacts elsewhere. The workflow should therefore check the life-cycle stages and impact categories that are relevant to the claim, then document why the claim does or does not need a full life-cycle assessment.

For claims based on Product Environmental Footprint, Organisation Environmental Footprint, PEFCRs, OEFSRs, or another accepted method, keep the functional unit, reference flow or product portfolio, system boundary, data sources, impact categories, hotspot interpretation, assumptions, and limitations with the claim file. For narrower claims, keep the rationale for using a narrower assessment and the checks performed to avoid burden shifting.

Identify relevant life-cycle stages: raw materials, production, distribution, use, end of life, and transport where they matter to the claim.
Identify relevant impact categories or aspects: climate, water, resource use, land use, toxicity, eutrophication, recyclability, recycled content, durability, repairability, biodiversity, waste prevention, or the specific characteristic claimed.
Check for trade-offs: a benefit in one impact category, product component, or life-cycle stage should not create significant harm or hide a material worsening elsewhere.
For footprint-style claims, record the functional unit, reference flow, system boundary, inventory data, impact-assessment method, hotspot interpretation, sensitivity checks, and reviewer notes.
For claims that do not need a full life-cycle assessment, document why the claim is limited to a single characteristic and how other significant impacts were screened.

Section 4

4. Add special gates for comparisons, carbon credits, and environmental labels

Comparative claims need their own evidence gate because the comparison can fail even when the trader's own data is strong. The compared products or traders should serve a similar purpose or be in the same product group or sector, the method and data should be equivalent, the relevant value-chain stages should be equivalent, and assumptions should be set consistently.

Climate and carbon-credit claims also need a separate gate. Directive (EU) 2024/825 prohibits product claims that, based on offsetting greenhouse gas emissions, state that a product has a neutral, reduced, or positive greenhouse-gas impact. The Council Green Claims text separately addresses climate-related trader claims, carbon credits, contribution claims, and offset claims, and calls for separate information on greenhouse gas emissions, reductions, future performance, and carbon credits where applicable.

Comparative-claim file: compared product or trader, same product group or sector, similar purpose or functional properties, method used, equivalent data sources, equivalent value-chain coverage, equivalent impact coverage, assumptions, and baseline year.
Improvement-claim file: evidence that the improvement is significant, achieved in the relevant period, tied to a stated baseline year, and checked for effects on other relevant environmental characteristics.
Carbon-credit file: total emissions, reductions, future performance where claimed, quantity of credits in tCO2e, whether credits are reductions or removals, share of emissions addressed by credits, verification or certification scheme, registry, and whether the claim is a contribution or offset claim.
Environmental-label file: scheme owner, criteria, award method, public information, stakeholder or expert basis, complaint mechanism, verification status, and whether the trader's claim matches the certified characteristics.
Aggregated-score gate: do not use a single environmental score or rating unless the aggregation basis is supported by applicable EU or national rules and is explained transparently to consumers.
Directive 2024/825 gate: flag any generic environmental claim, whole-product or whole-business claim, sustainability label, future-performance claim, or product offsetting claim that may already be restricted under the amended UCPD rules.

Section 5

5. Approve, publish, retain, and reopen the record

Approval should be a release gate, not a loose legal sign-off. The record should show who approved the final wording, what evidence was approved, whether the Council-text route would require third-party verification or Specific Technical Documentation, what consumer-facing substantiation summary is available, and when the claim must be reviewed.

The Council text provides review triggers that are useful operational controls: review the information when circumstances may affect claim accuracy and no later than five years from the certificate of conformity or relevant Specific Technical Documentation date. Reopen earlier when the product, supplier, method, data source, legal rule, claim wording, packaging, comparison set, carbon-credit position, verifier certificate, or consumer-facing summary changes.

Approval record: final claim text, channel, product or trader boundary, approved evidence package, approver names, verifier status where applicable, publication date, and withdrawal owner.
Consumer-facing record: a clear substantiation summary, the environmental characteristics covered, product-use instructions when the use phase is relevant, the certificate of conformity and verifier contact where applicable, and links or data carriers placed next to the claim where required.
Retention record: final creative, translations, calculations, studies, test reports, supplier data, standards, assumptions, limitations, verifier certificate, Specific Technical Documentation where applicable, and change log.
Review triggers: new product version, supplier or material change, updated method or standard, new comparative product set, new or changed carbon credits, data-quality issue, authority challenge, complaint, or any circumstance affecting accuracy.
Withdrawal triggers: the public wording is broader than the evidence, evidence cannot be produced, a certificate is withdrawn or expires, the claim becomes inaccurate, or a competent authority requires corrective action.
