# Verifier workflow under the EU Green Claims Directive

FAQ on the proposed EU Green Claims verifier workflow: substantiation, ex-ante verification, verifier requirements, certificates, and proposal-stage caveats.

*FAQ* *Green Claims* *EU*

## EU Green Claims Directive Verifier workflow

What the proposed Green Claims verifier workflow would require before a business uses an explicit environmental claim.

This FAQ separates grounded proposal text from final-law certainty and focuses on substantiation, verifier checks, certificates, and retained records.

The Green Claims file is still grounded here as a legislative proposal and Council general approach, not as final law. For ordinary explicit environmental claims in scope, the proposed workflow is to substantiate the claim first, send it through an independent accredited verifier before public use, and retain the certificate and supporting assessment records.

## What should teams do about verifier workflow under EU Green Claims Directive?

Build the workflow around the claim, not around a generic compliance calendar. The Commission proposal says explicit environmental claims would need substantiation and ex-ante verification before they are used in commercial communications. The Council general approach keeps that structure but changes some drafting, including references to claims being generated by the trader and environmental labels or schemes being made available.

The first gate is therefore scope and claim wording: identify the exact explicit environmental claim, the product or trader it concerns, whether another EU regime already sets specific rules, and whether the claim is ordinary verification or a Council-proposed simplified-procedure case handled through Specific Technical Documentation.

- For ordinary claims, prepare the substantiation assessment before sending the claim to a verifier.
- For Council-proposed simplified-procedure claims, complete the Specific Technical Documentation before the claim is made public.
- Do not describe the workflow as final EU law until the Green Claims Directive is adopted and the final text is checked.

Sources for this answer:

- [Council general approach on the Green Claims Directive](https://data.consilium.europa.eu/doc/document/ST-11312-2024-INIT/en/pdf?ref=sorena.io) - Council Article 10 keeps verification before an explicit environmental claim is generated and Article 3a describes a proposed Specific Technical Documentation route for certain claims.
- [Commission proposal for the Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A52023PC0166&ref=sorena.io) - The Commission proposal describes substantiation and third-party verification before claims are used in commercial communications.

## What should go into the substantiation dossier before verification?

The verifier workflow starts with a substantiation file that can be checked against the proposed requirements. For ordinary explicit environmental claims, the Commission proposal says the assessment should rely on recognised scientific evidence and state-of-the-art technical knowledge, identify significant impacts from a life-cycle perspective, cover relevant environmental aspects, state whether the claim applies to the whole product or trader or only part of it, address legal-baseline claims, trade-offs, offsets where relevant, and use accurate primary or secondary information.

For comparative claims, the dossier should also show that compared products or traders use equivalent information, data generation or sourcing, value-chain coverage, impact coverage, and assumptions. If the Council simplified procedure applies, the record is not a full verifier package; it is the Specific Technical Documentation required before the claim is public.

- Claim text and medium where the consumer will see it.
- Product, service, activity, trader, and life-cycle boundary covered by the claim.
- Scientific evidence, data sources, calculations, assumptions, limitations, and trade-off analysis.
- Comparative-claim equivalence evidence where the claim compares products or traders.
- Specific Technical Documentation only where the Council-proposed simplified route applies.

Sources for this answer:

- [Commission proposal for the Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A52023PC0166&ref=sorena.io) - Article 3 explanation lists the substantiation criteria for explicit environmental claims, including scientific evidence, life-cycle significance, trade-offs, offsets, and primary or secondary information.
- [Council general approach on the Green Claims Directive](https://data.consilium.europa.eu/doc/document/ST-11312-2024-INIT/en/pdf?ref=sorena.io) - Council Article 3a adds a Specific Technical Documentation route for listed lower-complexity claims and claims tied to certain other substantiation routes.

## Who can act as verifier, and what does the verifier decide?

Under the proposal, the verifier is not an decision owner. The Commission proposal describes a third-party conformity assessment body accredited under Regulation (EC) No 765/2008. The Council general approach also refers to accredited conformity assessment bodies for verification activities or EMAS environmental verifiers, and adds EN ISO/IEC 17029 compliance.

The verifier checks the nature and content of the claim against the relevant substantiation and communication requirements. If compliance is demonstrated, the verifier issues a certificate of conformity. The certificate supports cross-EU recognition by competent authorities, but it does not prevent national authorities or courts from assessing the claim under the Unfair Commercial Practices Directive.

- Independence: the verifier must be separate from the product, trader, claim, or labelling scheme being checked.
- Competence: the verifier must have suitable expertise, equipment, infrastructure, and qualified personnel.
- Integrity: management and personnel must avoid conflicts and pressures that could affect judgment.
- Output: issue or refuse a certificate of conformity based on the proposed Directive requirements.

Sources for this answer:

- [Council general approach on the Green Claims Directive](https://data.consilium.europa.eu/doc/document/ST-11312-2024-INIT/en/pdf?ref=sorena.io) - Council Articles 10 and 11 set out verifier requirements, certificate issuance, certificate recognition, and the caveat that certificates do not prejudice national authority or court assessments.
- [Commission proposal for the Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A52023PC0166&ref=sorena.io) - Commission Article 11 explanation says the verifier must be accredited, independent, technically competent, and free of conflicts of interest.

## What records should survive the verifier decision?

Keep the record set tied to the verifier decision. For ordinary verified claims, that means the claim version, substantiation assessment, verifier correspondence, certificate of conformity if issued, and consumer-facing summary or link material. The Commission proposal expects claim communication to include substantiation information such as covered aspects, underlying studies and calculations, how improvements are achieved, the certificate, and verifier contact details.

The Council text adds a stronger certificate-management trail: certificates, review certificates, withdrawals, and updates would be communicated through a public interface connected to IMI, with the Commission publishing an up-to-date list on the Single Digital Gateway. Council text also says certificates would be valid for a maximum period of five years and substantiation must be reviewed earlier if circumstances affect claim accuracy.

- Claim version and approved consumer-facing wording.
- Substantiation assessment or Specific Technical Documentation, including studies, calculations, assumptions, and limitations.
- Verifier identity, accreditation basis, conflicts check, decision, and certificate of conformity if issued.
- Certificate updates, withdrawals, review records, and any IMI or Single Digital Gateway record references once the final system exists.
- A proposal-status note so internal teams do not treat Council draft wording as final enacted law.

Sources for this answer:

- [Council general approach on the Green Claims Directive](https://data.consilium.europa.eu/doc/document/ST-11312-2024-INIT/en/pdf?ref=sorena.io) - Council Article 10 describes certificate validity, certificate updates and withdrawals, IMI communication, and publication of certificate lists on the Single Digital Gateway.
- [Commission proposal for the Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A52023PC0166&ref=sorena.io) - Commission Article 5 explanation supports retaining substantiation information, underlying studies, calculations, certificate details, and verifier coordinates with the claim.

## What is not certain yet?

Do not lock implementation dates, forms, or certificate mechanics from this FAQ alone. The cited materials include the Commission proposal and the Council's 17 June 2024 general approach; those are not the final enacted Directive. The final obligations depend on adoption, publication, national transposition, and implementing acts for details such as certificate form and technical issuing or notification procedures.

Teams can still prepare useful records now: map claims, collect substantiation evidence, identify likely verifier inputs, and keep a versioned watchlist of text changes between the Commission proposal, Parliament position, Council general approach, and the final Directive when available.

- Final legal text and article numbers may change.
- The exact certificate form and technical procedure need implementing acts after entry into force.
- National transposition and enforcement setup will matter for live operations.

- [Council general approach on the Green Claims Directive](https://data.consilium.europa.eu/doc/document/ST-11312-2024-INIT/en/pdf?ref=sorena.io) - The Council document is expressly a general approach on a proposal and contains open markers for dates and later implementing acts.
- [Commission proposal for the Green Claims Directive](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A52023PC0166&ref=sorena.io) - The EUR-Lex source is COM(2023) 166 final, a proposal for a directive rather than an adopted directive.
