EU Green Claims Directive 2026: What Suppliers Need to Prepare Now

What Is the EU Green Claims Directive?

The EU Green Claims Directive is an EU regulation targeting unsubstantiated environmental marketing claims. Passed by the European Parliament in March 2024, it requires any company making a claim about the environmental benefit of its products or services to back that claim with verified, scientific evidence — or face enforcement action.

Member states are expected to transpose it into national law and begin enforcement from 2026 onward. For suppliers, this affects far more businesses than CSRD does — because it targets marketing claims rather than reporting thresholds.

Which Types of Claims Will Be Banned Without Evidence?

The directive specifically targets vague, generic, or unverifiable environmental claims. Banned without supporting evidence:

• "Carbon neutral" or "net zero" — unless based on a full lifecycle assessment with independently verified offset portfolio
• "Climate positive," "climate friendly," or "carbon friendly" — without quantified data
• "Eco-friendly," "natural," "green," or "environmentally responsible" — too vague to be verifiable
• "Made with recycled materials" — without stating the percentage and the recycled content standard used
• Future claims such as "we are working towards carbon neutrality" — only permitted if backed by a credible, time-bound, publicly available reduction plan
• Carbon offset claims referencing schemes that lack minimum transparency (Article 6 Paris Agreement quality level or equivalent)

How Does This Affect Suppliers Specifically?

If any of the following appear in your sales materials, product packaging, tender responses, or website, you are in scope:

• Describing your packaging as "sustainable" in a procurement tender document
• Including "low carbon processes" in your company brochure
• Using "green manufacturing" or "eco-production" anywhere in your marketing
• Displaying a generic self-created "green" or "eco" badge on your product
• Writing "we are committed to the environment" in your supplier profile without any substantiation

The directive applies at the point of making the claim — not just to large companies. A 30-person supplier claiming "sustainable logistics" in a Coupa tender faces the same legal exposure as a listed company.

What Evidence Satisfies the Directive for Carbon Claims?

The lowest-barrier substantiated claim is "we measure and report our full Scope 1, 2, and 3 carbon footprint annually using the GHG Protocol." A Carbon Passport from DeCarbonOPS provides exactly this evidence — without requiring an external audit.

What Are the Penalties for Non-Compliance?

The directive empowers national enforcement authorities (consumer protection agencies or environmental regulators) to:

• Issue fines of up to 4% of annual national turnover for the infringement period
• Require immediate removal of non-compliant claims from all channels (website, packaging, sales materials)
• Apply temporary sales restrictions in serious cases
• Publish company names in public enforcement registers

For a supplier with €5 million annual turnover, a 4% fine is €200,000. The cost of substantiating claims with a Carbon Passport — free for the first annual report — is not a meaningful comparison.

What Should Suppliers Do Before 2026?

A practical action plan to be directive-ready:

• Audit all marketing materials — identify every environmental claim currently in use
• Measure your emissions — get a Carbon Passport as your baseline evidence. Do this now; you need at least one year of data before you can make a comparative "reduced" claim
• Remove all unsubstantiated claims immediately — replace "eco-friendly supplier" with "we measure our full GHG footprint annually using the GHG Protocol"
• Document your methodology — DeCarbonOPS records your inputs, DEFRA 2023 factors, and calculation method automatically
• Build a year-over-year baseline — the companies best positioned in 2026 are those who started measuring in 2024–2025 and can show a verified reduction trend

The directive rewards companies that are measurable and transparent — not necessarily companies with the lowest carbon footprint. A supplier with 150 tCO2e who measures it annually and publishes the methodology is more compliant than a supplier claiming to be "green" without any data. Get started free.
