New EU Rules on Environmental Claims: What Material Buyers Should Know

From 27 September 2026, EU member states apply new consumer-protection rules that restrict generic environmental claims and bar displaying sustainability labels not backed by a certification scheme. They target sellers of consumer products, but reach up the supply chain: if you cannot substantiate a material claim, you need documentation from whoever supplied it.
What is actually changing?
The change comes from Directive (EU) 2024/825, adopted on 28 February 2024, which amends the EU’s existing unfair commercial practices rules. Member states had to adopt and publish national implementing measures by 27 March 2026 and must apply them from 27 September 2026. Two provisions matter most to anyone specifying materials. Generic environmental claims — those made without a clear and prominent qualification on the same medium — become prohibited unless the trader can demonstrate recognised excellent environmental performance relevant to the claim. And displaying a sustainability label is prohibited unless it is based on a certification scheme or established by public authorities. In short, a self-issued badge is no longer a safe way to communicate.
Why does this reach material buyers?
The obligation sits with the party making the claim to the consumer, which is normally the brand. But the evidence for that claim almost always lives further up the chain, with the mill, the converter or the material supplier. A brand that prints a sustainability message on a hangtag needs something behind it, and a purchasing team that accepted a supplier’s word rather than documentation is the weak link. This is why the practical effect of the rules is felt at the sourcing stage, well before anything reaches a shelf. Buyers who already collect certification documents are largely prepared; those who rely on supplier marketing are not.
What should you ask suppliers for now?
Ask for the specific rather than the general. Request the certification covering the material you are actually buying, with the scope and the certificate reference, rather than a company-level claim. Where content is the point — recycled or bio-based share — ask for the percentage for that article and the standard used to verify it — for a fibre such as recycled polyester, that means a recognised recycled-content standard. Ask what the claim covers, since a certificate on a fibre does not automatically extend to a finished, coated or dyed fabric. And keep the documents on file against the order, because being able to produce evidence later is the whole point of the exercise.
How should you write material claims?
The safest direction of travel is specific and qualified. A statement that names what was measured, how much of it there is and who verified it is far more defensible than a sweeping adjective. Saying that a fabric contains a stated share of recycled content certified to a recognised standard tells the customer something checkable. A broad assertion that a product is good for the planet does not, and is exactly the type of language the new rules are aimed at. The same discipline helps commercially, because specific claims are more persuasive to informed buyers anyway.
What is still unsettled?
It is worth separating what is settled from what is not. These consumer-protection amendments are adopted law with a known application date. A separate, more detailed proposal specifically on substantiating green claims has had a far more turbulent path through the EU institutions and its final shape and timing remain uncertain, so it would be unwise to plan around a particular outcome. Ecodesign rules and product-passport requirements for textiles are also still being developed through delegated acts, with dates that have moved more than once. The sensible position is to comply with what is already fixed and to build documentation habits that will serve you whatever follows.
Frequently asked questions
When do the new EU rules on environmental claims apply?
Member states must apply the measures from 27 September 2026, under Directive (EU) 2024/825, which was adopted on 28 February 2024.
Do these rules apply to businesses outside the EU?
They bind traders selling to consumers in the EU. A supplier based elsewhere is affected in practice because its customers need substantiation for claims made in the EU market.
Are our own sustainability labels still allowed?
Displaying a label is prohibited unless it is based on a certification scheme or established by public authorities. Self-issued badges without an underlying scheme are the main casualty.
What documentation should we keep on file?
Keep the certificate covering the specific material and scope, the verified content percentage where relevant, and the standard used, filed against the order.
