Green claims used to be a question of taste. Overdo it and you got pushback in the comments, and that was usually the end of it. Those days are over. An environmental promise is now a statement with legal consequences, and the check no longer happens only inside your own building.
- A promise without evidence is no longer a marketing mistake. It is an unfair commercial practice.
- Green claims have to point at what was actually measured, not at the feeling of the whole product.
- Self-designed labels and in-house seals are the fastest route to a complaint.
- The evidence has to exist before sign-off, not after the first question.
- A brand with nothing solid to say gains more from silence than from a carefully hedged sentence.

Why environmental promises became a board topic
The European directive on empowering consumers applies from 27 September. Among other things it bans generic environmental statements without recognised evidence, and it bans sustainability labels a company awards to itself. The separate legal act on environmental claims that was once planned has been withdrawn. So there is no new special regime, only sharp consumer law that applies to every single statement.
For a brand that means one thing above all: the checkpoint moves forward. If you have to produce the evidence after publication, you asked the question too late. The full text is available at EUR-Lex, and the passages on statements and labels are shorter than the respect for them suggests.
What green claims trigger legally
Green claims move the burden of proof inside the brand. A statement has to refer to a concrete, measurable part of the product or the process, and it must not sound as though it covers the whole. A shirt made from recycled cotton is not a sustainable shirt, and a climate neutral delivery without an explanation of the method is not a statement but an assertion.
In practice that changes how a company works. Buying, quality, legal and marketing all need the same number in front of them before anyone picks a wording. Why this is particularly hard in fashion comes down to the rhythm of the collections, which I described in seasonal logic.
What carries a statement before sign-off
Green claims rarely fail on intent. They fail on procedure. Five rules keep the process clean:
- Fix the reference. Does the statement cover a material, a product, a collection or the company? If you do not say, you have implicitly said all of it.
- Source before wording. Evidence first, text second. The other way round creates a promise the number has to chase.
- No in-house seals. A label you designed yourself is a risk without independent verification, and it also looks cheap.
- Disclose comparisons. Better than what, measured how, over what period? Without those three, a comparison is useless.
- Document the route. Who signed off and on what basis has to be reconstructable a year later.
These rules are not an invention of the legal department, as the practice of the consumer authorities shows. How the directive works in daily life is something I wrote up in more detail in the EmpCo directive.
Where green claims damage a brand
The obvious damage is the complaint. The more expensive one is the retreat. When a brand quietly drops a promise from its communication, its own staff notice first, and they read it as a signal that the promise was never solid.
The second kind of damage comes from caution. Fear of getting it wrong pushes companies into hints, and hints are worthless for a brand. Green claims are not a communication task in that situation. They are a product task. If nothing has changed, say nothing.
My position on this is uncomfortable but it has held: one provable promise carries a brand further than five vague ones. It simply costs more, because it requires real decisions in the product first, and those decisions are almost always made outside marketing.
