Environmental claims about wool: what the law expects

What counts as an environmental claim

An environmental claim is any statement that suggests a product, a material or a brand is better for the environment, or has less impact, than it otherwise would. It can be a word on a hangtag, a sentence on a product page, a line in a newsletter, a social post or a reply to a customer. The rules that govern these claims cover every voluntary, consumer-facing statement a brand makes.

A few terms recur throughout this guide.

• Explicit claims say it in words: “this product is eco-friendly”. They are the most obvious kind, and the first that authorities scrutinise.
• Implicit claims say it without words: images, colours, styling and the layout of a page. A photo of trees beside the line “our products are planet” is an implicit claim about the scale of a product’s benefit, and it must be as accurate as a written one.
• A generic claim uses a broad environmental word, such as “green” or “eco”, without saying, right where the claim appears, what it means and why it is true.
• Substantiation is the evidence behind a claim: the data, certificates or documents that show it is true.
• Greenwashing is making a product or brand look more sustainable than it is. Greenhushing is the opposite reaction: saying nothing about real environmental work for fear of getting a claim wrong.

This guide is written from the Good Wool Collective’s May 2026 session on compliant communication, and from the one-page guidance the Collective prepared for member brands after it. It is general information, not legal advice. No guide can confirm that a particular claim is compliant: that depends on the claim, its context and the evidence behind it, and brands should consult legal counsel about specific claims.
