Good Wool CollectiveEnvironmental Claims
Why environmental claims about wool need care
Communicating about materials and their properties is becoming increasingly regulated and scrutinised. Brands often struggle to know what is allowed, what is credible, and what risks crossing the line into greenwashing. Wool has many valuable properties, among them breathability, durability, odour resistance and warmth, but communicating these benefits is becoming more complex.
Three legislative frameworks now shape sustainability communication: the EU’s Empowering Consumers for the Green Transition Directive (ECGT), the UK’s Digital Markets, Competition and Consumers Act with its Green Claims Code, and the US Federal Trade Commission’s Green Guides. Their timelines differ, but their objective is the same: protecting consumers from misleading or vague sustainability claims. Claims must be clear, accurate and substantiated, important information cannot be left out, certifications must be used correctly, and generic terms such as “eco”, “green” or “sustainable” should be avoided.
Compliance is no longer only about wording; it is also about the overall impression a consumer takes away, from the images as much as the text. The stronger the claim, the stronger the evidence it needs. Claims about the wool fibre differ from claims about the finished product, and regenerative claims are among the hardest to make, because the term has no single agreed definition. What follows is general guidance, not legal advice.
Key takeaways for brands
- Read each claim as an average consumer would. Ask whether it could lead them to a decision they would not otherwise make; consumer perception is the test authorities are expected to apply.
- Drop vague terms. “Conscious”, “responsible” and “ethical” are best avoided even with an explanation, and “eco-friendly” or “sustainable” used only with evidence; the safest course is to avoid them all.
- Keep fibre claims and product claims apart. “Wool is a renewable fibre” states a documented fact; “this garment is biodegradable” or “lasts ten years” is a claim about the finished product, which may need evidence.
- Match your evidence to the strength of the claim. For a mulesing-free claim, ask your suppliers for transaction certificates that cover every step at which wool could have been mixed, tied to the lot used. This is the safest basis; the law sets no fixed threshold.
- Have the team that owns your environmental work check the facts before the copy is written, and again before it is published.

Defining Compliant Communication Guidelines
This session explores the current EU, UK, and US regulatory landscape around green claims and what it means for brands communicating about wool. Compliance expert Emma Covi and author Lucianne Tonti join host Lisa Bergstrand to unpack which wool properties can be stated compliantly, how to use certifications like the Responsible Wool Standard, and how to navigate the still-uncharted territory of regenerative claims — without falling into greenwashing or greenhushing.
