Greenwashing Rules: Making Claims That Survive Scrutiny
Regulators increasingly require environmental claims to be specific, substantiated and relevant to the actual product impact.
What follows is a practical breakdown for sourcing and development teams, from specification through to verification.

What counts as a claim
Wording, imagery, colours and labels can all communicate an environmental message, including implicit symbols.
In practice the goal is predictability: the same result on the first order and on the fifth reorder.
Substantiation expectations
Each claim needs evidence covering the whole product lifecycle, not a favourable stage only.
Where a standard exists, name the standard number, since a value without a method cannot be verified by a third party.
- Ask for a separate price line for the requirement
- Confirm minimum quantities before committing the colourway
- Build one extra approval round into the calendar
Vague terms to avoid
Generic words such as eco-friendly, green and sustainable require qualification to be defensible.
Plan a trial run before the main order so the settings can be validated on real production equipment.
Comparative claims
Comparisons must be fair, current and clear about what is being compared.
Compare results before and after the intended care regime, since performance often changes after the first wash.
- Confirm the numeric range and the test method in the specification
- Keep an approved physical standard at the machine
- Retest after the agreed care regime before shipping
Practical discipline
Keep a claim file with certificates, test reports and calculations supporting everything printed or published.
Discuss the minimum order quantity with the yarn or process supplier before committing the style to the range.
Summary
A clear specification, a trained operator and a documented test together remove most of the risk from this part of the programme.
