An independent screen against the CMA's own Code.
Green Claims Audit (UK) reads the environmental claims in your marketing and packaging and tells you which ones are high-risk under UK law — the specific principle each one fails, and a compliant way to say it instead. It is a screening tool, not a law firm.
Built on the CMA Green Claims Code, not on vibes.
The CMA's Green Claims Code (2021) sets out six principles every environmental claim must meet. Read together with the Digital Markets, Competition and Consumers Act 2024 — in force since 6 April 2025 — a claim that fails those principles is one the CMA can act on now, deciding for itself that a business has misled consumers and fining up to 10% of worldwide turnover without going to court.
This tool takes the copy you paste and scores it against a dictionary of the claim patterns the Code singles out — generic environmental words, offset-based neutrality, self-made sustainability labels, unsubstantiated or future-dated claims. Every flag is traced back to the principle it engages and the DMCCA misleading-practices risk. You get a claim-by-claim verdict and a rewrite, as a PDF.
Brands selling to UK consumers.
The Code bites hardest on the everyday claims consumer brands put on packs and in campaigns. This tool is built for the UK marketing, brand, sustainability and packaging leads who write and sign off that copy:
"Natural", "eco", "climate-neutral"
Grocery, food and drink brands whose packs lean on environmental virtue words and neutrality claims — a sector the CMA has flagged directly.
"Conscious", "responsible"
Apparel and footwear brands using sustainability capsules and self-made labels — the subject of the CMA's fashion-sector work.
"Clean", "planet-friendly"
Beauty and personal-care lines built on green positioning and in-house eco badges.
"Green", "biodegradable"
Direct-to-consumer, cleaning and homecare brands with claims that now need accessible substantiation.
If you also sell to EU consumers, that's a separate regime with a different test and a September 2026 switch-on date — see our EU edition. This tool is about UK law.
