Sustainability Claims: What a UK Clothing Brand Can Actually Say
By The Velocity Wear Team
Nearly every new clothing brand wants to say something about sustainability, and nearly every one reaches for the same vocabulary: eco-friendly, sustainable, conscious, planet-friendly. The CMA's Green Claims Code exists largely because that vocabulary means nothing checkable, and unsubstantiated environmental claims are a consumer protection issue rather than a stylistic one.
The useful reframing: a claim you cannot evidence is not a claim, it is decoration. And specific, evidenced claims are considerably better marketing anyway.
What the Code asks of a claim
Broadly, that claims are truthful and accurate, clear and unambiguous, that they do not omit or hide important information, that comparisons are fair and meaningful, that they consider the full life cycle of the product, and that they are substantiated. That last one is the load-bearing requirement — you need evidence, held, before you publish.
The "full life cycle" element is the one that catches apparel out. A garment made from recycled fibre, shipped by air, sold with free returns and worn twice is not straightforwardly better than the alternative, and a claim implying it is may not survive scrutiny.
Words that create problems
- "Eco-friendly" and "environmentally friendly", which imply an overall benefit that essentially no physical product can substantiate.
- "Sustainable" used unqualified, as an adjective describing a garment rather than a specific practice.
- "Natural", which says nothing about environmental impact and is frequently used as though it does.
- "Carbon neutral" without stating exactly how, including the role of offsetting, which the Code treats with particular care.
- "Recyclable" where no practical route exists for a consumer to recycle a mixed-fibre garment.
What holds up instead
Specific factual statements about specific attributes, each of which you can evidence. "Made from certified organic cotton" with the certification named. "Shipped by sea." "Printed with water-based inks." "Packaged in paper mailers rather than plastic."
Each of those is narrow, checkable, and does not imply anything beyond itself. Collectively they tell a customer far more than an "eco-friendly" badge, and they cost you nothing but accuracy.
Certification claims need the certificate
Organic and recycled content claims generally rest on certification schemes with chain-of-custody requirements. Saying a garment is organic cotton means the fibre is certified and the chain is documented — a supplier saying the fabric is organic in an email is not the same thing.
If you intend to make a certified-fibre claim, ask for the certification documentation at quoting stage and keep it. Ask specifically whether the certification covers the garment as produced or only the fibre input, because the distinction matters and is frequently glossed over.
The claim that is always available
Durability. A garment that lasts is straightforwardly better than one that does not, and unlike most environmental claims it is a property your customer can verify by owning it.
It is also something you can actually influence: a heavier fabric, better rib recovery, twin-needle seams, a decoration method that survives washing, and honest care instructions all extend the life of a garment. That is a real environmental contribution and a real product improvement at the same time, and it needs no substantiation file because it is not an environmental claim at all.
The house rule
If you cannot point at the evidence in under a minute, do not publish the claim. That single test removes almost all greenwashing risk and, in our experience of writing product copy, improves the copy.
