You’ve seen the leafy labels and wondered if they mean anything. So, what is greenwashing in fashion? It’s marketing that makes a product look more eco-friendly than the evidence supports.

Figures come from the European Commission’s green claims page and the UK CMA case page. They can change, so check the sources before you rely on them.
This guide is part of our wider look at sustainable fashion. It is independent and educational, and it is not connected to any brand or organisation named here.
What greenwashing looks like on a clothing label
Greenwashing is a gap between what a brand says and what it can show. The clothes may not be bad. The problem is a claim that is bigger, vaguer or less proven than it sounds.
In fashion it tends to show up in a few familiar ways:
- Vague words such as “conscious”, “eco”, “green” or “planet-friendly”, with no explanation of what is different.
- Nature imagery: leaves, earth tones and green hang tags that suggest benefit without stating one.
- Cherry-picked facts: one recycled fibre highlighted while the rest of the garment is ordinary.
- Future promises with no plan, such as “working towards a better future”.
- Made-up badges: a self-designed seal that looks like independent certification.
None of these is proof of bad intent. Each one is a prompt to ask what is behind the claim.
How common are misleading green claims?
The European Commission’s green claims page states that 53% of green claims give vague, misleading or unfounded information. That figure covers products in general, not only clothing, but it shows how often shoppers meet claims that don’t hold up.
Fashion is a natural target for scrutiny. Garments are sold on emotion and image, and the supply chain behind a single shirt is long, which makes simple claims hard to check.
What regulators have done about fashion claims
Regulators now treat fashion claims as a priority. The UK Competition and Markets Authority (CMA) opened its fashion case on 29 July 2022, according to its case page.
The CMA recorded commitments from ASOS, Boohoo and George at Asda on 27 March 2024 concerning the clarity and accuracy of their environmental marketing. The page says they must ensure all green claims are accurate and not misleading. Undertakings are promises made to a regulator, and they are not a finding that the law was broken.
One detail is useful for shoppers. Search filters must be accurate, so a “recycled” filter should only show items made from predominantly recycled materials.
The CMA also sent an open letter urging fashion retailers to review their own claims, and it issued a tailored guide for fashion brands on 18 September 2024. That tells you what the regulator expects: specific, evidenced and clearly explained claims.
Common phrases and what to ask about them
Some phrases appear again and again in fashion marketing. Each can be honest, but each needs a follow-up question before you trust it.
- “Sustainable collection”: What makes it sustainable, and how does the rest of the brand’s range compare?
- “Made with recycled materials”: Which materials, and how much of the garment do they make up?
- “Natural” or “plant-based”: Natural fibres can still carry heavy environmental costs, so ask how they were grown, processed and dyed.
- “Biodegradable” or “compostable”: Does it break down in real conditions, or only in a specialist facility? Does the claim also cover zips, threads and dyes?
- “Carbon neutral”: Is it reductions in the supply chain, or mostly offsets bought elsewhere?
A good answer is short, specific and easy to find. If you have to hunt for it, or it never arrives, that tells you something too.
Notice also who is speaking. A brand’s own website is a marketing channel, so independent certification, third-party reporting and journalism carry more weight than a self-written sustainability page.
A quick checklist for spotting greenwashing
You don’t need to be an expert. Run a product page through these steps:
- Look for specifics. Does it name the material, the share used and what it replaces?
- Check the scope. Does the claim cover the whole garment, or only a trim, a tag or one line within a range?
- Find the evidence. Is there a named certification, a report or a link you can read?
- Read the comparison. “Better” than what? A claim without a baseline says very little.
- Check the rest of the brand. A small “conscious” range beside constant new drops tells its own story.
If a page fails most of these checks, treat the claim as marketing rather than information.
Buying better when claims are hard to trust
The most reliable step is often to buy less and keep items longer. Labels can mislead, but a garment you wear for years has a clear advantage over one worn twice.
Buying used is another option, but environmental claims about secondhand clothing still deserve scrutiny. Our guide on how to shop secondhand clothes covers how to do it well.
It also helps to understand the wider mindset of buying fewer, better pieces. If that appeals, read about what is slow fashion for a fuller picture.
Why brands do it, and why it matters to you
Shoppers increasingly say they want greener clothes, and brands know it. A green label can justify a higher price or ease a buyer’s guilt, which gives companies a reason to stretch the truth.
The cost falls on you and on the people trying to make real progress. You may pay extra for little benefit, and honest brands that do the harder work get lost among louder, vaguer competitors.
There is a quieter harm too. When shoppers learn that many claims are empty, they can become cynical and stop caring at all. Learning to question claims calmly, rather than dismissing everything, keeps your attention on what actually matters.
A few habits help:
- Pause before buying something because of its eco label alone.
- Prefer brands that publish plain details about materials, factories and limits.
- Value honesty about what is not yet solved over polished perfection.
- Judge the whole business model, not a single capsule range.
Honest brands tend to say what they have not fixed yet. That candour is usually a better sign than a spotless story.
Frequently asked questions
Is greenwashing illegal?
Show answer
It can be. Misleading environmental claims may breach consumer protection rules, which is why regulators such as the UK CMA investigate them. Whether a particular claim breaks the law depends on the facts and the local rules.
Does a green claim mean a brand is lying?
Show answer
No. A claim can be vague, incomplete or poorly evidenced without being a deliberate lie. The useful question is whether it is specific and backed by evidence.
Are recycled materials always a good sign?
Show answer
Not automatically. Check how much of the garment is made from them and whether the claim covers the whole product. In the CMA’s search-filter example, a filter for recycled trousers should show only trousers made predominantly from recycled materials.
Do certifications prove a product is sustainable?
Show answer
They help when they are independent, named and verifiable. A badge a brand invented itself is not the same thing, so look for who runs the scheme and what it covers.
