How do I know if a fashion brand is greenwashing?

Look for these red flags: vague terms like 'eco-friendly' or 'conscious' without specific data, tiny 'sustainable' collections while the main line is 90%+ polyester, recycled polyester claims (still sheds microplastics and contains the same chemicals), and no third-party certifications. The most reliable check is fabric composition — if a brand claims sustainability but most products are polyester blends, the marketing does not match the materials.

Is H&M Conscious collection actually sustainable?

Largely no. The Norwegian Consumer Authority found H&M's sustainability claims misleading, and their own data revealed that some Conscious items contained MORE synthetic material than regular-line equivalents. The Conscious label required only 50% 'more sustainable' materials, which could still mean 50% polyester blended with organic cotton. In 2022, H&M faced a class-action lawsuit over misleading sustainability scorecards.

Is recycled polyester actually better for the environment?

Marginally, but it is still problematic. Recycled polyester reduces virgin plastic production and uses less energy to produce, but it still sheds microplastics when washed (the same amount as virgin polyester), still contains the same chemical additives, is rarely recycled again at end of life (most textile-to-textile recycling is not yet viable at scale), and gives brands a 'sustainability' label for what is fundamentally the same synthetic fabric.

What is the difference between real sustainability and greenwashing in fashion?

Real sustainability is measurable and transparent: specific percentages, third-party certifications (GOTS, OEKO-TEX), public supply chain data, and actual material changes across the entire product range — not just a small capsule collection. Greenwashing uses emotional language, green imagery, vague promises, and selective data to create an impression of environmental responsibility without substantive change.

Which fashion sustainability certifications can I trust?

The most reliable certifications are GOTS (Global Organic Textile Standard) for organic fibres, OEKO-TEX Standard 100 for chemical safety testing, bluesign for manufacturing processes, and Cradle to Cradle for circular design. Be sceptical of brand-created labels and internal sustainability scores — these are not independently verified.

Greenwashing in Fashion: How to Spot Fake Sustainability Claims

Fashion brands have discovered that the word "sustainable" sells. The problem is that most of them are using it without doing much to earn it. A 2021 report by the Changing Markets Foundation found that 59% of sustainability claims by European fashion brands were misleading or unsubstantiated. The actual number is likely higher.

Here is how to see through the marketing — and what to look for instead.

What Is Greenwashing?

Greenwashing is the practice of making misleading claims about the environmental benefits of a product, service, or company practice. In fashion, it typically takes the form of vague language, selective data, tiny "conscious" collections, and recyclability claims that do not hold up to scrutiny.

The financial incentive is enormous. A 2023 McKinsey survey found that 67% of consumers consider sustainability when making a purchase. Brands that appear sustainable capture market share. Whether they actually are sustainable is a different question entirely.

The Most Common Greenwashing Tactics

1. Vague Language with No Data

Terms that sound meaningful but commit to nothing:

"Eco-friendly" — compared to what?
"Conscious" — of what, exactly?
"Sustainable materials" — which materials, and what percentage?
"Better for the planet" — better than what baseline?
"Responsibly made" — by whose definition of responsible?

None of these terms have legal definitions. Any brand can use them without consequence. If a claim does not include specific percentages, certifications, or verifiable data, it is marketing — not a sustainability commitment.

2. Tiny "Sustainable" Collections

The capsule collection trick: launch a small range of 30-50 "conscious" pieces, market it heavily, and let consumers assume the entire brand operates this way — while the other 95% of products remain unchanged.

H&M Conscious Some Conscious items had MORE synthetic than regular line

evoluSHEIN ~3% of Shein's catalogue; rest is 80%+ polyester

Mango Committed Small collection; main range still dominated by synthetic blends

3. The Recycled Polyester Claim

This is perhaps the most effective greenwashing tool in fashion today. "Made from recycled plastic bottles" sounds transformative. The reality is more complicated:

Recycled polyester sheds the same microplastics as virgin polyester — the fibres are chemically identical once processed
It contains the same chemical additives (antimony trioxide, disperse dyes, finishing agents)
Diverting PET bottles from bottle-to-bottle recycling (which is effective and scaled) into textile production (which is not) may actually reduce overall recycling efficiency
Less than 1% of clothing is recycled into new clothing — most textile-to-textile recycling remains technically and economically unviable at scale
The garment still ends up in landfill or incineration, where it takes 200+ years to decompose

Recycled polyester is marginally better than virgin polyester in production emissions. But calling it "sustainable" is a stretch when the end product is functionally the same synthetic fabric with the same end-of-life problems.

4. Misleading Certifications and Self-Scoring

Some brands create their own sustainability scoring systems — then grade themselves favourably. H&M's Higg Index-based sustainability profiles were so misleading that the brand faced a class-action lawsuit in 2022 and was forced to remove the scores from product pages.

Other tactics include:

Displaying legitimate certifications (like OEKO-TEX) on marketing pages while only a small fraction of products actually carry the certification
Using "certified sustainable" with internal, non-independent standards
Claiming membership in sustainability initiatives (like the Sustainable Apparel Coalition) as proof of sustainability — membership requires fees, not performance

5. The "Natural Material" Sleight of Hand

Advertising "made with cotton" or "contains organic cotton" while the actual composition is 30% cotton, 70% polyester. The natural fibre gets the headline; the synthetic majority gets the small print.

This is where fabric composition data becomes invaluable. When you can see the actual percentages, the gap between marketing and material reality becomes immediately obvious.

Real Examples: Marketing vs Material Reality

H&M Conscious / H&M Move

The Norwegian Consumer Authority concluded that H&M's Conscious collection claims were misleading to consumers. Our own fabric audit data shows that H&M's product range is heavily synthetic — the Conscious label required only 50% "more sustainable" materials, and "more sustainable" included things like recycled polyester. Some Conscious items were found to contain more synthetic material than their regular-line equivalents.

Shein evoluSHEIN

Shein launched evoluSHEIN as its sustainability line. The reality: it represents roughly 3% of Shein's total catalogue. Fibr's audit data shows that Shein's overall product range is approximately 80%+ polyester by product count. A tiny eco-labelled collection does not change the material reality of thousands of synthetic garments produced daily.

Zara Join Life / Mango Committed

Both Inditex and Mango launched "sustainable" sub-labels. Both represent a fraction of total output. And both use definitions of "sustainable material" that include recycled polyester and Tencel blends with majority synthetic content. The capsule collection exists for marketing; the supply chain continues as before.

How to See Through Greenwashing

Check the Fabric Composition

This is the single most reliable greenwashing detector. If a brand claims sustainability but the majority of its products are polyester-dominant, the claim does not hold. Fabric composition does not lie. It is printed on every label and listed (often reluctantly) on every product page.

Look for Third-Party Certifications

Certifications you can trust:

Certification	What It Covers	Independently Verified?
GOTS	Organic fibre + processing + labour	Yes
OEKO-TEX Standard 100	Chemical safety of finished product	Yes
bluesign	Manufacturing chemical safety	Yes
Cradle to Cradle	Material health + circularity	Yes
Brand self-scores	Varies	No

Check the Whole Range, Not the Capsule

A brand's sustainability is defined by what it sells the most of, not by its smallest collection. Look at the fabric composition across the brand's best-sellers and basics — that is where the material truth lives.

Demand Specifics

Legitimate sustainability claims include:

Exact percentages ("100% GOTS-certified organic cotton")
Named certifications on the actual product (not just the website)
Supply chain transparency (factory names, audit reports)
Targets with timelines, not aspirational language

Why Fabric Data Is the Best Greenwashing Detector

Marketing is subjective. Fabric composition is objective. When Fibr shows you that a "sustainable" garment is 65% polyester and 35% cotton, no amount of green branding can change that number. When you can compare a brand's "conscious" collection to its regular range and see the same synthetic-heavy compositions, the greenwashing becomes visible.

The data from our retailer fabric audits consistently shows the same pattern: brands talk about sustainability in marketing while selling predominantly synthetic products. The gap between claim and composition is measurable — and often enormous.
