How to Spot Greenwashing in Fashion: 10 Red Flags

Last Updated: October 2025

In 2025, an Italian court fined Shein €1 million for greenwashing, finding its sustainability messaging vague, generic, and misleading. H&M had 96% of their sustainability claims debunked in a 2021 report. These aren’t isolated incidents – greenwashing is rampant in fashion.

As consumers demand more sustainable options, brands have responded. Unfortunately, many are faking it. They slap “eco” and “conscious” labels on products whilst continuing business as usual behind the scenes.

This guide will teach you exactly how to spot greenwashing so you can support genuinely sustainable brands and avoid being duped by clever marketing.

What Is Greenwashing?

Greenwashing is when companies falsely portray themselves as environmentally friendly to capitalise on growing consumer demand for sustainable products.

Common tactics:

• Vague, unmeasurable claims (“eco-friendly,” “conscious”)
• Highlighting one small green initiative whilst ignoring massive environmental damage elsewhere
• Creating “sustainable collections” that represent 5% of production
• Using nature imagery and green packaging to imply sustainability
• Making ambitious promises without accountability

Why it matters:

• You waste money on products that aren’t actually sustainable
• Genuinely ethical brands lose business to fakers
• Environmental damage continues unchecked
• Workers continue to be exploited
• Reduces pressure on industry to actually change

The fashion industry produces 10% of global carbon emissions. We need real change, not marketing spin.

10 Red Flags of Greenwashing

1. Vague, Meaningless Terms

Red flag: Words like “eco-friendly,” “conscious,” “responsible,” “green,” or “sustainable” without specifics.

Why it’s greenwashing: These terms have no legal definition. Anyone can use them without proving anything.

Real examples:

• H&M’s “Conscious Collection”
• Zara’s “Join Life”
• Boohoo’s “Ready for the Future”
• Primark’s vague sustainability claims

What to look for instead:

• Specific, measurable claims: “Made from 100% GOTS-certified organic cotton”
• Certifications from independent bodies
• Quantifiable data: “Uses 70% less water than conventional cotton”
• Clear explanations of how they achieve sustainability

Example of good communication: “This t-shirt is made from 100% organic cotton (GOTS certified), manufactured in a Fair Trade certified factory in Portugal, using water-based dyes.”

vs

“This t-shirt is part of our eco-conscious collection.”

2. Tiny “Sustainable” Collection

Red flag: Brand highlights a small “sustainable” or “eco” range whilst the vast majority of their products remain unchanged.

Why it’s greenwashing: One eco collection among 100 conventional collections doesn’t make a brand sustainable. It’s a marketing ploy to capture eco-conscious consumers without changing their harmful business model.

Real examples:

• H&M’s Conscious Collection represents a tiny fraction of their 3 billion annual garments
• Zara’s Join Life collection is a small percentage of their 450 million annual garments
• Most high street brands with “sustainable ranges”

What to look for instead:

• Brands where sustainability applies to entire range
• Clear timeline for transitioning all production to sustainable methods
• Majority of products meeting high environmental/ethical standards

Questions to ask:

• What percentage of your total production is this sustainable range?
• What about your other collections?
• When will all your products meet these standards?

3. Focus on Packaging, Not Product

Red flag: Brands loudly tout recycled packaging, paper bags, or minimal packaging whilst ignoring the actual environmental impact of producing the clothes themselves.

Why it’s greenwashing: Packaging represents a tiny fraction of fashion’s environmental footprint. The real damage comes from material production, manufacturing, and disposal. Focusing on packaging distracts from bigger issues.

Real examples:

• Brands promoting paper bags whilst using virgin polyester
• “Recycled packaging” on fast fashion items
• Instagram-worthy minimal packaging on unsustainable products

What to look for instead:

• Brands addressing materials, production, and worker welfare
• Transparent about entire supply chain
• Sustainable packaging as a bonus, not the main claim

Reality check: Eco-friendly packaging on a £3 polyester dress that falls apart after three wears isn’t sustainable.

4. Office Green Initiatives Only

Red flag: Promoting solar panels on headquarters, office plants, LED lighting, or other head office eco-initiatives whilst supply chain remains polluting.

Why it’s greenwashing: The head office’s environmental impact is negligible compared to manufacturing facilities. This is performative sustainability.

What to look for instead:

• Supply chain transparency
• Factory energy sources
• Manufacturing environmental impact data
• Worker conditions throughout supply chain

The real question: What happens in the factories where clothes are actually made?

5. No Third-Party Certifications

Red flag: Sustainability claims without independent verification from recognised certification bodies.

Why it’s greenwashing: Anyone can claim anything. Third-party certifications require meeting specific, audited standards.

Legitimate certifications:

• GOTS (Global Organic Textile Standard)
• Fair Trade Certified
• B Corp
• OEKO-TEX
• Leather Working Group
• Bluesign
• Cradle to Cradle

Fake or weak certifications:

• Brand’s own “eco” labels
• Vague “certified sustainable” without naming certifier
• “Approved by” unnamed bodies

What to look for:

• Logos of recognised certifications
• Certification details available online
• Multiple certifications (shows commitment)

6. Hidden Trade-Offs

Red flag: Highlighting one eco-friendly aspect (like recycled polyester) whilst ignoring other harmful practices (fossil-fuel powered factories, exploitative labour, overproduction).

Why it’s greenwashing: A product made from recycled materials can still be produced unethically, in polluting factories, designed to fall apart quickly, and contributing to overconsumption.

Real examples:

• “30% recycled polyester!” (but 70% is virgin plastic, and it’s made in sweatshops)
• “Organic cotton!” (but dyed with toxic chemicals and sewn by exploited workers)
• “Water-saving techniques!” (but massive overproduction creates waste)

What to look for:

• Holistic sustainability (materials AND production AND labour AND longevity)
• Brands addressing multiple issues, not just one
• Transparency about challenges and trade-offs

Questions to ask:

• Where and how is this made?
• What are working conditions like?
• Is it designed to last?
• What happens to it at end of life?

7. Ambitious Targets, No Accountability

Red flag: Vague future promises (“carbon neutral by 2050,” “100% sustainable by 2030”) without concrete plans, interim targets, or current progress reports.

Why it’s greenwashing: Shein’s emissions reduction targets were flagged as generic and contradicted by actual emission increases in 2023 and 2024. Future promises mean nothing without action today.

What to look for:

• Detailed action plans
• Annual progress reports
• Interim targets (not just distant goals)
• Third-party verification of progress
• Honest reporting about challenges

Good example: “We’re currently 40% through our target to use 100% renewable energy by 2027. Last year we achieved 35%, up from 28% the previous year. Here’s our annual progress report…”

Bad example: “We aim to be carbon neutral by 2050.”

8. Percentage Tricks

Red flag: Highlighting a small percentage of sustainable materials or practices as if it represents the whole.

Why it’s greenwashing: “Made with 30% recycled polyester” means 70% is virgin plastic. “Some sustainable materials” could mean 5%.

Real examples:

• “Contains recycled materials” (could be 10%)
• “Partially organic cotton” (could be 20% organic, 80% conventional)
• “Some eco-friendly practices” (vague and unquantified)

What to look for:

• Specific percentages clearly stated
• Higher percentages (50%+ minimum, 100% best)
• Breakdown of all materials used

The rule: If they don’t tell you the percentage, it’s probably very low.

9. Natural Doesn’t Mean Sustainable

Red flag: Terms like “natural,” “plant-based,” or “biodegradable” without context.

Why it’s greenwashing: Conventional cotton is natural but uses massive amounts of water and pesticides. Viscose is plant-based but often involves deforestation. “Natural” doesn’t automatically equal “sustainable.”

What to look for:

• Specific sustainable natural materials (organic cotton, linen, hemp)
• Certifications proving sustainable sourcing
• Details about production methods

Reality check: Conventional cotton is one of the most environmentally damaging fabrics despite being natural.

10. No Supply Chain Transparency

Red flag: Refusal to publish supplier lists, factory information, or supply chain details.

Why it’s greenwashing: If a brand truly operates ethically and sustainably, they’ll be transparent about it. Secrecy suggests something to hide.

What to look for:

• Published supplier lists
• Factory locations and conditions
• Worker wage information
• Supply chain maps
• Willingness to answer questions

Tools to check:

• Fashion Transparency Index (annual brand rankings)
• Good On You app
• Brand websites (check “About” and “Sustainability” pages)

Real-World Greenwashing Examples

H&M: The Serial Offender

The claims: “Conscious Collection,” “sustainable fashion,” “we take sustainability seriously”

The reality: 96% of H&M’s sustainability claims were found to be misleading in a 2021 report. Their “Close the Loop” recycling program sent clothes with tracking devices halfway around the world instead of to recycling facilities. The Conscious Collection represents a tiny fraction of their 3 billion annual garments.

The verdict: Greenwashing

Shein: Fined for Deception

The claims: #SHEINTHEKNOW campaign, evoluSHEIN collection, social responsibility messaging

The reality: Fined €1 million for greenwashing in 2025. Claims were vague, generic, misleading, with false information about recyclability and circular systems. Emissions actually increased despite reduction targets.

The verdict: Egregious greenwashing [link to your Shein post]

Zara: Small Green Collection, Massive Production

The claims: “Join Life” collection with “environmentally conscious production”

The reality: Join Life represents a fraction of Zara’s 450 million annual garments. The majority are still produced using fast fashion methods with rapid cycles and substantial waste.

The verdict: Greenwashing through selective highlighting

Boohoo: Ready for What?

The claims: “Ready for the Future” range using recycled materials, calling it easier to “dress more sustainably”

The reality: Ultra-fast fashion brand with poor labour practices. One recycled range doesn’t address business model based on disposability and overproduction.

The verdict: Greenwashing

FAQs

1. Is all sustainable fashion marketing greenwashing?

No! Genuine sustainable brands exist and deserve support. The difference is specificity, transparency, and third-party verification. Real sustainable brands provide detailed information, hold certifications, and address their entire operation – not just one product line. Use tools like Good On You to distinguish genuine brands from greenwashers.

2. Why do big brands greenwash instead of actually being sustainable?

Because true sustainability costs money and requires fundamental business model changes. Greenwashing is cheaper – they can appear sustainable through marketing without incurring costs of fair wages, organic materials, or transparent supply chains. Plus, the fashion industry is under-regulated, so brands face minimal consequences for false claims. Consumer demand for sustainability exists, but many brands want the sales without the investment.

3. Can a fast fashion brand ever be truly sustainable?

No. Fast fashion’s business model – producing massive quantities cheaply, encouraging constant purchasing, designing for disposability – is fundamentally incompatible with sustainability. A fast fashion brand with a “sustainable collection” is still contributing to overconsumption and waste. Genuine sustainability requires slower production, quality over quantity, fair wages, and designing for longevity.

4. What should I do if I’ve already bought from greenwashing brands?

Don’t throw items away – that creates more waste! Wear what you have until it’s truly worn out. Moving forward, stop buying from greenwashing brands and research before purchases. Share what you’ve learned with others. The past is past; focus on making better choices now.

5. Are high street brands with “eco ranges” worth buying from?

Generally no. When H&M, Zara, or Primark create small sustainable ranges, it’s typically greenwashing. These ranges represent tiny fractions of their production whilst the vast majority remains unchanged. Your money still supports a fundamentally unsustainable business model. Better options exist at similar price points [link to your affordable brands post].

6. How do I know if certifications are legitimate?

Research the certification body. Legitimate certifications (GOTS, Fair Trade, B Corp) have public databases where you can verify a brand’s certification. Check the certification website to confirm the brand is listed. Be wary of brands creating their own “eco” labels without independent verification.

7. Is “recycled polyester” sustainable or greenwashing?

It’s complicated. Recycled polyester (from plastic bottles) is better than virgin polyester, but it’s not perfect. It still releases microplastics when washed and isn’t biodegradable. Brands highlighting recycled polyester whilst ignoring labour issues or overproduction are greenwashing. Brands using it as part of holistic sustainability (plus fair labour, quality construction, take-back programs) are making genuine efforts.

8. Why don’t governments regulate greenwashing in fashion?

Some progress is happening. The EU is developing regulations, and Italy fined Shein €1 million for greenwashing in 2025. However, regulation is slow and industry lobbying is strong. Until comprehensive laws exist, consumer awareness and purchasing choices are our most powerful tools.

9. Can I trust brands that are “working towards” sustainability?

Maybe. Look for specifics: What exactly are they doing? What’s the timeline? Do they publish progress reports? Are there interim targets? Honest brands will be transparent about where they are now, concrete steps they’re taking, and challenges they face. Vague “we’re working on it” without details is a red flag.

10. What’s the difference between greenwashing and genuine imperfection?

Genuine sustainable brands are transparent about challenges and imperfections. They’ll say “We’re not perfect, here’s what we’re still working on.” Greenwashers claim perfection with vague terms whilst hiding problems. Transparency and honesty about the journey indicate genuineness. Secrecy and exaggerated claims indicate greenwashing.
