You're standing in a surf shop, holding two kids' wetsuits. One says "eco-friendly" on the tag. The other says "sustainable materials." Both cost roughly the same. Both look basically identical.
Which one is actually better for the planet?
The honest answer: you can't tell from the label. And that's exactly the problem.
Greenwashing — making products sound more environmentally friendly than they actually are — has become so widespread in swimwear and fashion that even well-intentioned parents are being misled by marketing designed to look like transparency.
Here's how to see through it.
The Scale of the Problem
In 2022, the ACCC found that 57 percent of businesses reviewed made concerning environmental claims. The fashion and textile industry was among the worst offenders. Terms like 'eco-friendly,' 'sustainable,' and 'ocean-positive' have no legal definition in Australia, allowing brands to use them without evidence or accountability.
In 2022, the ACCC (Australian Competition and Consumer Commission) reviewed 247 businesses across eight sectors for environmental claims. The findings were damning:
- 57% made concerning environmental claims
- The textiles, garments, and shoes sector ranked second worst at 67% — two out of every three brands making claims the ACCC found problematic
- The most common issues: vague terms like "green" and "eco-friendly" with no evidence, products marketed as recyclable without proof, and brands creating their own "certifications" without independent oversight
Roughly 60% of sustainability claims across fashion are unsubstantiated or misleading. And only 20% of consumers actually believe brand sustainability claims, according to a 2025 Blue Yonder survey. Which means most of us already suspect we're being lied to — we just don't know exactly how.
The Seven Greenwashing Tricks to Watch For
The most common greenwashing tactics in swimwear include vague language without evidence, highlighting one sustainable feature while ignoring harmful practices, self-created certification logos, misleading imagery of nature, hidden trade-offs, irrelevant claims about things already required by law, and the lesser-of-two-evils comparison that avoids the real issue.
1. Vague, Meaningless Language
Words like "eco-friendly," "green," "conscious," "responsible," and "sustainable" have no legal definition and no required standard. Any brand can print them on a label. Literally any brand. There is no test, no audit, no verification.
If a product says "eco-friendly" but doesn't tell you why — what specifically is eco-friendly about it, verified by whom — it's marketing, not information.
2. The "Conscious Collection" Trick
This is a favourite of fast fashion: create a small "sustainable" line within a massive operation.
Zara's "Join Life" collection represents roughly 15% of total production. The remaining 85% uses traditional fast fashion processes. Shein launched an "Our Products/Our Planet" campaign claiming to produce only 50–100 items per product initially, but stopped short of detailing thresholds or committing to sustainable materials.The trick works because you see the green label in the store and associate the entire brand with sustainability. If a brand has 500 products and only 30 are in the "eco" range, the brand isn't sustainable — it has a sustainable marketing campaign.
3. "Recycled Polyester" (The Microplastics Problem)
This one sounds good. It isn't.
98% of recycled polyester comes from plastic bottles — not textile waste. This is bottle-to-textile downcycling: it removes bottles from closed-loop bottle-to-bottle recycling systems, turns them into garments that shed microplastics, and cannot be effectively recycled again.A December 2025 report by the Changing Markets Foundation found that recycled polyester sheds 55% more microplastic fibres than virgin polyester — an average of 12,430 fibres per gram compared to 8,028. The particles are also nearly 20% smaller, making them more harmful and able to spread further in the environment.
Europe's beverage industry has been urging policymakers since 2021 to stop fashion brands from downcycling their bottles into textiles.
4. "Limestone Neoprene" (The Surf Industry's Favourite)
This is the biggest greenwashing claim in the wetsuit industry. Many brands market limestone neoprene as an eco-friendly alternative to petroleum neoprene.
Patagonia's own analysis concluded: "Both petroleum- and limestone-based polychloroprene have equally significant environmental impacts."Why? Because they're chemically identical — polymerised chloroprene, regardless of source. The limestone process still involves mining with heavy machinery, heating to 2,000°C, and seven chemical transformations producing toxic waste including acetylene gas.
Limestone neoprene is not green neoprene. It's the same product with different marketing.
5. "Recycled Neoprene" Claims
Neoprene cannot currently be recycled back into raw neoprene for new wetsuits. The combination of different materials (rubber, nylon linings, polyester, glue, metal zips) makes it nearly impossible with current technology.What actually happens: old neoprene is shredded and turned into products like yoga mats, playground matting, and boxing bag fillings. That's better than landfill, but it's not recycling in the way most people understand the word.
6. Carbon Offset Claims
Some brands claim "carbon neutrality" through offsets — paying someone else to plant trees or capture emissions rather than reducing their own. Scope 3 (supply chain) emissions account for over 90% of a fashion brand's footprint, and offsets allow brands to avoid touching these.
Research consistently shows companies buy the cheapest, lowest-quality offsets available. When the goal is a good story rather than real impact, the cheaper the better.
7. Green Imagery Without Substance
The UK's Competition and Markets Authority found that ASOS, Boohoo, and George at Asda were using green leaves, natural imagery, and sustainability logos to suggest products were more environmentally friendly than they actually were. All three were required in March 2024 to sign formal undertakings to stop.
If a product's environmental story is told through leaf icons and earth-tone packaging rather than specific, verifiable claims — be sceptical.
What Australia Is Doing About It
The ACCC has made greenwashing an enforcement priority, issuing fines and infringement notices to businesses making misleading environmental claims. Australian Consumer Law prohibits false or misleading representations about products. In 2024, the ACCC published specific guidance for businesses on how to make truthful sustainability claims.
The ACCC isn't messing around.
In December 2023, the ACCC published eight principles for environmental claims. The core requirements: claims must be accurate, evidence-backed, specific, not misleading through omission, and clear to an average consumer.
The penalties for getting it wrong are serious:
| Case | Penalty | What Happened |
|---|---|---|
| Vanguard Investments | $12.9 million (Sept 2024) | Misrepresented ESG screening — 74% of securities were never screened |
| Mercer Super | $11.3 million (Aug 2024) | Greenwashing of super fund ESG claims |
| Clorox (GLAD bags) | $8.25 million (April 2025) | Marketed bags as "50% Ocean Plastic" — plastic was collected up to 50km from coastlines, not from the ocean |
Maximum penalties under Australian Consumer Law: the greater of $50 million, three times the financial benefit gained, or 30% of company turnover.
In February 2025, the ACCC confirmed greenwashing remains a priority for 2025–26, with several ongoing investigations in fashion and textiles.
The Certifications That Actually Mean Something
Meaningful third-party certifications include OEKO-TEX Standard 100 (tested free from harmful substances), FSC (sustainably sourced materials), Global Recycled Standard (verified recycled content), and bluesign (responsible textile production). Self-created logos and unverified claims like 'eco-friendly' or 'ocean-safe' are not certifications.
Not all labels are created equal. Here's what's real and what's marketing.
Certifications Worth Trusting
FSC (Forest Stewardship Council)- Certifies responsibly managed forests and sustainable sourcing
- Independent audits by the Rainforest Alliance
- Publicly searchable database — you can verify any claim at info.fsc.org
- Relevant to: natural rubber sourced from rubber tree plantations (like Yulex)
- The world's largest forest certification system, covering two-thirds of globally certified forest area
- Actually requires a higher percentage of certified material (70%) than FSC (50%)
- Relevant to: same as FSC — sustainable forestry and rubber sourcing
- Tests finished products for over 100 harmful substances including heavy metals, pesticides, carcinogenic dyes, phthalates, and formaldehyde
- Children's clothing has stricter limits than adult products
- Focuses on safety of the finished product against skin — particularly important for swimwear
- Certifies the entire business, not just a product
- Companies must achieve a minimum verified score across governance, workers, community, environment, and customers
- A company can't B Corp certify one product line while the rest operates unsustainably
Red Flags
- Brand's own "eco" label with no third-party auditing
- Self-assessed certifications that can't be independently verified
- Vague percentage claims ("made with recycled materials" — what percentage? Recycled from what?)
- No public database where you can look up the certification
The Parent's Greenwashing Checklist
Before buying any "sustainable" swimwear, ask these questions:
1. "What exactly is it made from?"Ask for specific material names — Yulex, ECONYL, organic cotton. If the answer is just "eco-friendly materials," that's a red flag.
2. "Which independent certifications does it have?"Look for FSC, PEFC, OEKO-TEX, or B Corp. If the brand has created its own green label, ask who audits it.
3. "Can I verify the certification?"Real certifications have public databases. FSC certificate holders can be verified online. OEKO-TEX labels can be checked at their website. If it can't be looked up, it doesn't count.
4. "Is this the standard for ALL products, or just a small eco line?"If a brand's "sustainable" range is 10% of their catalogue, the brand isn't sustainable. It has a marketing strategy.
5. "What about the rest of the supply chain?"A "recycled" label on the main fabric doesn't tell you about the thread, the zipper, the dyes, the packaging, or the working conditions.
6. "What happens at end of life?"Can it be recycled? Does the brand have a take-back program? A product that's "sustainable" to make but sits in landfill for 500 years has only solved half the problem.
7. "Are the numbers specific?""80% less CO₂ emissions" with a cited study is credible. "Better for the planet" with no numbers is advertising.
What Genuine Sustainability Looks Like
Genuine sustainability in swimwear means third-party certified materials with full supply chain transparency. It includes specific, measurable environmental claims backed by data — such as exact CO2 reduction percentages — rather than vague statements. Certifications like OEKO-TEX, FSC, and GRS are independently verified and publicly auditable.
We'll be transparent: this is where we talk about AVALY's approach. Feel free to skip ahead to the FAQ if you just wanted the checklist.
Every AVALY wetsuit uses:
- Yulex natural rubber — FSC and PEFC certified, independently audited by the Rainforest Alliance, with 80% lower CO₂ emissions than neoprene. Not a "conscious collection" — every wetsuit, every time
- ECONYL regenerated nylon — chemically identical to virgin nylon but made from rescued fishing nets and carpet waste, with up to 90% lower global warming impact. Infinitely recyclable — unlike "recycled polyester," which can't be recycled again
- No DWR coatings — no water-repellent chemical treatments (a common vector for PFAS)
- No limestone neoprene — because putting "limestone" in front of "neoprene" doesn't change the chemistry
- UPF 50+ protection — tested to AS/NZS 4399, the Australian/NZ standard. Not a self-assessed claim — independently tested
We didn't arrive at these materials by looking for the cheapest way to print "sustainable" on a label. We arrived at them by asking a simple question: if we wouldn't put it on our own kid's skin, why would we put it on yours?
The sustainable children's wear market is projected to reach $2.81 billion by 2032 — growing from $1.38 billion in 2024. That growth means more brands will enter the space. Some will be genuine. Many will be greenwashing.
The parents who can tell the difference are the ones who'll drive real change.
The Bottom Line
You don't need a degree in materials science to spot greenwashing. You just need to ask better questions.
If a brand can't tell you specifically what their products are made from, who certified them, and what happens at end of life — they're selling you a story, not a solution.
The ACCC has made it clear: vague environmental claims are on borrowed time in Australia. But regulation moves slowly. In the meantime, the most powerful tool you have is scepticism.
Read the label. Check the certification. Ask the questions. Your kid's swimwear should be as honest as it is warm.

Frequently Asked Questions
How do I know if a swimwear brand is actually sustainable?
Look for specific, independently verified certifications like FSC, PEFC, OEKO-TEX Standard 100, or B Corp. Ask the brand directly what their products are made from — genuine brands will name specific materials (Yulex, ECONYL, organic cotton) rather than vague terms like "eco-friendly." Check if their certifications can be verified in a public database.
Is limestone neoprene eco-friendly?
No. Patagonia's own analysis concluded that limestone neoprene and petroleum neoprene have "equally significant environmental impacts." They're chemically identical — both are polychloroprene. The limestone process still involves mining, heating to 2,000°C, and multiple toxic chemical transformations. It's the same product with different marketing.
What is greenwashing in the fashion industry?
Greenwashing is making a product or brand appear more environmentally friendly than it actually is. Common tactics include using vague language ("eco-friendly," "green"), creating small "conscious" collections within large fast fashion operations, and using green imagery or self-created certifications without independent verification. The ACCC found 67% of textile brands made concerning environmental claims.
Is recycled polyester actually sustainable?
It's more complicated than it sounds. 98% of recycled polyester comes from plastic bottles, not textile waste. This downcycling removes bottles from closed-loop recycling, creates garments that shed 55% more microplastics than virgin polyester, and the resulting fabric cannot be effectively recycled again. ECONYL recycled nylon is a genuinely different approach — it's depolymerised back to its molecular building blocks and can be recycled infinitely.
What penalties do Australian brands face for greenwashing?
Under Australian Consumer Law, maximum penalties are the greater of $50 million, three times the financial benefit gained, or 30% of company turnover. The ACCC has been actively enforcing these rules — Clorox received an $8.25 million penalty in April 2025 for misleading "Ocean Plastic" claims on GLAD bags.
What should I look for in kids' swimwear certifications?
The most relevant certifications for kids' swimwear are OEKO-TEX Standard 100 (tests for over 100 harmful substances with stricter limits for children's clothing), FSC/PEFC (verifies sustainable material sourcing), and UPF ratings tested to AS/NZS 4399 (the Australian standard for sun-protective clothing). Be wary of brand-created certifications that can't be independently verified.
