Vegan Shoes & Sustainability: What Labels Don’t Tell You
Nae Vegan ShoesLook at the sustainability page of almost any shoe brand and you will find a row of logos. Most of us read them as a general endorsement: this company is one of the good ones. That is not what they mean. Each certifies something quite narrow, and the interesting part — the part nobody advertises — is what falls between them.
This is a guide to reading them properly: what each one actually proves, what none of them proves, and why the absence of a logo is sometimes the most informative thing on the page.
What each label actually certifies
The first thing to understand is that these are not competing grades of the same thing. They measure different things entirely, and a brand holding one is not ‘more certified’ than a brand holding another.
| Label | What it actually verifies |
|---|---|
| OEKO-TEX Standard 100 | The finished product, tested against a list of over a hundred harmful substances. Every component — lining, thread, zips, labels — must pass. |
| OEKO-TEX STeP | The facility: chemical management, environment, health and safety, social conditions. |
| OEKO-TEX Made in Green | Combines the two above and adds a traceable product ID. |
| GOTS | Organic fibre content plus environmental and social criteria at every processing step. 95% organic fibre to say ‘organic’; 70% for ‘made with organic’. |
| GRS | Recycled content with chain-of-custody documents, plus social and chemical criteria. 50% content for a full claim. |
| RCS / OCS | The lighter versions: they verify content only, with no process, chemical or social criteria. |
| bluesign | Chemical inputs, controlled upstream — preventing hazardous substances entering rather than testing for them at the end. |
| ZDHC MRSL | A restricted-substances list applied at the manufacturing source rather than to the finished item. |
| FSC | That forest-derived material — cork, paper, packaging — comes from responsibly managed forests, with chain of custody. |
| USDA BioPreferred | The percentage of bio-based carbon in a material, measured by laboratory test. |
| ISO 9001 / ISO 14001 | That the company operates a quality or environmental management system. |
Five things a label does not tell you
Now the gaps — and these matter more than the list above.
- It only covers what it says it covers. A certificate applies to specific processes at a specific site. A factory certified for knitting cannot make the same claim about cutting and sewing.
- ISO 14001 certifies a system, not a result. This is the most widely misread badge in the industry. It confirms that a company has an environmental management framework in place; it does not set environmental performance requirements.
- OEKO-TEX Standard 100 says nothing about how the product was made. It is a skin-safety test on the finished item. The garment could have been produced in a facility with poor environmental controls or bad working conditions and still pass, because those are simply not what it examines.
- Recycled thresholds are lower than most people assume. ‘Made with recycled materials’ can rest on an RCS certificate covering as little as a fifth of the content. GRS is the more demanding standard, and it is worth asking which of the two is behind a claim.
- Almost none of them measure how long the thing lasts. This is the great absence — which is why a garment can be organic, recycled, chemically tested and still fall apart in a season.
Where a certificate applies. Reading the scope matters more than reading the logo.

Simplified: ✓ covered, ~ partly, — not covered. The last column is the point — nothing here measures how long a product lasts. The EU’s new ecodesign rules will be the first to.
The part almost nothing covers: what the material is made of
Two families of substance dominate the concern here. PFAS — the ‘forever chemicals’ used to make things water- and stain-resistant — are extremely persistent, and the body cannot break them down. Phthalates, used to soften plastics, are found across petrochemical-based synthetics.
Here is the uncomfortable part for our own industry, and we would rather say it than have you discover it: phthalates are common in petrochemical synthetics, and that includes a good deal of what is sold as vegan leather. Being animal-free and being chemically clean are separate questions, and only one of them is answered by the word vegan.
Regulation is closing on this fast. France has banned PFAS in clothing, footwear and waterproofing agents from January 2026, extending to all textiles by 2030. Denmark restricts fluorine in clothing and footwear from July 2026. Under REACH, PFHxA is restricted in apparel textiles from October 2026. And the EU’s ecodesign framework already covers thousands of substances, with new hazard classes — including endocrine disruption — taking effect this year.
If you want a single practical rule: GOTS prohibits PFAS outright, and treatments sold as waterproof or stain-resistant are the place to ask questions first.
And if you want a shortcut: our own shoes are made without either family of substance, and we can show you the certificates behind that.
Why some brands show nothing at all
Certification costs money, but more importantly it requires knowing your own supply chain. Every one of these standards depends on documentation moving with the goods — transaction certificates, scope statements, audited sites. A brand that cannot name the facilities making its products cannot certify them, however much it might like to.
So when a company talks warmly about sustainability but lists no standards, no scopes and no certifying bodies, the most likely explanation is not modesty. And there is a related tell: legitimate certification is always third-party, issued by an accredited body such as Control Union, Hohenstein or Ecocert. A ‘certificate’ from a supplier’s own internal audit, or from a body nobody can find, is a logo rather than a verification.
And the worst proxy of all: the country on the label
Most people carry an internal map of which countries make things well and which do not. It is worth saying plainly that this map is now badly out of date, and that it does more harm than good.
Take the case that surprises people most. China’s textile industry has undergone an enormous, state-driven shift: a national green-factory certification programme running since 2016, an industrial standards plan for 2026 to 2028 calling for more than three hundred new standards covering green manufacturing and health and safety, and a zero-carbon factory scheme that begins selecting benchmark plants this year and reaches textiles by 2030. Its investment in solar, wind and hydro lets factories draw on genuinely clean electricity, and its supply is reliable in a way that several other garment-producing countries cannot match. Industry analysis describes it as well positioned to become a centre for low-carbon, circular and technologically advanced production, and its best facilities hold the same OEKO-TEX, GRS, GOTS and ISO certificates as anywhere else.
The honest picture includes the other side. The national grid remains carbon-intensive even as renewables expand; and on sustainable manufacturing specifically, at least one comparative assessment places some neighbours ahead. None of that is erased by a certificate. There is a long way to go, but the pace and the direction look encouraging.
But that cuts both ways, which is the actual point. A European address guarantees nothing either — Europe has had its own textile scandals, and ‘made in’ often refers only to the final assembly step, not the dyeing, tanning or finishing where most of the impact sits. There is a lot to do here too, but some things point in a good direction.
Judge the facility, not the flag. A postcode is not a standard.
Where we stand
For our own part: our materials carry certification from their suppliers — OEKO-TEX on the certified microfibre we line and build with, GRS on recycled content in several styles, and USDA-verified bio-based content and PETA approval on the plant leathers. The cactus leather we introduced this season carries USDA Biobased, OEKO-TEX, GRS and PETA certification from its maker. To have a more exhaustive picture you can see the range on our materials page.
And the limits, since that is what this article is about. We do not hold facility-level certification for every process in our chain, and we publish what our oversight does not cover in our work ethics reporting rather than leaving it implied — we wrote about that here. A certificate on a material is not the same as a certificate on a factory, and we would rather you knew the difference than assumed the stronger version.
How to read a claim, in four questions
- Which standard, and issued by whom? A named standard and an accredited certifying body, or it is decoration.
- What is the scope? Which processes, at which site, and does that cover the product you are actually buying?
- What does this standard deliberately not measure? Chemistry, materials, labour and durability are four different questions, and most labels answer one.
- What is missing entirely? If nothing addresses how long the product lasts, that silence is the answer to the most important question of all.
None of this means certification is theatre. It means a label is a specific, verified, narrow statement — and treating it as a general blessing is how good schemes end up doing greenwashing’s work for it. If you want the wider argument, our piece on whether vegan shoes are actually sustainable takes it further, and our values page sets out what we are trying to do.
A certificate answers the question it was asked. The skill is knowing which question that was.
