Pick up a shirt in almost any Indian store this year and a tag will tell you it is sustainable. The word costs the brand nothing and proves nothing. Meanwhile the buyer, who is paying a little more for the promise, has no easy way to check it. That gap is the whole problem, and 2026 is the year the rules start to close it.
Sustainability stopped being a selling point and became the baseline
A few years ago, a sustainability claim set a brand apart. Now every label carries one, which means the claim on its own tells you nothing. The useful question moved from whether a brand says it is sustainable to whether it can show the work behind the word.
Why "eco friendly" and "sustainable" mean nothing on their own
Start with the two words themselves. Neither is regulated. A sustainable fashion journal points out that terms like eco friendly and sustainable lack verification, are not regulated, and are often used as a greenwashing tool. Anyone can print them on a tag. So treat them as the start of a question, not the answer, the same way you would read a fabric claim honestly.
The 2026 regulatory shift: claims must be defended
The ground is moving under those loose words. From late 2026, under the European Union's Empowering Consumers for the Green Transition Directive (the EmpCo Directive), generic environmental claims made without proof become unlawful in the EU, and so do climate neutral claims that rest only on buying offsets.
A policy analysis of the shift describes rules that explicitly ban generic environmental claims without evidence and expect a claim to rest on a full life cycle assessment or an equivalent science based method. A separate and broader Green Claims Directive, which would have hardened that assessment requirement further, was as of mid 2025 still only proposed and its future uncertain, so treat it as a direction of travel, not a live rule. Either way, the burden is shifting onto brands to defend what they say.
The 2026 question is no longer whether a brand can call itself sustainable. It is whether it can defend the claim.
Certifications that mean something
This is where you stop reading adjectives and start reading certifications. Two do most of the useful work.
GOTS, the Global Organic Textile Standard, sets hard thresholds. A guide to the standard explains that a Made with Organic label needs 70 per cent or more certified organic fibres, an Organic label needs 95 per cent, all chemical inputs must meet environmental and toxicological criteria, and compliance with International Labour Organization conventions is required. That last point matters: GOTS covers labour, not only fibre.
OEKO TEX STANDARD 100 does something different, and the difference trips people up. It is a harmful substance safety test, not an organic certification. The certifier explains that it tests textiles for harmful substances to make them safer for humans, with the 2026 update adding limits on substances including DBDPE, Dechlorane Plus, and n hexane. A shirt can be OEKO TEX certified and still be conventional cotton. It is safe to wear, not necessarily organic.
Beyond these two, look for genuine recycled content certification and traceability that names the supply chain rather than gesturing at it.
Buzzwords to interrogate
A newer set of terms is replacing the old ones, and they sound more technical, which makes them easier to trust and harder to check. Regenerative cotton, closed loop viscose, low water dye, mycelium leather. None is meaningless, but each needs backing. Ask which specific standard or third party verifies it. If the answer is the brand's own word, treat it the way you now treat eco friendly.
India's natural fibre advantage
India has a real story to tell here, and it is worth getting the facts right. The country is the sixth largest exporter of textiles and apparel globally, an industry that employs over 45 million people directly and shipped exports worth 34 billion US dollars in 2023. Where India genuinely ranks second is cotton: it is the largest cotton producer and the second largest cotton exporter in the world.
That base matters. A well made shirt in Indian grown natural fibre, cut to last, is a lower footprint choice than a synthetic bought and binned in a season, and it does not need a slogan to be one, which is part of how Sigma Code is made. GOTS and OEKO TEX are both widely used across Indian exporters, so the certifications are checkable, not exotic.
The one honest move: buy fewer, better, longer
Strip away the labels and one action beats all of them. Buy fewer garments, buy better ones, and keep them longer. A shirt worn two hundred times has a fraction of the footprint of five shirts worn forty times each, whatever the fibre. It starts with auditing your wardrobe to keep, repair, retire. No certification changes that arithmetic, and no brand can sell it to you as an upgrade, because it means you buy less.
A buyer's checklist for reading a claim
The EU is shifting the burden of proof onto brands
Analysis of the incoming rules shows generic environmental claims without evidence being banned outright, with defensible claims expected to rest on a full life cycle assessment or an equivalent science based method, so a brand has to substantiate what it prints, not only print it.
| Label | What it certifies | What it does not guarantee |
|---|---|---|
| GOTS Organic | 95 per cent or more organic fibre, chemical criteria, labour standards | That the finished garment is low carbon |
| OEKO TEX STANDARD 100 | No harmful substances above set limits | That the fibre is organic or recycled |
| Recycled content certification | A verified share of recycled material | That the item is otherwise responsibly made |
| Self declared "eco" | Nothing verifiable | Anything at all |
