Organic Cotton T-Shirts: Selling Them Without Greenwashing
By The Velocity Wear Team
Organic cotton t-shirts get over a thousand UK searches a month, and sustainability sells. But since the Digital Markets, Competition and Consumers Act gave the Competition and Markets Authority power to fine businesses directly for misleading consumers, vague green claims on clothing aren't just bad manners any more. They're a genuine business risk.
What organic actually means
Organic cotton is grown without synthetic pesticides and fertilisers, under certified farming standards. The word on its own proves nothing. What backs it up is certification through the supply chain. The Global Organic Textile Standard (GOTS) and the Organic Content Standard (OCS) are the two most widely recognised.
- GOTS covers organic fibre content plus environmental and social criteria through processing.
- OCS verifies the amount of organic material in a product, but not processing criteria.
- Both rely on certification documents that follow the goods.
The CMA Green Claims Code in plain terms
The code sets out how environmental claims should work. Simplified:
- 1Claims must be truthful and accurate.
- 2They must be clear and unambiguous.
- 3They mustn't omit or hide important information.
- 4Comparisons must be fair and meaningful.
- 5They must consider the full life cycle of the product.
- 6They must be substantiated.
Words to be careful with
- Sustainable, eco-friendly and green, used without explanation.
- Organic, unless the product is certified and you can show it.
- Carbon neutral, unless you can evidence exactly how.
- Ethical, without specifics about what that means.
Specific, evidenced statements are safer and more persuasive: made with certified organic cotton, with the certificate available on request.
Ask your supplier the right questions
If you want organic t-shirts, ask what certified options are available for your order, and ask for the certification paperwork before you mention it on your product page. If a supplier can't provide documents, don't make the claim. That applies to us as much as anyone.
Sustainability you can say honestly
There are truthful angles that don't need certificates. Ordering the right quantity instead of overproducing. Pre-orders to avoid waste. Durable shirts that last longer. Care instructions that extend a garment's life. These are real, and they're claims you can stand behind.
Labelling basics still apply
Garments sold in the UK need accurate fibre composition labelling. If a tee is a blend, say so. Organic cotton blended with recycled polyester isn't a 100% organic cotton tee.
Keep your evidence organised
If you do sell certified organic tees, keep the certificates, invoices and supplier details together and linked to each product. If a customer or the CMA ever asks, you want to be able to show the paper trail in minutes. Update your product pages if a supplier or fabric changes, because a claim that was true for last season's shirts isn't automatically true for this season's.
Talking about sustainability without overclaiming
Be specific: say what's certified, what isn't, and what you're working on. Customers trust brands that admit they're on a journey more than brands that claim to be perfect.
Labelling organic blends
If a tee blends organic and conventional fibres, state the percentages accurately on labels and product pages.
