The EU Green Claims Directive is the most significant development in environmental marketing regulation for a decade. For apparel brands making sustainability claims — organic, recycled, eco-friendly, sustainable — understanding this legislation is now a business-critical requirement.
What is the EU Green Claims Directive?
The EU Green Claims Directive, adopted in 2024 and to be transposed into national law by EU member states by 2026, prohibits vague, unsubstantiated and misleading environmental claims in business-to-consumer marketing. It applies to any brand making environmental claims about products sold in EU markets — including UK brands exporting to Europe.
What is Prohibited
The Directive prohibits claims that are: vague and generic ("eco-friendly", "green", "sustainable", "natural", "responsible"); unsubstantiated by recognised third-party certification; based on offsetting rather than actual product or process improvement; and comparative claims that cannot be substantiated against a defined baseline.
Under the Directive, a t-shirt labelled "sustainable cotton" without certification is non-compliant. A hoodie described as "eco-friendly" without specific, substantiated environmental claims is non-compliant.
What is Allowed
Specific, substantiated claims backed by recognised third-party certification are compliant. Examples of compliant claims:
- "Made with GOTS-certified organic cotton" — substantiated by GOTS third-party certification
- "Contains 50% GRS-certified recycled polyester" — substantiated by GRS certification and specific percentage
- "Produced in a SEDEX SMETA audited facility" — substantiated by independent audit
- "BCI Better Cotton sourced" — substantiated by BCI membership
The rule of thumb: if your environmental claim cannot be substantiated by a named, recognised third-party certification, you should not make it in EU markets after the Directive is transposed into national law.
UK Implications
The UK has its own Green Claims Code, enforced by the Competition and Markets Authority (CMA). While the UK is no longer subject to EU law post-Brexit, UK brands exporting to EU markets must comply with the EU Directive for those markets. The UK Green Claims Code mirrors many of the EU principles — unsubstantiated environmental claims are equally at risk of enforcement action in the UK.
How to Prepare Your Brand
- Audit all environmental claims in your marketing, labelling and product descriptions
- Remove or revise any vague, generic claims ("eco", "green", "sustainable" without qualification)
- Ensure all remaining claims are substantiated by a named, recognised certification
- Require current certification documents from your manufacturer for each claimed certification
- Train your marketing team on which claims are and are not substantiated
