The EU laws, international test methods and sustainability certifications that actually govern textile claims and performance sportswear.
Use this reference to look past brand marketing and verify the rules, test standards and certifications behind durability, recycled content and green claims.
The European Commission's 2030 policy framework for textiles sold in the EU.
Sets long-term targets for textile durability, recyclability, mandatory recycled-fibre content, and reducing the environmental footprint of textiles placed on the EU market. It is the high-level policy that the Ecodesign for Sustainable Products Regulation and the Green Claims rules implement.
The EU law in force from September 2026 that bans vague environmental claims.
Member States must enforce this directive from September 2026. It prohibits generic, unsubstantiated claims like 'eco-friendly', 'green' or 'sustainable' on product pages unless they are backed by detailed, verifiable evidence. Note: the separate Green Claims Directive, which would have added a stricter ex-ante verification layer, was paused by the Commission in 2025.
The framework introducing Digital Product Passports and minimum requirements for textiles.
ESPR establishes mandatory ecodesign requirements for products placed on the EU market, including textiles. It introduces Digital Product Passports and sets minimum thresholds for recycled content, durability and reusability — making it a key compliance layer for sportswear brands selling in Europe.
The sweating guarded-hotplate test behind Rct/Ret thermoregulation figures.
ISO 11092 measures a fabric's resistance to dry heat (Rct) and evaporative heat transfer (Ret) using a sweating guarded hotplate. These numbers are what brands quote when they claim a garment is breathable or thermally efficient — lower Ret means better moisture-vapour transmission.
The test behind OMMC and wicking-performance scores for textile fabrics.
AATCC Test Method 195 evaluates how liquid water spreads through a fabric in multiple directions. It produces the Overall Moisture Management Capacity (OMMC) score used to rank how quickly a fabric wicks, spreads and dries sweat — central to claims about moisture-wicking performance.
Third-party verification of recycled content and chain of custody.
Administered by Textile Exchange, GRS verifies recycled content, chain of custody, and social and environmental criteria. It requires a higher minimum recycled-content threshold and adds environmental and social criteria beyond the baseline Recycled Claim Standard (RCS).
Independent testing for harmful substances in garments and textiles.
OEKO-TEX STANDARD 100 tests textile products for regulated and non-regulated substances that may be harmful to human health. It is a finished-garment safety certification, not a sustainability or durability claim, but it is widely used as a baseline assurance label.
Chemical-input and manufacturing-process certification across the supply chain.
bluesign audits chemical inputs, manufacturing processes and environmental performance from raw materials to finished product. It focuses on eliminating harmful substances at the input stage and improving resource productivity, making it a process-level certification rather than a single-fibre claim.
