Mandate EPR for all textile producers selling in the UK
Implement tiered fees based on circular design, durability, fiber composition, and production methods
Generate an estimated £150 million annually to fund circular economy infrastructureUKFT (ukft.org)
Align the UK with EU (EPR by 2027), Australian, and US initiativesFashion Declares (fashion-declares.org)

Provide comprehensive lifecycle information via QR codes
Include data on materials, carbon footprint, and recyclability
Enhance supply chain transparency and traceability
Support more effective recycling and waste managementFashion Declares (fashion-declares.org)

Green Claims Enforcement: From April 2025, the Digital Markets, Competition and Consumers Act 2024 (DMCCA) strengthens anti-greenwashing measures:

Brands must hold robust evidence for sustainability claims
