Nike, Patagonia, Under Armour join new microfibre pollution alliance

Nike, Patagonia, and Under Armour join a new alliance to address microfibre pollution in the apparel supply chain.

What happened

Nike, Patagonia, Under Armour, Lululemon, Cotopaxi and REI Co-op are among the founding members of a new industry initiative focused on reducing microfibre pollution across the apparel supply chain.

Why it matters

The Microfibre Action Alliance (MAA), launched by The Nature Conservancy (TNC), encourages apparel companies to collaborate the acceleration, adoption and scaling of evidence-based solutions to microfibre shedding.

The alliance will work with participating companies to identify where microfibre pollution occurs within their supply chains, test interventions and share findings with the wider industry. TNC said the aim is to build a practical, scalable roadmap that can support wider adoption of effective solutions.

Microfibres are small particles shed by synthetic and natural textiles during production, use and wear, with synthetic microfibres being among the most common forms of microplastic pollution found in nature. Treated natural fibres such as cotton and wool can also contribute to microfibre pollution.
