The 2025 Recycled Polyester Challenge was designed to accelerate change.

Polyester is the most popular material used in the fashion and textile industry. This reliance on virgin fossil-based materials is damaging to our environment, but there’s no other fiber on the market today that could absorb this demand. That’s why we’re challenging the fashion and textile industry to increase the market share of polyester that comes from recycled sources from 14% in 2019 to 45% in 2025.


We launched this joint initiative with the UNFCCC.

In April 2021, we teamed up with the United Nations Framework Convention on Climate Change’s Fashion Industry Charter for Climate Action to launch the 2025 Recycled Polyester Challenge. Together, we’re setting out to spur a shift in the market towards the uptake of recycled polyester and its associated reduction in greenhouse gas emissions.


Our goal is to reduce the industry’s reliance on fossil-based resources.

The 2025 Recycled Polyester Challenge calls on companies to commit to sourcing from 45% to 100% of their polyester from recycled sources by 2025. Our goal is to stop new fossil-based synthetic fibers from entering the system, rather than substitute other material categories or justify increased industry growth.
