GOALS

Accelerating the adoption of more responsible materials is just the first step

Our aim is for more sustainably sourced cotton and recycled polyester to replace their conventional counterparts, rather than substitute other types of materials or justify increased industry growth. This, coupled with investment in innovation, the scaling of existing solutions, and an emphasis on degrowth, can help us reach our Climate+ goals on time.

HOW IT WORKS

We’re tracking progress, together

Each year, participating companies report their cotton or polyester consumption through our Materials Benchmark, allowing us to track progress towards the 2025 goals. All the information is anonymous and aggregated across all the participants in the annual challenges dashboard. Your company information will never be singled out and published without your company’s explicit request or consent.
