Companies can manage their climate impact through the materials they use.


The fashion and textile industry gets most of its materials from farming, forests, or fossil fuels. Exploring options that respect our planetary boundaries is a critical lever that companies can pull to reduce their climate impact. Instead of relying on conventional fibers, brands should explore organic, regenerative, recycled, or other more responsible alternatives instead.

Materials portfolio in numbers


Preferred materials’ share of total material use.


Materials produced on land under improved practices.


Year-on-year increase in the volume of preferred materials sourced.


Taking a portfolio approach means exploring multiple options.

There are no silver bullet solutions to systems change. That’s why we encourage companies not to focus their sustainability efforts on a single fiber, but to start integrating preferred options across all the materials that they use. Taking a portfolio approach means recognizing that there might not be one single fiber, material, or program that meets all your needs and that your selection might change over time.
