Preferred Fiber and Materials Matrix

The Preferred Fiber and Material Matrix (PFMM) assesses the trade-offs of different sustainability certifications, initiatives, and branded materials. It was conceived by Gap Inc. to help their designers and product teams understand the impact of their fiber and materials choices. We were given responsibility and ownership of the tool in 2020.

NEXT STEPS

Updating the tool

We are currently building out the Preferred Fiber and Materials Matrix so that it can better help the industry define what constitutes a preferred fiber or material, expanding on the Initial Guidance we provided in 2023. 

The next version will go beyond its current scope and apply to a range of programs, including standards systems, branded fibers, and improvement programs.  

In early 2025, we will launch a self-assessment process for programs that want to be listed in the tool, with the results third-party verified before being published. We are undertaking this change is to enable a more efficient process of including programs in the tool. Please note that no further programs will be added to the PFMM in 2024.
