The Preferred Fiber and Material Matrix is an interactive tool to guide sourcing decisions.

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.

Goals

We’re helping brands big and small better understand their impacts.

The PFMM shares data and guidance on over 65 of the most common materials, programs, and initiatives. We’ve taken advantage of the expertise of others in the sector to help us to refine the tool so that it combines qualitative and quantitative data and is an essential decision-making asset for the industry.
