We are revolutionizing our standards system

In 2021, we began a sweeping revision of our standards framework with the aim of developing a harmonized system that incorporates outcomes aligned with our climate and nature strategy. Known as “the unified standard” during its development, the Materials Matter Standard was released with its official name for its pilot testing version. Bringing our standards under this framework will let us track and communicate progress more efficiently and effectively across all of the fibers and materials in the scope of our certification system, while increasing the value for participants. You can learn more about the development of the Materials Matter Standard in our project plan.


Explore the pilot criteria

Following invaluable feedback from stakeholders, the Materials Matter Standard Pilot Version V1.0 was released publicly on June 4, 2024. This version will be used for pilot testing the feasibility of the criteria in the field and is not effective, meaning it is not possible for companies to get certified to this version.

Standards are crucial to help us reach our climate and nature goals

Adopt best practices

Drive greater adoption of best practices in fiber and material production and sourcing, contributing to sustainability outcomes.

Positively impact our planet

Reduce greenhouse gas emissions, improve soil health, increase biodiversity, and improve the use and quality of water.

Support key impact areas

Encourage best practices in the key impact areas for animal welfare, human rights and livelihoods, chemical management, and waste reduction.


Our focus area is fiber and material production

Certified materials will be tracked through the supply chain with our pre-existing chain of custody standard, the Content Claim Standard (CCS). While the CCS continues to provide the mechanism for tracking and handling of the certified inputs through to the finished product, the Materials Matter Standard impact criteria focus on raw material production and initial processing.

We make decisions in collaboration with interested and impacted stakeholders

Alongside our own procedures for standard setting, accreditation, and certification, we also follow the ISEAL Codes of Good Practice. Our standards team is leading the revision process, with help from the International Working Group (IWG), which reviews, discusses, and guides decision-making. Previous IWGs have been established for single standards, but with this transition we are working with one IWG to review all the related fibers and materials in scope for the Materials Matter Standard, while connecting to smaller subject matter expert groups that inform its members.

IWG members

The International Working Group (IWG0 is the group of stakeholders actively engaged in the development or revision of a standard. IWG members are approved by a designated review committee. All IWG members are required to sign a charter (IWG charter) Indicating their commitment to the goals of the standard and the time need to be engaged in the process. Together with the Textile Exchange secretariat, the IWG reviews, discusses, and guides decision-making on how to incorporate scope topic areas in the standard. The IWG approves the draft versions of the standard before they are ready for public consultation as well as the final standard before it is published. 

Representation is limited to no more than 24 members that bring the following knowledge and perspectives.
