The Higg Index

Developed by the Sustainable Apparel Coalition, the Higg Index is a suite of tools that enables brands, retailers, and facilities of all sizes — at every stage in their sustainability journey — to accurately measure and score a company or product’s sustainability performance. The Higg Index delivers a holistic overview that empowers businesses to make meaningful improvements that protect the well-being of factory workers, local communities, and the environment.

Product Tools

Higg Product Tools help brands, retailers, manufacturers, and academics understand the environmental impacts of apparel, footwear, and textiles. There are two Higg Product Tools: the Higg Materials Sustainability Index (Higg MSI) and the Higg Product Module (Higg PM).

Facility Tools

Higg Facility Tools measure environmental and social sustainability impacts in manufacturing facilities around the world. There are two Higg Facility Tools: Higg Facility Environmental Module (Higg FEM) and Higg Facility Social & Labor Module (Higg FSLM).

Brand & Retail Tool

Global brands and retailers use the Higg Brand & Retail Tool to assess the sustainability of product lifecycles, the environmental performance of their operations, and the social impacts across the value chain.

Improvement in Higg Facility Environmental Module Scores

Every year, we have seen Higg Index scores improve, a meaningful benefit to the industry and our planet. This graphic shows average yearly scores for factories around the world that use the Higg Facility Environmental Module (Higg FEM).


To build consistency, credibility, and comparability of Higg Index scores, the SAC has created verification programs for each of its tools. The first verification program for the Higg FEM is available at scale. The SAC is currently piloting a verification program for the Higg BRM.

Higg Index Transparency

The Higg Index enables and encourages brands, retailers, and manufacturers to become transparent by communicating clear, trustworthy, and meaningful sustainability information publicly. Transparency can allow companies to form stronger value chain partnerships. It helps designers and developers to make more sustainable products. And it empowers consumers to make more informed purchasing decisions.

Higg Index transparency will ensure accountability and enable the apparel industry to thrive responsibly. To support members as they become more transparent, the SAC provides communication toolkits that offer transparency guidelines and support.

The Higg Index is an operational excellence assessment tool. With the Higg Index, you get collective direction and harmonized, aggregated results. What is our overall supply chain footprint? What are all the products that make up that footprint? How do we prioritize potential opportunities to make these products in a better way to lower their footprint? If the entire industry works in that way, then we can set long-term strategic goals to make collective improvements and have significant meaningful change.
