The Higg Index

The Higg Index is a suite of tools for the standardized measurement of value chain sustainability, and it is central to the SAC’s mission to transform businesses for exponential impact.

It is comprised of a core set of five tools that together assess the social and environmental performance of the value chain and the environmental impacts of products, including the Higg Facility Environmental Module (FEM), Higg Facility Social & Labor Module (FSLM), Higg Brand & Retail Module (BRM), Higg Materials Sustainability Index (MSI), and
Higg Product Module (PM).

Across topics such as water use, carbon emissions, and labor conditions, consumer goods brands, retailers, manufacturers, governments, NGOs, and consumers can use the Higg Index to inform their individual sustainability strategies and drive collective industry transformation. We developed the methodologies of the Higg Index over ten years using the latest scientific research, in partnership with SAC members, consultants, stakeholders,
and industry experts.

As an SME motivated by the ticking clock of climate change, we cannot spend our time re-inventing the wheel. Thanks to the collective knowledge present in the Higg Index tools and the generosity of the SAC community, we have been able to develop a deeper understanding of our impacts and take corrective action quickly.


Higg Index Verification

The SAC is continuously working to create comprehensive, credible, and scalable verification programs for each of the Higg index tools to improve the accuracy of the data reported. Verification improves the consistency, comparability, and credibility of Higg data. It also reduces the need for multiple, proprietary audits for facilities so that resources can be used in other areas, such as performance improvement.

To support the accurate measurement of environmental and social impacts using the Higg Index, the SAC is creating verification programs for each Higg tool. This is an essential part of the Higg framework because verified data provides companies with the trusted information they seek.

     Verification Quick Facts

  •  The Higg FEM verification program is available at scale in 100 countries
  •  Through the Social & Labor Convergence Program, Higg FSLM verification is offered in 30 countries worldwide
  • Higg BRM Verification Program is now available for brands and retailers to support credible communication
  • Higg Product Tools (Higg MSI and Higg PM) primary data is vetted by our third party gatekeeper and secondary data is independently peer reviewed

The Value of Verification

Every year, average FEM scores consistently improve, indicating a meaningful benefit to the
industry and our planet.

Facilities that invest in year-over-year completion of the FEM, that also take the extra step of verifying their results, are proven to have the largest average score increases. This demonstrates that when facilities are consistently submitting verified FEM results, they are seeing the greatest improvements. For example, the 245 facilities that consecutively completed verification for the past three cycles show the largest score improvements, increasing scores by an average 22% every year.

While the number of verified assessments for Higg FEM increases every year, there is still room for growth. For the past two cycles, more than 20% of facilities that completed the FEM went through the process of verification. As more global facilities complete and verify the FEM and other Higg assessments, we will continue to get a clearer understanding of the industry’s environmental performance. Increased participation in verification will improve industry-wide transparency and help companies identify opportunities
for improvement and collective action.
