What is the Sustainable Apparel Coalition?
The Sustainable Apparel Coalition (SAC) was founded in 2009 as a collaboration between Walmart and Patagonia, two seemingly unlikely partners united by a shared vision: creating a universal standard for measuring sustainability in the apparel industry. Today, the SAC has grown to over 280 member organizations, including brands, retailers, manufacturers, NGOs, and academic institutions.
According to SAC’s 2023 Annual Report, member organizations represent more than 40% of global apparel and footwear production. This concentration means that Higg Index adoption isn’t just growing—it’s becoming the industry standard that factory owners cannot afford to ignore.
The Birth of the Higg Index
The Higg Index—named after the “Higgs boson” particle that helps give other particles mass—was designed to provide a common language for sustainability measurement across the industry. Just as the Higgs boson provides a foundation for understanding matter, the Higg Index provides a foundation for understanding sustainability performance.
The tool suite includes multiple modules:
– Facility Environmental Module (FEM): Measures environmental impact at manufacturing facilities
– Facility Social & Labor Module (FSLM): Assesses social and labor conditions
– Brand & Retail Module (BRM): Evaluates sustainability at the brand level
– Materials Sustainability Index (MSI): Rates the environmental impact of materials
For factory managers, the FEM is the most immediately relevant module, as it directly affects your ability to work with major brands and retailers.
Higg FEM Module Deep Dive: Understanding the Framework
The Eight Core Sections of Higg FEM 4.0
