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).
