SGS is functioning to help clothing manufacturers prove sustainability to consumers using the Higg Index FEM Module and the FSLM Module. SGS has a range of services to help companies develop and manage comprehensive programmes related to better environmental sustainability. It offers verification services according to SAC Higg verification protocols. Manufacturers and suppliers of clothing can no longer ignore the demand from consumers for sustainable production methods. To help stakeholders, the Sustainable Apparel Coalition (SAC) released the third iteration of its Higg Index Facility Environmental Module (FEM) in 2017. The Higg Index FEM helps businesses assess their environmental sustainability. In 2018, the SAC also released the Facilities Social and Labour Module (FSLM) allowing businesses to assess their social performance.
