Materials Sustainability Index
Base Material Scores
The Materials Sustainability Index (MSI) is a cradle-to-gate index informed by life cycle assessment (LCA) derived inventory data to engage product design teams and the global supply chain of the apparel and footwear products in environmental sustainability. The MSI was originally developed by Nike and is a result of more than eight years of materials research and analysis. In July 2012, it was adapted by the Sustainable Apparel Coalition (SAC) and incorporated into the Higg Index, a tool that measures the environmental and social performance of apparel and footwear products.
The MSI web tool integrates and visualizes the data and methodology of the MSI (Base Material Scores only) and enables the SAC and stakeholders to submit, review, publish and compare material data and scores. The complete MSI dataset is open source and the vision is to evolve this tool into a "Federated Wiki" that will further empower collaboration and data transparency across the apparel and footwear industry.
