Green Seal

A non-profit that provides third-party certification for a wide range of products, including paints, adhesives, lamps, chillers, windows, cleaners, and occupancy sensors. Green Seal follows the ISO process for open standard development but is not ANSI-approved. Following ISO requirements, Green Seal considers impacts over the entire life cycle of a product in developing a standard. It then develops criteria relating to the most significant impacts for which roughly 20% of existing products have superior performance. Green Seal reviews its standards every three years and updates them when it sees a shift in the market. Green Seal’s certifications are based on data from accredited laboratories and audits of manufacturing facilities. https://healthymaterialslab.org/tool-guides/hml-resources
