Founded in 1989 in the USA, Green Seal is an independent organization that provides science-based environmental certification standards. Hundreds of products and services from major companies such as 3M, Benjamin Moore, and Andersen Windows have now been certified to meet Green Seal standards, and the number of major product categories covered by these standards has increased to more than 40.
