Our industry knowledge and standards help manufacturers, purchasers, and end users alike make responsible choices that positively impact business behavior and improve quality of life. Green Seal works with manufacturers, industry sectors, purchasing groups, and governments at all levels to "green" the production and purchasing chain. We utilize a life-cycle approach, which means we evaluate a product or service beginning with material extraction, continuing with manufacturing and use, and ending with recycling and disposal. Products only become Green Seal certified after rigorous testing and evaluation, including on-site plant visits. 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 standards has increased to more than 40. Today, we have established a significant market among large institutional purchasers, including government agencies, universities, and the lodging and architectural building industries. We actively advise and assist these institutions and industry sectors in their efforts to green their purchasing, operations, and facilities management functions.
