Our History

Green Seal was a pioneer in the ecolabeling movement. When we were founded in 1989, there were no other nonprofit environmental certification programs in the United States. Through the years, we have led companies to improve the sustainability of their products, driven environmentally preferable purchasing (EPP) among governments and institutions around the world and expanded the use of safer products in your schools, workplaces and homes.
