Green Seal is a U.S.-based non-profit organization that certifies products and services that meet high environmental standards. Iwas founded in 1989 by a group of environmental leaders who were concerned about the lack of environmental standards for products and services. Green Seal sets standards for a wide range of products and services, including cleaning products, personal care products, food, and building materials.These standards are based on a life-cycle approach, which means that they consider the environmental impact of a product or service from the extraction of raw materials to the disposal of the product or service at the end of its life. They are also rigorous and are regularly updated to reflect the latest scientific research.
