Green Seal is an independent, non-profit, science-based, standard development and certification body based in Washington, DC. Its mission is to promote the manufacture, purchase, and use of more sustainable products and services. Green Seal’s flagship program is a voluntary certification program that features a certification mark– an ecolabel – to demonstrate that a product or service is safer for human health and the environment. Green Seal’s flagship program is voluntary certification of products and services to its standards.
The organization uses the Green Seal Certification Mark – an ecolabel – to award certification after evaluating a product or service. The Green Seal Mark, which is registered with the U.S. Patent and Trademark Office, is used to demonstrates that a product or service is safer for human health and the environment and has met a high level of functional performance.
Green Seal is a U.S. member and co-founder of Global Ecolabelling Network (GEN) which consists of 28 international ecolabeling programs, including Germany's Blue Angel, the EU Ecolabel and the Nordic swan. Green Seal meets the Criteria for Third-Party Certifiers of the United States Environmental Protection Agency  the requirements for standard development organizations of the American National Standards Institute,  and the guidelines for ecolabeling programs of the International Organization for Standardization (ISO 14020 and 14024).  The Green Seal Mark is registered with the U.S. Patent and Trademark Office.
Since its founding in 1989, Green Seal has developed environmental standards for more than 300 categories of products and services. To supplement its certification program, Green Seal published a series of buying guides for purchasers in the 1990s (the Choose Green Reports) and at that time began providing technical assistance to Federal, State, and local governments and other institutions to green their purchasing, operations, and facilities management. In the early 2000s, the certification program focused primarily on building maintenance. In 2006 the US Green Building Council LEED rating system included several Green Seal standards in their criteria. Practice GreenHealth, the AASHE STARS program, and the Green Ribbon Schools Program of the U.S. Department of Education, among others, reference Green Seal standards. In 2010 a study by the Responsible Purchasing Network noted that the Green Seal was recognized by 95% of purchasers and used by 76%.
Standards and certification
Green Seal’s sustainability standards identify requirements which products or services must meet to achieve Green Seal certification. The standards are based on a life cycle approach, considering various impacts including those from raw materials extraction, manufacturing, use, and re-use or disposal. The evaluation process includes review of data; assessment of labeling, marketing, and promotional materials; and on-site auditing. Products or services become certified and awarded the Green Seal Mark only after these evaluations are completed, and regular compliance monitoring is required to maintain certification.
Green Seal currently has standards and provides certification for products and services in the following categories:
- Building & Construction Products
- Cleaning Products & Services
- Company Certification
- Hotels & Lodging
- Household Products
- Institutional Products
- Lighting & Control Products
- Paint & Coating Products
- Paper Products
- Personal Care Products
- Restaurant & Food Services
- Vehicles & Vehicle Maintenance Products
Green Seal provides a list of all Green Seal standards and all Green Seal-certified products and services on its website, www.greenseal.org.
