Founded in 1989, Green Seal provides science-based environmental certification standards that are credible, transparent, and essential in an increasingly educated and competitive marketplace. 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 Certification ensures that a product meets rigorous, science-based environmental leadership standards. This gives manufacturers the assurance to back up their claims and purchasers confidence that certified products are better for human health and the environment.

Green Seal develops its standards with widespread input from industry, government, academia, and the public.

A new standard is broadly circulated for review and comment to a diverse group of stakeholders, including manufacturers, trade associations, universities, environmental and consumer groups, government officials, and the public.

When the final standard is published, we provide a written response to all the comments received, and open the standard to a formal appeal.

We periodically review and update our standards to reflect advances in technology and the marketplace.
