Green Seal Standards

  • Who decides what requirements go into the standards?

    The requirements in our standards are the result of research by our environmental scientists, who identify the major impacts of a product category on health and environment and set requirements that represent leadership in that product category. We then get input from a broad variety of stakeholders to ensure that our criteria are challenging and achievable, and accurately capture the environmental impacts and the current market practice.

  • Who are the stakeholders participating in the standard development process?

    We invite manufacturers, raw material suppliers, distributors, retailers, product users, purchasers, regulators, researchers, trade groups, health and environmental groups, other NGOs, advocates and anyone else who may be affected by the products or their use.  Our process is open to the public and anyone who wants to participate is welcome!

  • How often does Green Seal update the standards?

    Green Seal re-visits each standard every three years or as needed. If we notice a significant change in the market, or if a stakeholder highlights a major shift in the market, and we see that shift being adopted by a significant minority (15-20% of the market), then we will announce a Standard Revision.
