Fair, unbiased, and credible
Find out how Green Seal certifies.


Green Seal bases its work on thorough, state-of-the-art scientific evaluations using internationally accepted methodologies. Product evaluations are conducted using a life-cycle approach to ensure that all significant environmental impacts of a product are considered, from raw materials extraction through manufacturing to use and disposal. Wherever possible, Green Seal standards cite international test methods for evaluating product performance or environmental attributes such as toxicity, and its procedures conform to international standards for ecolabelling.

In developing environmental standards and certifying products, Green Seal follows the Guiding Principles and Procedures for Type I Environmental Labeling adopted by the International Organization for Standardization (ISO 14024). Green Seal has played an important role in helping to shape policy at the national and international levels in the practice and use of ecolabeling and environmental product standards. We were instrumental in the development of ecolabelling policy standards of the International Organization for Standardization (ISO) under the ISO 14000 environmental management series. ISO standards are intended to harmonize standard-setting activities and to avoid international disagreements. Learn more about Green Seal's environmental standards.
