The Greener Product Certification Seal demonstrates that a product has been evaluated against the LEED, LEED for Homes and NAHB green building standards using internationally recognized third-party certification organizations, laboratory test results and/or other supporting documentation.

Products in twenty four building products categories are evaluated using seven environmental qualifiers namely energy (conservation and renewable), regionally produced materials, air quality, certified wood, recycled content, reused and renewable materials. Significant environmental impacts are considered and products are evaluated from raw materials extraction through manufacturing to use and disposal. Environmental claims are reviewed and verified through third-party certification and/or supporting documentation stating that products have been accepted for USGBC and/NAHB certified projects.

Manufacturers first complete an application form and once the information has been received products are evaluated against the aforementioned standards. Only once a product has been deemed to be in compliance will it be awarded the Seal.

Certified products are then listed and searchable on the Greener Products site.
