Certification Types

GREENGUARD Indoor Air Quality Certification

  • The very first voluntary North American indoor air quality product certification created specifically for commercial building products, this certification requires that products meet stringent chemical emissions requirements for over 360 VOCs, plus a limit on the total of all chemical emissions combined. Products undergo routine monitoring and annual retesting to ensure continued compliance with the GREENGUARD Children & Schools standard.

GREENGUARD Children & Schools Certification

  • Developed with the specific health sensitivities of children in mind and based on key criteria from public health agencies, this certification sets some of the world’s most stringent emission limits on over 360 chemicals, a limit on total chemical emissions, and a limit on phthalate emissions. Products undergo routine monitoring and annual retesting to ensure continued compliance with the GREENGUARD Children & Schools standard.

GREENGUARD Select Certification

  • GREENGUARD Select Certification offers manufacturers increased flexibility—and selection—when it comes to communicating their indoor air quality performance to the marketplace. Environment-specific product emissions testing, as well as environment-specific certification marks, provide greater clarity for specifiers, consumers, and other purchasers. Manufacturers whose product achieves GREENGUARD Select Certification will have the opportunity to test and certify to a residential, commercial, healthcare, or educational environment—depending on the product’s application.
