GREENGUARD Certification emissions limits were first used as purchasing specifications for the EPA and the state of Washington for furniture and commercial building products. GREENGUARD Certification criteria have been the basis for the LEED credit for low-emitting furniture since 2002. Office furniture products that are GREENGUARD Certified are also compliant with the Business and Institutional Furniture Manufacturers Association (BIFMA) X7.1 standard and BIFMA e3 credit 7.6.1.
