The GREENGUARD Certification Program (formerly known as GREENGUARD Indoor Air Quality Certification) gives assurance that products designed for use in indoor spaces meet strict chemical emissions limits, which contribute to the creation of healthier interiors. Achieving GREENGUARD Certification gives credence to manufacturers’ sustainability claims, backing them with empirical scientific data from an unbiased, third-party organization. GREENGUARD Certification is part of UL Environment, a business unit of UL (Underwriters Laboratories). GREENGUARD Certification helps manufacturers create--and helps buyers identify--interior products and materials that have low chemical emissions, improving the quality of the air in which the products are used. UL Environment acquired GREENGUARD in 2011, further advancing its mission of promoting global sustainability, environmental health, and safety. UL Environment's GREENGUARD Certification program helps manufacturers create--and helps buyers identify and trust--interior products and materials that have low chemical emissions, improving the quality of the air in which the products are used. All certified products must meet stringent emissions standards based on established chemical exposure criteria. GREENGUARD Certification is broadly recognized and accepted by sustainable building programs and building codes around the world. Additionally, the GREENGUARD Product Guide serves as a free online tool for finding certified low-emitting products for offices, hospitals, schools, homes, and more.
