UL Environment strives to protect human health and quality of life by establishing standards and certification programs to reduce exposure to chemicals and to improve indoor air quality. GREENGUARD standards are among the most stringent indoor air quality standards in the marketplace, and they are based on available standards and guidelines from national and international public health agencies. Not all GREENGUARD standards are ANSI standards. However, all GREENGUARD standards are documented, publicly available (along with test protocols) and have been reviewed by public health/toxicology advisory groups. Standards currently under development are listed below.
