UL Environment, a subsidiary of the product safety certification organization Underwriters Laboratories (UL), has acquired Air Quality Sciences (AQS) and its certifying body, the Greenguard Environmental Institute. Under the acquisition, Greenguard will retain its name, and its certification program names will remain unchanged as well.
AQS aims to help product manufacturers identify the chemicals emitted from their products through the use of testing laboratories, while Greenguard certification aims to help manufacturers communicate their sustainability message to the marketplace regarding low chemical emissions. Its marketing efforts include the Greenguard certification mark and Greenguard product guide.
