UL Environment purchases AQS, GreenGuard certification

NORTHBROOK, ILL.—UL Environment, a business unit of UL (Underwriters Laboratories), has reached agreement with Air Quality Sciences (AQS) to acquire AQS and its certifying body, the GreenGuard Environmental Institute. AQS and GreenGuard are among the market leaders in North America for product emissions testing and third-party indoor air quality certification.

AQS helps manufacturers identify the chemicals being emitted from their products using state-of-the-art equipment and testing laboratories. GreenGuard certification helps manufacturers communicate their sustainability message to the marketplace by providing assurance that their products have been independently evaluated for low chemical emissions.

“This acquisition combines AQS’s world-class technology and expertise, as well as GreenGuard’s brand recognition and scientific rigor, with UL’s trusted history of standards development, testing and compliance to create a more comprehensive solution for testing and certification,” said Steve Wenc, president of  UL Environment. “Together, we’ll help consumers, regulators and other interested parties make informed product purchases by providing clarity around indoor air quality claims.”

“By joining forces with such a recognized and reputable brand as UL, we are confident that we will boost consumer confidence in the green product marketplace,” said Dr. Marilyn Black, founder of the GreenGuard Environmental Institute and chairperson at AQS.
