GREENGUARD Joins The UL Environment Team

September 8, 2011

Early in February 2011, the sister certification of TerraChoice Environmental Marketing’s EcoLogo Program, UL Environment, acquired Air Quality Sciences (AQS) and its certifying body, the GREENGUARD Environmental Institute (GEI).

AQS and GREENGUARD are the market leaders in North America for product emissions testing and third-party indoor air quality (IAQ) certification.

This means that EcoLogo, AQS, UL Environment, TerraChoice and GREENGUARD are all part of the same UL global network working together to provide leading environmental evaluation, consulting and certification services to a constantly evolving green product marketplace.

EcoLogo joined the UL global network in 2010.

The EcoLogo Program has had a longstanding relationship with GREENGUARD and AQS.

This new acquisition means EcoLogo clients will have even better access to world-leading expertise in IAQ and enhanced capabilities in testing and validating environmental leadership.

EcoLogo looks forward to sharing more about these new developments over the coming months.
