UMass Amherst uses green products for general cleaning including floors, walls, carpets, doors, desktops, etc. Currently there are no disinfectants that are green approved, so bathrooms cannot be totally green cleaned at this point.

One UMass department, Auxiliary Services, received the OS1 Green Certification for its cleaning program. The certification recognizes organizations that are dedicated to cleaning for health and reducing environmental harm. The achievement of this certification means that Auxiliary Services is actively reducing hazardous chemicals and waste, reusing cleaning materials rather than sending them to the landfill, cleaning safely, and effectively recycling. Auxiliary Services is the first cleaning operation in the State of Massachusetts to achieve this certification.
