What is the Center for Green Cleaning and Sustainability?

Originally founded in 2006 as the Green Cleaning Network, The Center for Green Cleaning and Sustainability (TC4GCS) is proud of its contribution to the greening of the cleaning industry. Some of our proudest contributions have led to:

  • Reduced use of hazardous ingredients commonly found in conventional cleaning chemical products including formaldehyde, ammonia, 2-butoxyethanol (butyl cleaners), and nonylphienol ethoxylated surfactants; while encouraging transparency, green chemistry and innovative technologies.
  • Reduced use of sanitary paper products made from 100% virgin tree fiber that were harvested in an unsustainable manner and bleached using elemental chlorine; while encouraging products sustainably harvested, made with a high percentage of post-consumer recycled content and/or other alternative fibers.
  • Reduced the use of plastic can liners made exclusively from virgin plastic resin; while encouraging more efficient use and sizing of bags, and a high percentage of post-consumer recycled content.
  • Adopted public procurement requirements for environmentally preferable products in 31 states and developed Green Cleaning programs for numerous organizations including the US Green Building Council, International Facility Managers Association, Healthy Schools Campaign, Hospitals for a Healthy Environment, and Green Sports Alliance.

We make resources and tools for implementing Green Cleaning available to cleaning professionals, facility and property managers, policymakers, advocates, third-party certifiers, and other organizations concerned with environmental health, and to get them talking about how to use them. In the process, we facilitate learning, assist with problem-solving and promote the adoption of Green Cleaning in schools and universities, health care, sport facilities, government and commercial office buildings, hospitality and lodging, retail, multi-family and many other institutional and commercial settings.
