A brief description of the time period on which the figures reported above are based :

This data includes expenditures from Stanford's primary waste contractor, UG2, as well as Stanford Athletics' waste contractor, TQM in 2020.

UG2 strives to be the industry leader in client-driven technology solutions, Green Cleaning programs, and other sustainability and energy services, as discussed on their website: https://ug2.com/ug2-sustainability-green-cleaning/

Additionally, per TQM's website, "TQM is a Bay Area Certified Green Business. We only clean with the greenest of chemicals and techniques available." See more details here: http://www.tqm.bz/

Finally, Residential & Dining Enterprises (R&DE), which operates in-house custodial services for approximately one-third of the campus, has moved to a Tersano-based green cleaning system. Tersano is water-based, so expenditures for this product are not included in either the total spend or the green spend figures above.
