  • Vendors shall provide equipment containing low global warming potential (GWP) substitutes approved under the United States Environmental Protection Agency’s Significant New Alternative Policy (SNAP) program and permissible under state regulations.
  • Vendors shall provide products with a lower global warming potential to the maximum extent practicable where such products are cost-effective (using life cycle-climate performance (LCCP) and meet form, function, and utility requirements.
  • Vendors installing new refrigerators, freezers, or other appliances and removing old appliances shall certify that old products are properly recycled or disposed of.

Ultra low-temperature freezer (ULTs) policy:

  • Per the High-Efficiency Ultra-Low Temperature (HE ULT) Freezer Policy, all new ULT freezer purchases must be high-efficiency models.
    • Prior to purchasing, explore options such as sharing ULT freezers. If unable to do so, ensure that the ULT freezer being purchased is an appropriate size.
  • ULTs more than 10 years old should be decommissioned as soon as possible and adequately recycled by the WashU EH&S Department. Do not repurpose within the lab or donate elsewhere.
