Refrigerant Management Program (RMP)
Refrigerants Regulated

Refrigerants regulated under the Refrigerant Management Program include any refrigerant that is an ozone depleting substance (ODS) as defined in Title 40 of the Code of Federal Regulation, Part 82, or any compound with a global warming potential (GWP) value equal to or greater than 150. The table below summarizes common high-GWP refrigerants regulated under the Refrigerant Management Program (highlighted in yellow) as well as alternative substitute refrigerants that are not regulated under the Refrigerant Management Program. The table only provides common refrigerants; it does not list all possible refrigerants that are regulated under the Refrigerant Management Program or all possible alternatives to these refrigerants

Note that GWPs listed here need to be updated to AR 4.

Any refrigerant not listed MUST be checked elsewhere to see if it has GWP 150 or above.
