The Environmental Protection Agency’s new SNAP program is acronym for ‘The Significant New Alternative Policy.’ It’s original purpose was to monitor, regulate, and to eventually phase out O-Zone depleting gases such as R-12 and R-22. R-12 was phased out in 1994 and R-22 was phased out in 2010.
The SNAP program is now being used to find replacements for HFC refrigerants such as R-134a, R-404A, and R-410A. These HFC refrigerants have a high global warming potential and contribute to Global Warming. The EPA’s SNAP program is looking at all refrigerant alternatives and approving the ones that they feel have the most promise.
