EPA Proposes Approval of New Climate-Friendly Refrigerants
In support of President Obama’s Climate Action Plan, the U.S. Environmental Protection Agency (EPA) is proposing to increase the options for refrigerants in the United States that offer better climate protection without harming the ozone layer. This is the agency’s first action that addresses refrigerants under the Climate Action Plan, which calls on EPA’s Significant New Alternatives Policy (SNAP) Program to identify and approve additional climate-friendly chemicals.
Under the authority of the Clean Air Act, EPA’s SNAP Program evaluates substitute chemicals and technologies that are safe for the ozone layer. This proposed action would expand the list of SNAP-approved substitutes to include more low-global warming potential (GWP) alternatives that can replace both the ozone-depleting substances and high-GWP hydrofluorocarbons (HFCs).
After receiving input from industry, environmental groups, and others, EPA is proposing to list additional low GWP hydrocarbon refrigerants in six refrigeration and air conditioning applications: stand-alone commercial and household refrigerators and freezers; very low temperature refrigeration; non-mechanical heat transfer; vending machines; and room air conditioning units. The proposal also adds one lower-GWP HFC (HFC-32) that has just one-third the GWP of the conventional refrigerants currently being used in room air conditioning units. These refrigerants are already in use in many of these applications in Europe and Asia.
