In early 2012, the U.S. Environmental Protection Agency (EPA) gave Significant New Alternatives Policy (SNAP) approval to three hydrocarbon (HC) refrigerants in some applications. That could well have laid the groundwork for wider use of a type of refrigerant that is used in Europe and Asia on a much broader scale.
