AHRI and NRDC join forces to urge US 2025 deadline for R134a in new chillers

AHRI and Natural Resources Defenses Council issue joint letter supporting EPA SNAP proposal to prohibit R134a, R410A and R407C in new chillers from 2025

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the Natural Resources Defense Council (NRDC) have issued a joint letter to the US Environmental Protection Agency (EPA) in support of changing the status of certain refrigerants used in liquid chillers under the Significant New Alternatives Policy (SNAP) program effective January 1, 2025.

The two groups said they took this action following ’lengthy discussions’ on the importance of moving beyond high-global warming potential (GWP) refrigerants used in chillers and consideration of factors such as the safety of alternatives, the continued improvement of system efficiency, reasonable product development timelines, and the avoidance of market migration. The effective date was negotiated with those factors in mind.

The two bodies emphasised their belief that the eight year window will provide adequate time for manufacturers to develop low-GWP alternatives that meet all the required safety and technical standards.

 AHRI President & CEO Stephen Yurek said: “This is another example of industry and efficiency advocates working together toward environmental progress, while allowing sufficient time and predictability for manufacturers. We are grateful to the members of AHRI’s Liquid Chillers Product Section, who worked diligently to reach this agreement.”

AHRI said the EPA is expected to decide in the coming months whether or not to accede to this consensus recommendation.
