The NRDC, along with a coalition of states led by New York, declared victory in their lawsuit against the EPA.

The two groups took this action following lengthy discussions on the importance of moving beyond high-GWP (global warming potential) 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.
