The U.S. Court of Appeals stopped the EPA’s ban on high global warming potential HFC refrigerants last year, but that may just be a pause in the switch from HFCs to environmentally friendly replacements.
Makers and users of high-GWP HFC refrigerants prepared for years in anticipation of the now-vacated Obama-era EPA SNAP regulations, and it’s likely a matter of time before either the U.S. Supreme Court, a patchwork of state regulations or ratification of the international Kigali Amendment brings an end to HFCs.
