Alta Refrigeration sues EPA over hydrofluorocarbon regulations in Georgia

Vice President JD Vance and EPA administrator Lee Zeldin toured the Alta Refrigeration plant in Duluth, Georgia, on Aug. 12, 2025, and announced a rollback of federal rules that limit the use of hydrofluorocarbons (HFCs) in cold‑storage equipment. The announcement came after months of lobbying by Alta and other manufacturers who argued that the rules would raise costs and hurt jobs. In May 2025 the EPA issued a final rule that gave cold‑storage makers several extra years to sell HFC‑based units before the phase‑down deadline took effect. Two weeks later Alta filed a lawsuit challenging the same rule, saying it still restricts the company’s products.

The case matters because HFCs are powerful greenhouse gases that the United States pledged to cut under the 2016 Kigali Amendment to the Montreal Protocol. The amendment calls for a 85 percent reduction in global HFC use by 2036. The Trump administration, which took office in 2025, argued that the original EPA schedule was too aggressive for American industry and threatened competitiveness. The administration’s rollback was framed as a win for manufacturers and for jobs in the Southeast. Critics warned that delaying the phase‑down would lock in higher emissions and make it harder for the U.S. to meet its climate targets. The EPA’s May rule tried to balance those concerns by granting a limited extension while keeping a long‑term phase‑down path.

Alta’s lawsuit claims the EPA failed to follow proper rule‑making procedures and that the extended timeline still imposes illegal limits on the company’s product line. The firm seeks a court order that removes any remaining HFC restrictions on its equipment. Environmental groups have filed amicus briefs, arguing the suit could undermine the nation’s climate commitments and set a precedent for other industries to challenge EPA authority. The case will be heard in the D.C. Circuit later this year. If the court sides with Alta, the EPA may have to rewrite the rule or grant broader exemptions, potentially slowing the nationwide HFC phase‑down. If the agency prevails, the existing schedule will stay in place, keeping the United States on its pledged path to cut HFC emissions over the next decade.
