WASHINGTON (AP) — The Trump administration on Thursdayloosened federal rulesthat require grocery stores and air-conditioning companies to reduce greenhouse gases used in cooling equipment, a step President Donald Trump said would help lower grocery costs.

Trump, at a White House ceremony, said the action by the Environmental Protection Agency would “substantially lower costs for consumers” by delaying costly restrictions that limit the type of refrigerants U.S. businesses and families can use.

The move torelax the Biden-era ruleson harmful pollutants known as HFCs emitted by refrigerators and other appliances was the latest attempt by the Trump administration to try to address rising voter concerns over the cost of living ahead of pivotal elections in November.

It is not clear how much or how quickly the loosening of the refrigerant rule might impact grocery prices. Industry groups said the move could even raise prices because manufacturers have already redesigned products, retooled factories and trained workers to build and service next-generation refrigerant equipment.

Inflation in the United Statesincreased to 3.8% annuallyin April, amid price spikes caused by theIran warand President Donald Trump’ssweeping tariffs. Inflation is now outpacing wage gains as the war has kept oil and gasoline prices high.

The Biden-era regulation was “unnecessary and costly and actually makes the machinery worse,” Trump said at a ceremony joined by top executives from Kroger, Piggly Wiggly and other grocery chains. The EPA action will protect hundreds of thousands of jobs and save Americans more than $2 billion a year, he said.

The Air-Conditioning, Heating and Refrigeration Institute, which represents more than 330 HVAC manufacturers and commercial refrigeration companies, said the change in approach would “inject uncertainty across the market” and could even raise prices.

“This rule works against basic supply and demand,” said Stephen Yurek, the group’s president and CEO. “By extending the compliance deadline” for phasing out hydrofluorocarbons, or HFCs, the administration “is maintaining and even increasing demand in the market for existing refrigerants while supply continues to fall.”

Manufacturers have already retooled product lines and certified models based on the existing timeline, Yurek said. Nearly 90% of residential and light commercial air conditioning systems use substitute refrigerants, rather than HFCs, he said.

The administration’s action on refrigerants represents a reversal after Trump signed a law in his first term thataimed to reduce harmful, planet-warming pollutants emitted by refrigeratorsand air conditioners. That bipartisan measure brought environmentalists and major business groups into rare alignment on the contentious issue of climate change and won praise across the political spectrum.
