President Trump on Thursday announced the rollback of rules to limit the use of high-polluting refrigerants by grocery stores and air conditioning companies.

“This was a tremendous burden, a tremendous cost,” said Trump, surrounded by executives from supermarket chains including Kroger, Fairway, Neimann Foods and Piggly Wiggly. “It was making the equipment unaffordable, and the actual benefit was nothing.”

The move loosens rules meant to restrict hydroflourocarbons, a class of climate-damaging chemicals used in cooling equipment. HFCs are known as “super pollutants” because their impacts on climate change can be hundreds of thousands of times greater than carbon dioxide during their shorter lifespans.

In the move Thursday, the Environmental Protection Agency extends the deadline for companies to comply with a 2023 rule transitioning refrigerators and air conditioners off HFCs and onto new cooling technologies. Reducing these chemicals and moving to cleaner refrigerants has long been a bipartisan issue and Trump himself signed the bipartisan law that led to the rule during his first term in office.

Trump is also proposing exemptions from a rule requiring leak repairs on large-scale refrigeration systems.

The administration framed the changes as part of their effort to bring down high grocery costs. EPA administrator Lee Zeldin said the actions will save $2.4 billion for Americans and safeguard 350,000 jobs.

“Americans who wanted to be able to fix their equipment were instead being required to buy far more costly new equipment and that just doesn’t make any sense,” said Zeldin.

Trump dismissed the climate concerns, saying his changes “are not going to have any impact on the environment.”

He said he wants to get rid of the technology transition rule entirely in the future.
