Trump Eases HFC Rules, EPA Says It Will Lower Costs

President Donald Trump is moving to loosen limits on some of the most potent climate pollutants on the market, betting that cheaper cooling today will matter more to voters than hotter temperatures tomorrow. On Thursday, Trump announced that his administration will roll back parts of Biden-era restrictions on hydrofluorocarbons, or HFCs, the powerful refrigerant chemicals often dubbed “super pollutants.” The move, rolled out publicly by EPA Administrator Lee Zeldin, was pitched as a way to cut costs for businesses and consumers, especially grocery chains that rely on sprawling refrigeration systems. Environmental advocates quickly warned that the shift could slow the industry’s transition to cleaner coolants and bump up near-term climate emissions.

What the White House Announced

According to The New York Times, the administration plans to delay and relax sector-specific restrictions on HFCs that apply to supermarkets, commercial refrigeration, air-conditioning systems and semiconductor facilities. In practical terms, that means companies would have more time to swap out high‑polluting coolants and more options for what they can legally use in the meantime.

The Associated Press reported that Zeldin framed the change as a major cost saver, saying it would “allow businesses to choose the refrigeration systems that work best for them, saving them billions of dollars.” Executives from big-name grocery chains, including Kroger and Piggly Wiggly, were expected at a White House event to underscore the message that relaxing the rules would ease the financial squeeze on food retailers and, eventually, shoppers.

Officials say the rule rewrite will expand the types of refrigerants companies can use and push back several compliance deadlines that had been set under the previous approach.

How It Rewrites the AIM Act Rollout

Congress’ 2020 American Innovation and Manufacturing (AIM) Act instructed the Environmental Protection Agency to phase down HFC production and consumption by roughly 85 percent and to manage sector-by-sector technology shifts. As explained in the EPA background materials, the goal was to curb high global-warming-potential refrigerants and speed the move to lower-polluting alternatives.

The California Attorney General's Office has argued that the Trump administration’s proposal, which would raise allowable global-warming-potential thresholds for certain equipment and relax deadlines, “would significantly undermine” the AIM Act’s objectives by slowing the planned phase-down.

Industry Backing and Political Rationale

The White House is selling the shift as an affordability play at a time when voters are worn out by high prices, from gas pumps to grocery aisles. As the Associated Press noted, administration officials argue that easing refrigerant restrictions will help grocers avoid steep equipment upgrade costs and supply bottlenecks, which they say could ultimately keep food prices from climbing even higher.

Some trade groups and grocery executives have welcomed the added flexibility, casting the prior timelines as aggressive enough to risk equipment shortages and surprise compliance bills. The political subtext is hard to miss: Trump’s team is looking for concrete examples it can point to when it claims to be cutting red tape and lowering costs ahead of this year’s elections.

Critics and Legal Stakes

Environmental organizations and a multistate coalition of attorneys general see it very differently. They argue the rule change would undercut years of bipartisan work to rein in a powerful, short-lived climate pollutant that heats the planet far more intensely than carbon dioxide, even if for a shorter period.

In November 2025, the California Attorney General and CARB led 17 attorneys general and the City of New York in filing a comment letter blasting similar reconsiderations. The letter warned that raising allowable global-warming-potential levels and delaying the phase-down timetable would increase emissions and weaken the federal program.

Federal notice and rule pages tracked in the Federal Register, along with reporting in trade outlets, indicate the rule has already gone through notice-and-comment and federal review. If the administration finalizes it, legal challenges from states and advocacy groups are widely expected.

How the courts respond will determine whether refrigeration and air-conditioning suppliers actually shift back toward higher-GWP fluids, or whether judges and state-level rules effectively keep the original AIM Act trajectory in place. For now, the refrigerant rule fight is shaping up as a high-stakes test of the Trump administration’s broader effort to remake climate and pollution policy while hoping voters feel some relief in their wallets.
