Washington D.C. – On May 22, 2026, President Donald Trump, alongside Environmental Protection Agency (EPA) Administrator Lee Zeldin, announced a significant rollback of Biden-era regulations designed to phase out hydrofluorocarbons (HFCs), potent greenhouse gases widely used as refrigerants in commercial settings, including grocery stores. The administration asserted that this move would alleviate a "tremendous burden" on retailers, directly translate to lower grocery prices for American consumers, and save families an estimated $2.4 billion, with $800 million specifically impacting supermarkets. However, this claim immediately met with skepticism from environmental organizations, economists, and climate policy experts, who argue that the impact on food prices will be negligible while the environmental costs could be substantial, jeopardizing crucial climate targets.
The Policy Shift: Loosening the Reins on HFCs
The regulations, initially implemented by the Biden administration in 2023, were part of a broader effort to reduce HFC emissions under the framework of the American Innovation and Manufacturing (AIM) Act of 2020. This bipartisan legislation, notably signed into law by then-President Trump, mandated a phasedown of HFC production and consumption in the United States by 85% over 15 years, aligning the nation with international climate objectives. The Biden-era rules established specific technology transition programs, setting deadlines for sectors like retail food refrigeration to shift from high-GWP (Global Warming Potential) HFCs to lower-GWP alternatives for new equipment installations. These rules did not mandate the replacement of existing HFC-based systems, focusing instead on future installations to encourage innovation and a gradual industry transition.
During a White House press conference that featured prominent grocery industry executives, including the CEOs of Kroger and Fairway, President Trump framed the rollback as a decisive action against what he termed "ridiculous regulations" that had unfairly inflated operational costs for businesses and subsequently consumer prices. "Thanks to today’s reforms," President Trump declared, "the American people have lower grocery prices, cheaper transportation of goods, and lower cost of air conditioning at no detriment at all to our country, including environmental detriment." EPA Administrator Zeldin echoed this sentiment, emphasizing the projected financial relief for American households. The EPA’s official statement claimed the changes were necessary to provide "flexibility and affordability" for businesses, particularly small enterprises, and to ensure compliance with the AIM Act’s overall phasedown goals while minimizing economic disruption.
The Science and Policy of HFCs: A Background
To understand the implications of this policy reversal, it’s crucial to grasp the nature of HFCs and their regulatory history. Hydrofluorocarbons are synthetic organic compounds that became prevalent in the 1990s as replacements for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). CFCs and HCFCs were phased out globally under the Montreal Protocol on Substances that Deplete the Ozone Layer, an international treaty ratified in 1987, due to their severe damage to Earth’s protective ozone layer. While HFCs do not deplete the ozone layer, they are exceptionally potent greenhouse gases, often hundreds to thousands of times more effective at trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period. For instance, HFC-134a, a common refrigerant, has a GWP of 1,430, meaning one ton of HFC-134a released into the atmosphere has the same warming effect as 1,430 tons of CO2. Other HFCs can have GWPs even higher, reaching into the tens of thousands.
Recognizing their significant contribution to climate change, the international community moved to address HFCs through the Kigali Amendment to the Montreal Protocol, adopted in 2016. The Kigali Amendment committed signatory nations to an 85% phasedown of HFC production and consumption by 2047. While the United States signed the Kigali Amendment, its ratification had faced political hurdles, though the AIM Act of 2020 effectively implemented the amendment’s goals domestically. The AIM Act directed the EPA to establish regulations for the phasedown, including allocations for HFC production and consumption, as well as sector-specific technology transition rules aimed at encouraging the adoption of lower-GWP alternatives such as natural refrigerants (e.g., CO2, ammonia, propane) and new synthetic blends.
The Biden-era rules targeted sectors like supermarkets, where large refrigeration systems can contain hundreds or even thousands of pounds of HFCs, and leaks contribute significantly to emissions. The regulations were designed to spur innovation and investment in more climate-friendly technologies, which many industry leaders had already begun adopting due to increasing awareness of environmental impact, rising HFC costs, and long-term regulatory certainty. The phasedown schedules were carefully calibrated to allow industry time to adapt and innovate, with technology transition deadlines for new equipment installations beginning in 2025 for specific sub-sectors within retail food refrigeration.
Economic Realities Versus Political Rhetoric
The administration’s central argument for the rollback rests on the premise that HFC regulations impose an undue economic burden on grocers, thereby driving up food prices. However, this assertion has been widely challenged by independent economic analyses. Economists point out that the cost of refrigeration equipment and refrigerants represents a relatively minor component of a grocery store’s overall operating expenses, typically a fraction of a percent of total revenue. Energy costs, while significant, are usually in the low single digits percentage-wise, and the incremental cost of transitioning to HFC-free refrigeration for new equipment is even smaller. For a typical supermarket, the entire energy bill, including refrigeration, lighting, and HVAC, rarely exceeds 2% of total sales. The specific costs associated with HFC refrigerants or the transition to alternatives are a fraction of this already small percentage.
David Doniger, a senior strategist for climate at the Natural Resources Defense Council (NRDC), vehemently criticized the administration’s rationale. In a public statement, Doniger highlighted that "thousands of grocery stores have already made the transition" to climate-friendly refrigerants, demonstrating the feasibility and, often, the long-term economic benefits of such investments. He emphasized that "the affordability crisis is very real and deserves real solutions, rather than thinly veiled environmental rollbacks that leave the United States stuck with outdated technologies of the past." Many early adopters of HFC alternatives, particularly large chains and sustainability-focused businesses, have reported long-term operational savings due to greater energy efficiency, reduced refrigerant leak rates, and insulation from volatile HFC prices. The global market for HFCs has seen price increases due to the international phasedown, making alternatives economically competitive, if not superior, in the long run.
Furthermore, the original Biden-era regulations specifically applied only to new refrigeration equipment, meaning grocers were not compelled to replace their existing HFC systems prematurely. This distinction is crucial, as it allowed for a natural depreciation cycle and avoided immediate, costly overhauls. The argument that these regulations were a primary driver of rising grocery prices, which have been influenced by a complex interplay of supply chain disruptions, labor shortages, energy costs, and geopolitical events, finds little support among most economists. The $2.4 billion in savings cited by the administration, while substantial in absolute terms, would likely translate to a negligible per-household saving when distributed across the entire American population, especially considering the already low proportion of refrigeration costs in the overall food supply chain.
During the press conference, when asked how the administration would ensure grocers pass any purported savings on to consumers, President Trump deferred the question to Kroger CEO Greg Foran. Foran responded, "We’re actually right in the middle of doing that at the moment. We certainly are interested in ensuring that all our customers across the country are paying the right price." This statement, however, appears to align more with Kroger’s broader business strategy than a direct response to HFC savings. In an earlier interview with Bloomberg, Foran had indicated Kroger’s plans to slash prices to remain competitive with discount retailers like Walmart and Costco, suggesting that market competition, rather than regulatory relief, is the primary driver for price adjustments. This distinction casts further doubt on the administration’s claim that HFC rule changes would be the catalyst for lower consumer prices.
Environmental Repercussions: A Setback for Climate Action
The environmental implications of loosening HFC regulations are a significant concern for climate scientists and environmental advocates. The NRDC had previously estimated that the Biden-era regulations, if fully implemented, had the potential to eliminate greenhouse gas emissions equivalent to that of 10 coal-fired power plants by 2050. This translates to billions of metric tons of CO2 equivalent emissions avoided over the coming decades, a crucial contribution to the nation’s and the world’s efforts to keep global temperatures within a safe range, as outlined by the Paris Agreement goals. Without these regulations, the projected emissions reductions are now at risk, potentially slowing the progress towards national climate targets.
HFCs, often referred to as "super pollutants" due to their exceptionally high global warming potential, contribute substantially to the warming effect of the atmosphere even in small quantities. By rolling back the phasedown requirements for new equipment, the EPA’s decision could effectively prolong the reliance on these climate-damaging refrigerants, leading to increased emissions over time. Environmental groups, including the Sierra Club, the Environmental Defense Fund (EDF), and the League of Conservation Voters, swiftly condemned the move, labeling it a regressive step that prioritizes short-term political narratives over long-term environmental sustainability and public health. They argue that delaying the transition to safer alternatives not only exacerbates climate change but also undermines the investment already made by forward-thinking companies in green technologies and dampens innovation in the refrigeration sector.
The decision also raises questions about the United States’ commitment to global climate leadership. While the AIM Act demonstrated a domestic commitment to HFC reduction, aligning with the spirit of the Kigali Amendment, this rollback could send mixed signals to the international community regarding the nation’s resolve to address climate change comprehensively. It risks positioning the U.S. as an outlier when many other developed nations are accelerating their transitions away from high-GWP refrigerants, potentially impacting diplomatic efforts on broader climate issues.
A Pattern of Regulatory Reversals
This rollback is not an isolated incident but rather fits into a broader pattern of regulatory reversals observed in recent years. Last year, in 2025, Republicans in Congress also rolled back Biden-era energy efficiency standards for commercial refrigerators used across the food supply chain – by food processors, distributors, grocery stores, food banks, and restaurants. These standards were designed to reduce energy consumption, lower utility bills, and decrease greenhouse gas emissions associated with electricity generation. Taken together, these actions indicate a consistent administrative strategy to dismantle environmental regulations, often under the guise of reducing economic burdens and promoting business flexibility. Critics contend that such actions often ignore the long-term societal costs associated with increased pollution and climate change.
While the EPA’s official announcement stated that the changes were intended to "maintain compliance" with the AIM Act, President Trump’s public statements during the press conference suggested a more fundamental opposition to the underlying legislation. He indicated a desire to "permanently throw out the regulations," stating, "The big thing now is we’re going to get rid of the law that was signed quite a while ago." This potentially signals a future legislative effort to repeal the AIM Act itself, which would represent an even more drastic departure from the current policy trajectory and the bipartisan consensus that led to its enactment in 2020. Such a move would not only reverse the HFC phasedown but also dismantle the legal framework for managing these powerful greenhouse gases, potentially leading to a resurgence in their use and emissions.
Looking Ahead: The Future of Refrigeration and Climate Policy
The loosening of HFC regulations sets the stage for continued debate and potential legal challenges. Environmental organizations are likely to explore legal avenues to contest the EPA’s decision, arguing against its scientific basis and potential conflict with the broader mandate of the AIM Act. The decision also creates uncertainty for businesses that have already invested in or were planning to transition to lower-GWP refrigerants. While some may welcome the temporary reprieve from compliance deadlines, others might view it as a disruption to long-term planning and an erosion of regulatory predictability. Companies that have already invested heavily in new, compliant technologies might also face a competitive disadvantage if their competitors are now allowed to delay similar investments.
The long-term implications extend beyond the immediate economic and environmental impacts. It touches upon the fundamental question of how regulatory policy balances economic concerns, particularly during periods of inflation, with critical environmental imperatives. The administration’s focus on immediate cost savings, even if unsubstantiated by broad economic analyses, resonates with a segment of the public grappling with rising living costs. However, critics warn that such short-sighted policies ignore the escalating costs of climate change, including increased extreme weather events, agricultural disruptions, infrastructure damage, and public health impacts, which ultimately impose far greater burdens on society than the costs of transitioning to cleaner technologies.
The trajectory of HFC phasedown in the United States, once seen as a bipartisan success story aligning economic innovation with environmental protection, now faces a period of renewed uncertainty. The May 22, 2026, announcement marks a pivotal moment, challenging the consensus on climate action and reigniting a familiar ideological battle over the scope and necessity of environmental regulation. The true costs and benefits of this decision, both for consumers’ wallets and the planet’s health, will undoubtedly be a subject of intense scrutiny in the years to come, as the nation grapples with the intertwined challenges of economic stability and environmental stewardship.
