WASHINGTON (AP) — Near the end of his first term, President Donald Trump signed into law a bill aimed to reduce harmful, planet-warming pollutants emitted by refrigerators and air conditioners. This bipartisan measure garnered praise from environmentalists and business groups alike.

Five years later, the Trump administration is reversing course by loosening a federal rule that requires grocery stores and air-conditioning companies to reduce powerful greenhouse gases used in cooling equipment.

This shift has disrupted a broad bipartisan consensus on phasing out hydrofluorocarbons (HFCs), which are significantly more potent than carbon dioxide and a major contributor to global warming.

The Environmental Protection Agency (EPA) is now advocating for regulatory policies perceived as less climate-friendly, even if it creates turmoil for the business interests they aim to protect. EPA Administrator Lee Zeldin stated that the new proposal would make American refrigerants affordable, safe, and reliable again.

However, environmentalists counter that this plan will increase climate pollution and jeopardize nations' transition to new refrigerants. They highlight that HFCs are one of the main drivers of heat and pollution, warning that any delay to their phase-out would lead to significant negative outcomes.

Industry groups welcomed the rollback, claiming that the previous compliance timelines were unrealistic and disruptive to their operations. They argue that adjustments had already been made to meet the goals set forth in the original 2020 law.

In response to industry players' concerns, Zeldin clarified that the administration would address complaints from various sectors regarding the federal rules limiting these refrigerants. Advocacy groups emphasize that weakening the EPA regulation creates market confusion and poses potential risks to both innovation and environmental health.
