As Americans continue to face high grocery bills, President Donald Trump said Friday he was rolling back environmental rules laid out by the Biden administration on chemicals used in refrigerators and air conditioners, saying this would cut costs.

The restrictions were, in fact, a result of a 2020 bipartisan law Trump signed that year aimed at so-called "super pollutants" because of their effects on climate change, but the president said the new limits had driven up business costs, impacting consumers.

Environmental Protection Agency (EPA) administrator Lee Zeldin said the HFC requirements, finalized in 2023, would be relaxed for grocery stores, AC companies, and semiconductor plants, potentially opening up $2.4 billion in savings.
