President Trump late Friday afternoon signed four pieces of legislation that overturn Biden-era efficiency rules.

Three of the Biden-era regulations overturned by Trump had sought to improve efficiency for household water heaters, walk in freezers and commercial refrigerators and freezers. Trump also overturned a Biden rule related to labeling requirements for consumer products.

A tool called the Congressional Review Act (CRA) allows Congress, with the president’s approval, to undo recently-passed regulations. The CRA is most commonly used at the start of a new administration to undo regulations issued at the end of the last administration.
