A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Control of Air Pollution From New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards".

This joint resolution seeks to overturn a 2023 Environmental Protection Agency (EPA) regulation that established stricter emission standards for heavy-duty vehicles, such as semi-trucks and buses. If enacted, the resolution would nullify the rule’s requirements for manufacturers to significantly reduce nitrogen oxide (NOx) and other air pollutants that contribute to soot and smog.
