Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles-Phase 3".

HJRES 133 is a congressional resolution seeking to block an Environmental Protection Agency (EPA) rule titled "Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles-Phase 3." This rule, published in the Federal Register on April 22, 2024, established new emissions requirements for large trucks and commercial vehicles. The resolution, if passed, would prevent the EPA rule from taking effect by formally disapproving it under standard congressional review procedures. The measure directly affects the EPA’s regulatory authority and vehicle manufacturers who would have been required to comply with the proposed standards.
