A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the National Highway Traffic Safety Administration relating to "Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027 and Beyond and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030 and Beyond".

SJRES 104 is a joint resolution seeking congressional disapproval of a National Highway Traffic Safety Administration (NHTSA) rule that established new fuel efficiency standards for passenger cars (for model years 2027 and beyond) and heavy-duty trucks (for model years 2030 and beyond). The rule, published in the Federal Register on June 24, 2024, would have required automakers to meet stricter emissions targets. If passed, the resolution would block the rule from taking effect, preserving current fuel economy standards. Introduced by multiple senators on July 30, 2024, it follows the congressional review process under Title 5, U.S. Code.
