This bill repeals the EPA's 2024 emissions standards for light- and medium-duty vehicles and amends the Clean Air Act to prevent future regulations from mandating specific technologies or limiting new vehicle availability based on engine type. It directly affects the EPA's regulatory authority and vehicle manufacturers by blocking technology mandates and restrictions on engine types in new vehicles. Key provisions require the EPA to revise regulations within 24 months to align with these changes, ensuring no federal rules limit vehicle choices based on engine technology. The bill's title is misleading, as it does not address automobile retail sales or consumer choice at dealerships.
SJRES 46 is a joint resolution seeking congressional disapproval of an Environmental Protection Agency (EPA) rule concerning California's vehicle emission standards. The rule, submitted in 2023, relates to California's pollution control requirements for motor vehicles, including advanced clean trucks, zero-emission airport shuttles, and heavy-duty engine emissions. This resolution would block the rule from taking effect using a specific federal disapproval process under Title 5 of the U.S. Code. If passed, the rule would have no legal force, meaning California's current standards would remain without the EPA's formal approval for these specific provisions.
Senate Joint Resolution 45 seeks to block an Environmental Protection Agency (EPA) rule that would have allowed California to enforce its Advanced Clean Cars II vehicle emission standards. The resolution uses the congressional disapproval process under federal law to declare the EPA rule invalid, preventing California from implementing its stricter pollution controls for cars and trucks. If passed, this resolution would stop the rule from taking effect, meaning California could not override federal vehicle emission standards with its own requirements. The bill directly affects California's ability to set state-level environmental regulations for motor vehicles and the EPA's regulatory authority.
HJRES 26 is a congressional resolution seeking to block a new Environmental Protection Agency (EPA) rule that set stricter greenhouse gas emission standards for heavy-duty vehicles like trucks and buses. If passed, it would prevent the rule - published in April 2024 - from taking effect, directly affecting vehicle manufacturers required to meet the new standards. The bill uses the Congressional Review Act process to formally disapprove the EPA rule, which would nullify its requirements without altering the underlying regulations.
HRES 354 is a procedural resolution that sets rules for the House to vote on five separate disapproval resolutions (H.J. Res. 60, 78, 87-89). These disapproval resolutions aim to block specific federal agency rules: one from the National Park Service regarding motor vehicles in Glen Canyon, another from Fish & Wildlife on endangered smelt protections, and three from the EPA targeting California's vehicle emissions standards. The resolution streamlines debate and voting on these disapproval measures, waiving most procedural objections to allow direct consideration. If passed, the disapproval resolutions would cancel the agency rules, directly affecting how California implements vehicle pollution controls and wildlife protections. The bill itself does not change policy but enables Congress to block these specific regulations.
This bill (SJRES 55) is a congressional resolution seeking to block a rule issued by the National Highway Traffic Safety Administration (NHTSA). The NHTSA rule, published in January 2025, established safety standards for hydrogen fuel systems in vehicles. The resolution aims to nullify this rule through a formal disapproval process under federal law, meaning the safety standards would not take effect. This directly affects hydrogen vehicle manufacturers and dealers who would have been required to comply with the NHTSA rule.
HJRES 89 is a congressional disapproval resolution that blocks an Environmental Protection Agency (EPA) rule concerning California's vehicle and engine pollution standards. The resolution specifically targets the EPA's "Omnibus Low NOX Regulation" and waiver of preemption, which would have allowed California to enforce stricter emissions rules. By disapproving this rule under Chapter 8 of Title 5 U.S. Code, Congress has nullified the EPA's action, meaning the regulation will have no legal effect. This directly affects the EPA's authority to approve California's state-level pollution control standards for motor vehicles.
H.J.Res. 88 disapproves an Environmental Protection Agency (EPA) rule that would have allowed California to enforce its "Advanced Clean Cars II" vehicle emission standards. This rule, submitted by the EPA on January 6, 2025, sought to grant California a waiver to override federal preemption for its stricter vehicle pollution controls. The resolution, passed by Congress and signed into law on June 12, 2025, formally nullifies the EPA rule, preventing California from implementing its Advanced Clean Cars II program under this specific waiver. The bill directly affects California's ability to set its own vehicle emission standards for passenger cars and light trucks.
H.J. Res. 87 (Public Law 119-15) is a congressional disapproval resolution that prevents an Environmental Protection Agency (EPA) rule from taking effect. The rule, submitted by the EPA on April 6, 2023 (88 Fed. Reg. 20688), related to California’s authority to enforce stricter vehicle emission standards, including for heavy-duty trucks, zero-emission airport shuttles, and advanced clean truck requirements. By disapproving this rule, Congress blocks California from implementing these specific pollution controls under its existing waiver authority. This directly affects California’s ability to regulate motor vehicle emissions independently, as the rule would have allowed the state to enforce its own standards beyond federal requirements.
This bill (SJRES 47) seeks congressional disapproval of an Environmental Protection Agency (EPA) rule that approved California's stricter vehicle pollution standards. Specifically, it targets the EPA's "Omnibus Low NOx Regulation" for motor vehicles and nonroad engines, which California had submitted for federal approval under waiver authority. If passed, the resolution would block this EPA rule from taking effect, preventing California's state-level pollution controls from being implemented under federal oversight.
