California, your days driving U.S. emissions policy are numbered.
That’s the message behind House Bill H.R. 4117, the Fuel Emissions Freedom Act — and it’s shaking up the automotive world.
Even if it clears Congress, lawsuits are certain. California has never been shy about using the courts to defend its regulatory turf.
First introduced on June 24, 2025, and now under review by the House Committee on Energy and Commerce, the legislation seeks to repeal federal and state motor vehicle emission and fuel economy standards under the Clean Air Act and related laws.
Its stated goals? Lower costs for consumers, simplify compliance for automakers, and revive U.S. competitiveness. But behind the legal jargon lies a direct challenge to one of the most powerful forces in U.S. auto regulation: California.
Game changer
The bill, sponsored by Republican Rep. Roger Williams of Texas and co-sponsored by Republican Reps. Michael Cloud (Texas), Brandon Gill (Texas), and Victoria Spartz (Ind.), takes aim at Section 202 of the Clean Air Act (federal emissions standards) and portions of Title 49 of the U.S. Code (CAFE standards).
But the sharp end of H.R. 4117 is pointed directly at state-level mandates like California’s Advanced Clean Cars II program, which requires 100% zero-emission vehicle sales by 2035. If passed, the bill would prevent California — and any other state following its lead — from setting their own emission or fuel rules, putting Washington and Sacramento directly at odds.
FEFA fix
Supporters argue the current system of EPA rules layered with California’s mandates and CAFE standards create a regulatory maze that raises costs and limits choice.
The Fuel Emissions Freedom Act promises to fix this by:
- Lowering prices for drivers: Meeting the EPA’s 2023 rules, which require a 49% emissions cut by 2032, could raise new car prices by thousands. Repealing these standards would ease costs for buyers and keep more affordable gas-powered vehicles on the market.
- Simplifying regulations: Automakers currently juggle federal requirements and California’s dictates, plus a patchwork of states copying California. The result? Confusion, higher compliance costs, and supply chain strain. H.R. 4117 promises a single, unified system.
- Strengthening U.S. industry: Instead of funneling billions into forced EV development, manufacturers could refocus on consumer demand, job growth, and homegrown production.
- Restoring choice to consumers: With California mandating EV adoption, critics argue consumers are losing the freedom to buy the cars they actually want — trucks, SUVs, or traditional sedans. This bill restores that choice.
Sounds promising, but make no mistake: California is not about to give up its power without a fight.

Waiver goodbye?
Crucial to that power is the state’s unique authority under the Clean Air Act to set its own emission standards, with other states free to follow its lead. For decades, this waiver has allowed California to dictate national auto policy by sheer market size.
H.R. 4117 would revoke that authority, ending California’s role as the de facto regulator for the entire U.S. auto market. Supporters call this a win for fairness and consumer freedom; opponents call it an assault on states’ rights and climate progress.
As of September 2025, the Fuel Emissions Freedom Act sits in committee, facing heavy opposition from Democrats, environmental groups, and California lawmakers. Even if it clears Congress, lawsuits are certain. California has never been shy about using the courts to defend its regulatory turf.
The sheer viciousness of the fight ahead is a testament to how much is at stake: this is about nothing less than who controls America’s automotive future — Washington, Sacramento, or the free market.
