Western Caucus Members Join Effort to Repeal California’s Extreme Vehicle Emissions Mandates

Today, the House Energy and Commerce Committee, Congressional Western Caucus Chairman Doug LaMalfa (CA-01), and Western Caucus members introduced three Congressional Review Act (CRA) resolutions to overturn the Biden administration’s approval of California’s vehicle emissions mandates, including the Advanced Clean Cars II regulation, the Advanced Clean Trucks regulation, and the Omnibus Low-NOx Emissions rule.
 
These rules, previously approved by the U.S. Environmental Protection Agency (EPA), allow California to impose aggressive regulations on cars and trucks that drive up costs and restrict consumer choice in California and across the nation. The three CRAs were introduced by Western Caucus Vice Chair Jay Obernolte (CA-23), and Representatives John Joyce (PA-13) and John James (MI-10), to repeal these unrealistic mandates, preventing California from being able to force these costly policies on its residents and onto the rest of the country.
 
“California’s sweeping and unachievable emissions mandates are a direct assault on everyone who lives, works, or does business in our state,” said Chairman LaMalfa. “These regulations drive up costs, limit consumer choice, and force trucking and automotive industries into an impossible transition timeline. Californians are already paying some of the highest fuel and energy costs in the country. These rules are causing the cost of new and used cars and trucks to increase for everyone. If you want to buy an electric vehicle, buy one, but everybody else shouldn’t be forced into this mandate. The Federal Government cannot allow one state to destroy the American car and truck market. Instead of making life even more expensive, we should focus on what consumers want. I’m pleased to support this effort to stop California’s insanity and protect drivers and consumers across my state and the country.”
 
“As a representative of California, I’ve seen firsthand how burdensome regulations from the California Air Resources Board have hurt businesses and hardworking Americans by imposing costly mandates instead of allowing the market to drive innovation,” said Vice Chair Obernolte. “Congress must exercise its oversight authority to ensure these policies do not become the national standard. It is critical we protect jobs, supply chains, and the ability of consumers to choose what is best for them and their families.”
 
“The Newsom Administration’s irrational plan to ban gas-powered cars and trucks is an affront to the freedom of Californians and an economic burden to the whole country,” said Representative Kevin Kiley (CA-03). “The Biden Administration aided and abetted this insanity with special waivers. With the Congressional Review Act resolutions introduced today, we have an opportunity to return to economic reality and restore common sense.”
 
Background
 
Under the Clean Air Act, states are generally prohibited from setting their own tailpipe emission standards for cars and trucks. However, California has a unique exemption under Section 209, which allows the state to establish its own emissions regulations if it submits a waiver to the Environmental Protection Agency (EPA) and receives approval. Once granted, these California standards can also be adopted by other states under Section 177 of the Clean Air Act. Currently, about a dozen states follow California’s emissions policies, effectively turning the state’s regulations into a nationwide mandate.

The Biden administration approved several controversial waivers requested by the California Air Resources Board (CARB), allowing the state to impose extreme emissions rules that impact car and truck costs and availability across the country. These include:

  • Advanced Clean Cars II (ACC2) – Approved in December 2024, this regulation mandates that 35% of new car sales be zero-emission by 2026, increasing to 100% by 2035. At least 12 states have already adopted ACC2. Failure to meet this goal means a maximum penalty of $25,000 per non-compliant vehicle sold to consumers.
  • Advanced Clean Trucks (ACT) – Approved in March 2023, this regulation forces truck manufacturers and retailers to meet strict zero-emission quotas by 2035, including 55% of Class 2B-3 truck sales, 75% of Class 4-8 straight truck sales, and 40% of truck tractor sales. At least 11 states have adopted ACT.
  • Omnibus Low-NOx Emissions Rule – Approved in December 2024, this regulation imposes aggressive emissions reductions on medium- and heavy-duty truck and other engines, requiring NOx emissions to be cut by 75% below current standards for Model Year 2024-2026 compared to 2010 levels and particulate matter emissions to be cut by 50%.
