Advanced Clean Cars II

​​​​​​​This program accelerates the transition to zero emission cars, trucks, and SUVs.

What is Advanced Clean Cars II?

The Advanced Clean Cars II (ACC II) program is a state-level regulation designed to accelerate the transition of light-duty passenger cars, trucks, and SUVs to zero emission models.

Adopted by California in 2022, ACC II builds on the Advanced Clean Cars I standards by modifying the Low-Emission Vehicle Program and Zero Emission Vehicle Program. Specifically, ACC II makes the following changes:

  • Low-Emission Vehicle Program: Sets increasingly stringent emissions standards for gasoline-powered vehicles to reduce emissions.
  • Zero Emission Vehicle Program: Directs manufacturers to sell a growing percentage of zero-emission vehicles, requiring 100% of new vehicle sales to be zero-emission by 2035. ACC II does not regulate the sale of used vehicles.

The percentage of new vehicle sales that are required to be zero-emission under ACC II increases at the following levels:

Since its adoption in California, 12 other states and the District of Columbia have adopted or announced plans to consider adopting the ACC II program.

Why should my state adopt ACC II?

Transitioning to zero emission light-duty passenger cars, trucks, and SUVs would provide significant economic, safety, public health, and environmental benefits to our communities. The ACC II program is accelerating this transition.

For drivers, owning an EV can save them between $6,000-$12,000 over the lifetime of their vehicle. This is because EVs cost 60% less to power and half as much to repair and maintain. EVs also provide significant safety features, such as a lower center of gravity that improves handling and reduces the risk of a rollover.

Of course, the benefits of driving an EV go beyond the owner of the vehicle. Removing tailpipe emissions from our communities will result in significant public health benefits, particularly for front-line communities that live near major transportation corridors.The American Lung Association estimates that achieving 100% zero-emission vehicle passenger vehicles sales by 2035 would contribute to $978 billion in public health benefits, including 89,300 fewer premature deaths, 2.2 million fewer asthma attacks, and 10.7 million fewer lost workdays.

Transitioning to EVs would also significantly reduce greenhouse gas emissions. Transportation is currently the largest carbon-emitting sector in the United States, accounting for nearly one-third of total carbon emissions. EVs release significantly fewer emissions per mile over the lifetime of the vehicle no matter the source of the energy used to charge the vehicle. As energy production moves to renewable energy sources, those emissions will continue to decrease.

Are the ACC II goals achievable?

Yes! The automotive industry has aligned behind electrification as the most commercially viable way to decarbonize the transportation sector, with companies prioritizing investment in the EV supply chain to meet these goals and more than 40 vehicle models available for purchase.

Federal and state-level programs are also encouraging manufacturing of EVs in the United States and lowering costs for drivers. Incentives found in the Inflation Reduction Act (IRA) are encouraging manufacturers to invest in domestic production, resulting in more than $164 billion in private investments as of March 2024. The IRA also includes the New Clean Vehicle Credit that provides up to $7,500 to help lower the cost of a new EV for purchasers of qualifying zero-emission vehicles—which can be claimed at the point-of-sale.

Many states also provide similar incentives to support the purchase of EVs, and there are credits to support the purchase of used EVs.

Meanwhile, EV charging infrastructure continues to grow, spurred on by public and private investment. In December 2023, the first public EV charging station funded by the National Electric Vehicle Infrastructure (NEVI) program from the Bipartisan Infrastructure Law went into operation in Ohio. The NEVI program aims to support the installation of public charging stations within every 50 miles along our nation’s highway system. This effort is also supporting investment in American manufacturing of EV charging products.
