Advanced Clean Cars, also known as Clean Cars Standards, is a set of standards designed to put more zero-emission vehicles on the road and improve air quality. These standards are created by the California Air Resources Board (CARB), but have since also been adopted by 17 other states, including Nevada, Oregon, Virginia and, most recently, New Mexico. The standards require automakers to increasingly sell more EVs each year. Under the Clean Air Act, California has the special authority to set state clean car standards that go above and beyond federal standards to cut tailpipe pollution. Other states can and have adopted these standards, making it the best tool states have to address their own unique air quality problems.
The standards currently in effect, Advanced Clean Cars I, are set to expire in 2025 and CARB is in the process of establishing the next set of standards for 2026 and beyond. This next set of standards, Advanced Clean Cars II, comes at a crucial moment to boost the electric vehicle industry and address climate change. Once CARB establishes Advanced Clean Cars II, other states will be able to adopt the updated regulations and drive EV uptake across the country.
Transportation is the largest source of emissions in many states and the U.S. as a whole and the standards set by the California Air Resources Board are one of the most important tools to put more electric vehicles on the road. These standards are a huge opportunity to transition to electric vehicles, reduce emissions, improve air quality, and slow climate change. With strong Advanced Clean Cars II standards, states across the country can go all-electric, bringing many significant benefits to each state.
