Fossil-fueled vehicles account for the largest share of greenhouse gas emissions in the United States and are a top source of air pollution across the West. The new Advanced Clean Cars II (ACC II) standard is a policy that states can begin adopting this year to accelerate the economic, environmental, and health benefits of electric vehicles (EVs).
Transportation electrification is a key strategy in the fight to avoid the worst impacts of climate change and improve air quality across the West. ACC II will make new EVs more reliable and affordable, so that they can meet the needs of all drivers.
As the power sector in the Interior West continues to reduce its fossil-fuel use, we can use that clean electricity to power electric vehicles, resulting in even greater reductions in the harmful fossil-fuel emissions that cause climate change, pollute our air, and harm communities’ health. Even with our current electricity generation mix, EVs emit two to five times less greenhouse gas pollution than gasoline powered vehicles. The ACC II standard will help Western states rapidly achieve the benefits of EVs.
