Tell EPA: Support States’ Authority for Cleaner Cars

Cleaning up vehicle emissions is essential to addressing climate change and keeping our families healthy. Gasoline-powered cars contribute to air pollution and drive climate change, which poses a major threat to lung health. Transitioning to cleaner engines and zero-emission vehicles will help curb climate change and improve public health at the same time.

Thankfully, the U.S. Environmental Protection Agency has proposed to restore states’ authority to implement more protective vehicle standards, which is important for reducing vehicle emissions nationwide.

Join the American Lung Association and call on the U.S. Environmental Protection Agency to finalize this key step toward cleaner cars.

Dear Administrator Regan:

We write to urge the U.S. Environmental Protection Agency to immediately restore California's Clean Air Act authority to enact more health-protective standards for passenger vehicles and light trucks, and other states’ ability to follow those stricter standards.

Currently, the transportation sector is the United States’ largest source of carbon pollution. Carbon pollution contributes to climate change, which degrades air quality and makes extreme weather events, such as flooding, drought, heatwaves and wildfires, more intense and frequent. Health consequences of unhealthy air include shortness of breath, wheezing, coughing and pulmonary inflammation, which pose serious threats to all Americans, especially children, older adults, low-income communities, communities of color and people living with chronic diseases.

In order to avoid the worst health impacts of climate change, the nation must take strong, immediate action to reduce pollution. Lowering transportation emissions is a key component of that action. The ability for states to set stronger standards under the Clean Air Act to protect their residents from pollution is a tool that has played an important role in reducing harmful emissions nationwide.

We urge EPA to quickly restore states’ authority to enact more protective motor vehicle pollution standards. Beyond restoring California’s waiver for greenhouse gases and zero emission vehicle standards, we also call on the agency to work quickly to set strong, ambitious greenhouse gas and criteria pollutant standards for cars, light trucks and SUVs and accelerate the full transition to zero-emission vehicles.

Sincerely,

If you take action and have not already registered, you will receive periodic updates and communications from American Lung Association.
