CAr pollution



On April 12, 2023, the U.S. Environmental Protection Agency (EPA) proposed a new plan to reduce harmful tailpipe pollution from passenger cars and light trucks starting with model year 2027. 

The EPA’s current proposal is a good start, but it must be even stronger to curb pollution and improve public health. Within the proposal, the EPA has said it will consider more stringent alternatives. Health professionals must ask the EPA to finalize air pollution safeguards on passenger cars and light trucks that are at least as strong as Alternative 1 in its proposal.  The EPA is accepting comments until July 5.

What can you ask for?

Ask the EPA to finalize air pollution safeguards on cars and light trucks that are at least as strong as Alternative 1 in its proposal.

  • For the U.S. to meet its Paris Climate Agreement goals we need the strongest possible long-term pollution safeguards that will reduce car and light truck greenhouse gas emissions 75% by 2030, putting the country on a path to a 100% zero-emission new vehicle sales target by 2035.

  • According to the EPA’s analysis, the transportation sector accounts for 27% of greenhouse gas emissions and is the fastest-growing emitter of greenhouse gases.


Ask the EPA to move quickly and finalize these new safeguards by the end of the year!  

  • The American Lung Association’s report “Zeroing in on Healthy Air” found that a nationwide transition to zero-emission cars, light trucks, and heavy-duty vehicles –coupled with a transition to zero-emission electricity – would result in:
    o 110,000 premature deaths prevented (nationwide, 2020-2050)
    o $1.2 trillion in health benefits (nationwide, 2020-2050)
    o $1.7 trillion in additional climate benefits (global, 2020-2050)

Ask the EPA to set the strongest possible air pollution safeguards on cars and light truck emissions to protect those most vulnerable, including communities of color.

  • Low-wealth and BIPOC (Black, Indigenous, People of Color) communities experience disproportionate harm from dirty vehicle pollution, leading to increased rates of asthma and other respiratory illnesses. 

  • Low-wealth and BIPOC communities are often closest to highways and bear the greatest burden from vehicle pollution.

What types of pollution do cars and light trucks emit?

What are the health effects of exposure to pollution from car and light truck emissions?

  • Exposure to air pollution can lead to health problems, including increased risk of asthma attacks, strokes, heart attacks, cancer and premature deaths. 

How is climate change related to pollution from cars and light trucks?

Will enacting strong pollution limits on car and light truck emissions hurt the economy, auto workers, or manufacturers?​​
