Take Action

Tell President Obama and the US DOT to stop oil trains carrying diluted tar sands and fracked shale oil from the Bakken formation—both are more toxic, more explosive, and more carbon-intensive than conventional crude.

Air Quality

Global warming and air pollution are related problems linked by the combustion of fossil fuels. The burning of coal, oil, and natural gas produces not only greenhouse gases, but also a range of harmful air pollutants, including ozone, airborne particulates, sulfur dioxide, and nitrogen oxides. Exposure to these pollutants causes a number of adverse health effects ranging from shortness of breath and coughing to lung cancer and premature death. As emissions of greenhouse gases continue to rise, so too will emissions of these harmful air pollutants. Increasing temperatures will further worsen air quality problems across the United States. Hotter temperatures will speed the formation of ground-level ozone, the main component of smog. Smog exposure damages the lungs and can lead to the development and aggravation of chronic lung diseases, such as asthma. Higher temperatures, combined with elevated carbon dioxide levels, may also increase the concentration of natural air pollutants, such as pollen, which will exacerbate the symptoms of people with allergies. Additionally, as people struggle to adapt to warmer temperatures, increased energy use to power air conditioners on hot days would put even greater amounts of pollutants into the air.

Action Alerts

  • Tell President Obama: Ban Oil Trains

    Tell President Obama and the US DOT to stop oil trains carrying diluted tar sands and fracked shale oil from the Bakken formation—both are more toxic, more explosive, and more carbon-intensive than conventional crude.

  • Tell EPA: Public Health needs a strong Haze Rule

    The EPA must improve the Regional Haze Rule so polluters are held accountable and everyone can experience healthy air at our national parks and wilderness areas.

    What now, after the Supreme Court stay?
    The Supreme Court in February 2016 issued a "stay," or a temporary suspension, of the Clean Power Plan while a lower court reviews this legal challenge. This situation raises many questions.
