People across America regularly breathe unhealthy air that increases their risk of premature death, asthma attacks and other adverse health impacts.
In 2016, 73 million Americans experienced more than 100 days of degraded air quality with the potential to harm human health. That is equal to more than three months of the year in which smog and/or particulate pollution was above the level that the EPA has determined presents “little to no risk.” Millions more people in urban and rural areas experienced less frequent but still damaging levels of air pollution.
To safeguard public health, the nation needs to preserve and strengthen existing air quality protections at the federal and state level and move to reduce the future air pollution threats posed by global warming.
As the Trump administration considers weakening federal air quality and global warming emissions standards, air pollution remains a threat to public health. According to a new report by Environment Arizona Research & Policy Center, 4.6 million people in the Phoenix metropolitan area experienced 110 days of degraded air quality in 2016, increasing the risk of premature death, asthma attacks and other adverse health impacts.
