EPA: Significant Progress Made in Improving Air Quality

The Environmental Protection Agency (EPA) recently released a report on air quality, showing significant progress by the United States. “Our Nation’s Air: Status and Trends Through 2016” documents steady and significant progress under the Clean Air Act over more than 45 years.

Between 1970 and 2016, the combined emissions of six key pollutants dropped by 73%. In addition, between 1990 and 2016, national concentration averages of the following harmful pollutants decreased significantly:

  • Lead
  • Carbon Monoxide
  • Sulfur Dioxide
  • Nitrogen Dioxide
  • Ground Level Ozone
  • Course Particulate Matter and Fine Particulate Matter

EPA’s Administrator Scott Pruitt said, “Despite the success, there is more work to be done. Nearly forty percent of Americans are still living in areas classified as ‘non-attainment’ for failing to achieve national standards. EPA will continue to work with states, tribes, and local air agencies to help more areas of the country come into compliance.”
