13–16 minutes to read
Each year since the implementation of the Clean Air Act in 1970, the EPA releases its Annual Air Report, highlighting the nation’s progress in the mission of reducing levels of hazardous pollutants in the air.
In this article, air quality experts from global air filtration industry leader Camfil explain the findings of the EPA’s Annual Air Report and what it means for Americans.
United States Air Pollution Follows a Downward Trend
The data from the Annual Air Report shows that key pollutants have been declining, both overall since the introduction of the Clean Air Act and year-over-year. It’s important to note that at the same time these key pollutants have declined, the US economy has grown and overall energy usage has increased. This demonstrates actions taken to provide clean and healthy air do not hamper economic growth.
Since 1990, the EPA has observed the following decreases in various pollutants:
- Carbon Monoxide (CO) 8-Hour, 79%
- Nitrogen Dioxide (NO2) Annual, 61%
- Nitrogen Dioxide (NO2) 1-Hour, 54%
- Ozone (O3) 8-Hour, 21%
- Particulate Matter 10 microns (PM10) 24-Hour, 32%
- Particulate Matter 2.5 microns (PM2.5) Annual, 37% (from 2000)
- Particulate Matter 2.5 microns (PM2.5) 24-Hour, 33% (from 2000)
- Sulfur Dioxide (SO2) 1-Hour, 91%
Though total emissions of key pollutants have dropped by 78% since the very first Annual Air Report, the presence of dangerous air pollutants has not been completely eliminated, which still has notable effects on human...
