STATISTICS ON AIR POLLUTION

With the passage of the Clean Air Act in 1970 and later legislation, such as the Clean Air Act Amendments of 1990, total emissions of pollutants such as nitrogen oxide, sulfur dioxide, and carbon monoxide decreased significantly. To learn more about air quality standards and pollution reduction, visit the EPA’s website on air pollutant emissions trends. The data set used to generate the graph below is the Average Annual Emissions for criteria pollutants.
