Air pollution has long been recognized as a problem in the United States. The passage of the Clean Air Act (CAA) in 1963 provided federal support for efforts to reverse and control air pollution. In 1970, Congress passed the Clean Air Act Extension, amending the CAA to provide for strict national ambient air quality standards (NAAQSs) and their enforcement. The 1970 and later amendments have sought to reduce atmospheric ozone, carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), hydrocarbons, lead, and particulate matter. The 1990 amendments also set provisions for toxic air pollutants. The legislation has been primarily aimed at protecting human health and preventing or reducing acid rain, rather than mitigating climate change.
