Clean Air Act (CAA)

英文Clean Air Act (CAA)

中文 (征集中)


A US federal statute passed in 1963 and amended several times since then, which regulates the type and level of pollutants that can be emitted into the atmosphere. In 1970, the administration and enforcement of the CAA was passed to the newly-created Environmental Protection Agency, and the EPA retains these powers to this day. The CAA limits the amount and type of allowable emissions from devices ranging from large-scale generating facilities to privately-owned automobiles, and covers emissions ranging from carbon dioxide and sulphur dioxide (the primary pollutants produced in coal-fired energy generation) to chlorofluorocarbons (volatile chemicals such as Freon used in cooling systems)
