Information About

Clean Air Act




A Clean Air Act describes one of a number of pieces of legislation relating to the reduction of Smog and Air Pollution in general. The use of governments to enforce clean air standards has contributed to an improvement in human health and longer life spans. Critics argue it has also sapped corporate profits and contributed to Outsourcing , while defenders counter that improved environmental Air Quality has generated more jobs than it has eliminated.

Additionally, air quality legislation has led to widespread use of Atmospheric Dispersion Model s, including Point Source models, Roadway Air Dispersion Model s and aircraft air pollution models in order to analyze air quality impacts of proposed major actions.

United States


The United States Congress passed the Clean Air Act in 1963, the Air Quality Act in 1967, the Clean Air Act Extension Of 1970 , and Clean Air Act Amendments in 1977 and 1990. Numerous state and local governments have enacted similar legislation, either implementing federal programs or filling in locally important gaps in federal programs.

The Clean Air Act (1990) proposed Emissions Trading , added provisions for addressing Acid Rain , Ozone Depletion and toxic air pollution, and established a national permits program.

The Clean Air Act (2005) , a United States Environmental Law , introduced further regulation.

President Bush issued an by a Supreme Court ruling that the EPA must take action under the Clean Air Act to regulate GHG emissions from motor vehicles. President proposed the 20-in-10 Bill , a goal of reduce gasoline by 20 percent over the next ten years.

He sent to Congress a proposal that would meet it in two steps:
  • First, set a mandatory fuel standard that requires 35 billion gallons of renewable and other alternative fuels by 2017. That's nearly five times the 2012 current target. In 2017, this will displace 15 percent of projected annual gasoline use.


  • Second, the proposal of continuing the efforts to increase fuel efficiency: reforming and modernizing Corporate Average Fuel Economy (CAFE) Standards for cars and extending the current Light Truck Rule . In 2017, this will reduce projected annual gasoline use by up to 8.5 billion gallons, a further 5 percent reduction that, in combination with increasing the supply of renewable and other alternative fuels, will bring the total reduction in projected annual gasoline use to 20 percent. http://www.whitehouse.gov/news/releases/2007/05/20070514-2.html
