There are many sources of air pollution, including automobiles, power plants, factories, small businesses and household products. Under the Clean Air Act, the EPA develops and enforces rules and regulations for all entities that emit toxic substances into the air. The Agency works with state, local and tribal governments, other federal agencies, businesses and community groups to implement and enforce its regulations. EPA also partners with scientists to study the causes and effects of pollution and to develop environmentally beneficial alternatives to pollution-generating processes.
