Clean Air Markets

EPA’s Clean Air Markets Division (CAMD) runs programs that reduce air pollution from power plants to address several environmental problems, including acid rain, ozone and particle pollution, and interstate transport of air pollution. CAMD programs include the Acid Rain Program (ARP), the Cross-State Air Pollution Rule (CSAPR), and the CSAPR Update.
