Earth Policy Institute: The End of an Era — Closing the Door on Building New Coal-fired Power Plants in America : Sustainablog
An April 2007 Supreme Court ruling is proving to be a seminal decision. In Massachusetts v. EPA, the Court ruled that the Clean Air Act gives the agency authority to regulate CO2 emissions and that the EPA must review whether such emissions pose a threat to public health or welfare. Complying with the Court order, new EPA Administrator Lisa Jackson submitted an endangerment finding to the White House in late March 2009 indicating that human health and welfare are indeed threatened by CO2 emissions. This finding opens the door to regulating CO2 emissions under the Clean Air Act. Such regulation would provide a backup option for curbing emissions if Congress fails to set limits on them through legislation.
