Colorado has joined a growing list of states that will sue the Environmental Protection Agency in an attempt to stop the implementation of President Obama's controversial Clean Power Plan.
Attorney General Cynthia Coffman said the lawsuit, challenging the EPA's authority, represents "crucial litigation" against the measure first proposed last year. More than 20 states are expected to be a part of the filing.
"We have been looking at (the plan) and evaluating whether or not there is such an impact on Colorado that we needed to put our name on a lawsuit ," Coffman, a Republican, said in an interview Friday with The Denver Post. "... We just determined this week that is exactly where we need to be."
The Clean Power Plan targets existing coal-burning power plants to cut carbon emissions nationwide by 32 percent before 2030 against 2005 levels. Obama touted the initiative as the nation's most important step to address climate change.
