Colorado has joined a growing list of states that will sue the Environmental Protection Agency to stop the implementation of President Barack 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.
In Colorado, the plan calls for a 28 percent reduction in overall carbon dioxide emissions by 2030 against 2012 levels.
Federal officials contend the plan, formally announced by Obama at the beginning of the month, can help leverage the international adoption of similar rules. Detractors have called the initiative a "war on coal" with crippling economic impacts.
