New requirements by the Environmental Protection Agency will require coal-dependent Indiana to cut its carbon emissions by 20 percent by 2030.
The EPA says that Indiana has three years to come up with a plan to do that.
Gov. Mike Pence said the state "will oppose these regulations using every means available.” Pence said that the Obama Administration is advancing its anti-coal agenda without regard for the impact on the U.S. economy or American workers.
The Indiana Chamber of Commerce called the requirements "potentially devastating" to the state because they could boost electricity costs by as much as 80 percent. Indiana gets 84 percent of its electricity from coal-fired power.
