INDIANAPOLIS (AP) -- Coal-dependent Indiana has to cut carbon emissions by 20 percent by 2030 under new requirements outlined by the U.S. Environmental Protection Agency.
Indiana has three years to come up with a plan to achieve the reductions, which were announced Monday by the EPA.
But some experts say the state government and energy industry have already taken steps toward that goal, such as switching old coal-fired power plants to cleaner natural gas.
Doug Gotham of the Purdue-based State Utility Forecasting Group says moves like that will help Indiana move in the right direction to meet the 2030 goals.
Jodi Perras of the Indiana Sierra Club's Beyond Coal Campaign says most Indiana power plants are aging and need to be replaced.
EPA says Indiana gets 80 percent of its electricity from coal.
