The D.C. Circuit Court of Appeals has ruled that it’s too early to intercede in a lawsuit challenging the Environmental Protection Agency’s proposed carbon dioxide limits for power plants.

Kentucky is on track to comply with the EPA’s upcoming federal regulations on greenhouse gas emissions—even if no further actions are taken.

It estimates that by 2020, the first year the state will have to meet greenhouse gas limits, Kentucky will have already cut its emissions to 113 percent of the goal.
