The centerpiece of President Obama's battle against climate change is the proposed Clean Power Plan.

Under the plan, states would set goals to reduce carbon dioxide emissions by the year 2030. The states could cut emissions in a variety of ways and it would be up to the states to decide.

Pennsylvania's target was to reduce emissions by more than 30%.

The plan was controversial because many believe it will have a negative economic impact, especially on certain industries like coal.

Lost in the vast media coverage of the New Hampshire primary three weeks ago, the U.S. Supreme Court issued a stay against implementing the Clean Power Plan. Pennsylvania was not one of the states that challenged the Environmental Protection Agency's authority to regulate emissions. In fact, the Wolf Administration may go ahead and slash emissions.

We'll hear what the Administration plans are on Wednesday's Smart Talk when we're joined by John Quigley, Pennsylvania's Secretary of the Department of Environmental Protection .
