HARRISBURG, Pa. (AP) — Pennsylvania’s Supreme Court will take its first crack at whether a governor can force power plant owners to pay for their planet-warming greenhouse gas emissions, or whether he first needed approval from a Legislature that opposed the plan. Hanging in the balance is Pennsylvania’s effort to become the first major fossil fuel-producing state to adopt carbon pricing. On Wednesday, the state’s highest court will hear arguments on whether a lower court was right to halt Pennsylvania’s participation in a multistate consortium that imposes a price and declining cap on carbon dioxide emissions from power plants. The way the justices react could give hints as to how they might ultimately rule.
