Pennsylvania's fossil fuel power plants began having to comply with Gov. Tom Wolf's hallmark climate rule on Friday, one day after a U.S. Supreme Court decision restricted federal regulators' tools for cutting greenhouse gas pollution across the power sector nationwide.
Pennsylvania's coal and natural gas-fired power plants will pay for each ton of carbon dioxide they release as of July 1 as a Wolf administration rule to rein in climate warming pollution from power plants started tracking and capping emissions.
The U.S. Supreme Court's ruling shifted attention to state and local climate action, which is unaffected by the high court decision because it is authorized under state laws and constitutions.
