On February 9, 2016, the U.S. Supreme Court issued a 5-4 decision staying implementation of the Clean Power Plan until the D.C. Circuit rules on challenges to the Plan. The Court left open the possibility that it would review the D.C. Circuit’s ultimate decision.
The decision delays President Obama’s Climate Action Plan. The Clean Power Plan is its key climate change rule. It requires states and utilities to reduce carbon dioxide (CO2) emissions by generating less electricity from coal, and more from lower carbon-emitting sources like natural gas, or zero-carbon sources like solar and wind. The Plan has an ambitious goal: to reduce CO2 emissions 32% below 2005 levels by 2030.
