E.P.A. Describes How It Will Regulate Power Plants After Supreme Court Setback
Last week’s ruling took away a major tool for reducing greenhouse gas emissions. Many regulatory options still remain, but the path will be more difficult.
A key part of the plan: Further restrict other pollutants that coal-burning power plants emit such as soot, mercury and nitrous oxides — a move that also will reduce greenhouse gas emissions.
The Supreme Court’s 6-3 decision, which concluded that the E.P.A. lacks broad authority to transform the nation’s electrical system away from fossil fuels, has left the Biden administration bereft of a powerful tool, energy experts said. The ruling did not strip the E.P.A. of its authority to regulate greenhouse gas emissions, but it allowed only narrower policies to regulate how individual power plants operate.
