The Obama administration is expected to announce today new restrictions on U.S. power plants that are, in the words of the New York Times, “the strongest action ever taken in the United States to combat climate change.” In reality, the new regulatory regime is no such thing, a fact that ought to inform the years-long political and legal fight that the president’s unilateral rulemaking inevitably will provoke.
The president will instruct U.S. power plants to reduce their carbon dioxide emissions by just under one-third (32 percent). How that is to be achieved and at what cost is . . . not Barack Obama’s problem. States will have until 2018 — comfortably remote from any presidential election — to submit their plans, and until 2030 to implement them.
