The administration's comprehensive climate change announcement today is being cast in bold, efficacious terms: through 2016, new CAFE standards will take the equivalent of 177 million cars off the road -- or shut down 194 coal plants.

Mindful of the economy, administration officials point to a change in the way standards are measured. No longer will they be corporation-wide; reductions will be expected in each type of automobile, which the White House believes will preserve an element of consumer choice.

Vehicles will cost about $600 more, on average, to ratchet up the standards.

As for California, its waiver request is still percolating through the federal bureaucracy. But Gov. Arnold Schwarzenegger will reportedly defer to the new federal standard. Auto companies are also on board with this -- they'll issue a statement supporting the federal standard today. ("Chrysler welcomes the President's announcement of a framework for a single national approach for fuel economy and greenhouse gas standards. We thank the Administration for their leadership.")

The administration and stakeholders have been meeting about this for weeks, although they say it is not a direct offspring of similar talks between environmental activists and auto companies brought together by the Aspen Institute.
