Ramesh – The problem with Dean’s statement is that he assumes that projected emissions reductions will be achieved on schedule under current law. This is nuts. As Gregg Easterbrook commented when environmentalist groups made the same charge: “Anybody who today thinks that existing Clean Air Act power plant rules for future decades are going to be implemented exactly on time either doesn’t know the history of air pollution control or is bluffing for reasons of doomsday spin.” Central to the Bush Administration’s argument is that Congressional adoption of the Clear Skies initiative will provide more certain emission reductions at lower cost than business as usual — a perfectly reasonable assumption. Even though I have some misgivings about Clear Skies, I believe the administration is correct that their plan will produce greater emission reductions than one can reasonably expect to actually occur under current law.
