Government regulation produces things like CAFE and Energy Star. They can work to some degree but the incentive to create back doors around them (I don't drive a car I drive a light truck) is enormous - doubly so because people have no commitment to the principle they try and serve because they aren't asked to have any commitment instead government tries to trick people to go along with the principle. I'm buying an energy efficient furnace that costs more then it otherwise might because those are the only furnaces available to be purchased. It can work but only to a limited degree, if you really push the thing then it becomes more likely that people will catch on to the "trick" and elect people who will undo it. They'll do that happily because there's no commitment.
