Why not just make any type of vehicle illegal to own or drive. And they would include everything but the military and the politicians would not be allowed to use their stuff to travel. After a few years and the saw just how little that changed things, maybe one or two of the ones with a brain would figure out that just vehicle emissions are not the major contributing cause to the mostly media hyped panic. But the longer they can keep this going the more money they can rake in and we could also eliminate all the groups making money of this with their phony studies. Just think of the savings. And how hard it would be for Ted Kennedy to ride a bicycle, but at least he would have a hard time drowning his girl friends.
