True, but it nonetheless encourages manufacturers to invest in zero emissions vehicles. Switching to clean energy can't happen overnight, and the real solution is population control, but it's still a signal in the right direction. Having said that, I have no strong opinion on whether humanity is smart enough limit its own growth enough to avoid decimating all the other species and the natural balance, though if I had to guess I'd say "no". We seem to be kind of like locusts that way.
