For brakes at least, electric vehicles should permit brake emmisions to be reduced significantly. First, you've got regenerative braking, so no real need to use friction brakes except when braking too hard for regen. But as you've got a good supply of electricity, most of the rest of braking could be handled by the combination of an induction brake [0] and actively powering the motors in reverse, perhaps leaving friction brakes just for emergencies.
