Self-driving in itself won't help, but it's much more feasible for a fully autonomous system of cars to be totally electric since you can plan for the charging logistics as part of the system's design. A walkable, pro-self-driving-car city could also theoretically tax self-driving-car rides to offset environmental impact.
