Cars emit the most pollutants when accelerating. If the lights are synchronized to allow the heaviest flow of traffic to move without stopping and starting the need for acceleration is minimized and pollution reduced.
An added benefit is that, since cars also emit more pollution when idling, unless they turn off their engines, allowing more cars to travel in their most efficient engine speed range is enhanced by light sychronization.
