Benefits for carpooling

One way to make our new school environmentally friendly is to give carpoolers benefits. Some kids who have parking passes only drive by themselves, which causes there to be more cars on the roads, which causes more harmful gases to entire our atmosphere. Those who carpool with other students should receive benefits, like having clsoer parking spots to the school. This will encourage students to ride with others and it will reduce gasoline emissions. This idea is somewhat like what other states have to reduce emissions: carpooling lanes. There are specific lanes on highways devoted to only carpoolers which encourages there to be less cars on the road. More and more states are creating new ways to reduce the number of cars on the road, so why shouldn't schools do it too?
