Most forms of transportation contribute to air pollution. Driving less, taking the bus or riding a bicycle are good habits to reduce your own emissions. And you can help with bigger changes, such as supporting improved fuel efficiency in cars, reduced idling of diesel school buses, transitioning bus fleets to clean energy and promoting public transportation.
