Limit driving whenever possible. Use public transit, car pool, walk, or ride a bike instead of driving. Do not refuel your car on hot days, or only do so after 7 p.m. 3. Do not idle your vehicle's engine. Idling for just 30 seconds uses more fuel than stopping and starting your engine.
Small engines are a significant source of air pollution.
Get regular engine tune-ups and keep the right amount of air in the tires. Well maintained vehicles pollute less. Take your lunch to work to reduce lunchtime trips, and combine errands to reduce miles driven. When you barbecue, use an electric or chimney-type fire starter instead of lighter fluid. Avoid using oil-based paints, solvents, cleaners, or varnishes.
