Conserve energy. Conserve it at home, at work, everywhere. 2 Car pool or use public transportation. When air quality is healthy, bike or walk instead of driving. 3 Combine errands to reduce vehicle trips. Think ahead and save yourself both time and fuel costs, as well as sparing air quality from decreasing some more. 4 Limit engine idling. Idling adds more smog-inducing particles to the atmosphere. Avoid it unless absolutely essential for human health (such as keeping warm in freezing weather). 5 Refuel with care. How you refuel has an impact on air quality. To reduce this impact, consider the following steps: Stop when the pump shuts off. Putting more fuel in is bad for the environment and can damage your vehicle. Avoid spilling fuel. Always tighten your gas cap securely. 6 Keep your car, boat, and other engines tuned up. Inflate your car’s tires to the recommended pressure. This will produce the best performance for your car and reduces fuel usage. 7 Use environmentally safe paints and cleaning products whenever possible. Such paints and cleaning products emit less smog-producing particles to the air and are better for your breathing health too. 8 Follow manufacturers’ recommendations to use and properly seal cleaners, paints, and other chemicals. Carefully following the instructions ensures that smog-forming chemicals can’t evaporate.
