Use your car air conditioner wisely. Air conditioning is a drag on your car's engine, reducing gas mileage by as much as 20 percent. Have leaks in your car air conditioner fixed by a certified technician using required CFC recycling equipment. Consider buying fuel efficient cars. What You Can Do at Home and at Work Conserve electricity.
Electricity generation can be a major source of air pollution.
Use energy-efficient lighting and appliances in your home or office, and make sure lights and appliances are turned off when not in use. Raise the temperature level of your air conditioner a few degrees in summer, and turn down the heat a few degrees in winter. Buy fuel-efficient motorized equipment. If you are buying a power mower or other motorized garden tools, construction or farm equipment, or outboard motors, seek out those that are designed to minimize emissions and reduce spillage when being refueled. Avoid spilling gas.
