You Can Take In Central Texas, motor vehicles are the chief cause of ground-level ozone. Any action you can take to reduce the number of miles you drive will have a positive impact on air quality. A car does not always have visible smoke from its tailpipe when it is producing excessive NOx. An auto shop can often make minor repairs resulting in better gas mileage and less pollution from your tailpipe. Keep your tires properly inflated and maintain regular tune-ups to lower your contribution to pollution.
Ozone is created by hot, sunny weather.
Refueling at the end of the day limits ozone-forming chemicals in the atmosphere. Also, avoid topping off your tank - less gasoline evaporates that way to form VOCs. Join a carpool or vanpool for your trip to and from work. Capital Metro has a database to match up potential ridesharers who live and work near each other. If you don't already, make a commitment to yourself to bike on at least one errand a week.
