PREVENTING OZONEOn the Road

You’re in the driver's seat to reduce Ozone Pollution.

Ozone and vehicles. Did you know that vehicles contribute to about one third of all ozone-causing emissions in the Denver area? These emissions are produced by the cars and trucks we drive everyday. But we can lower the impact on our air by improving their maintenance, reducing the number of miles traveled each day, and making public transportation a priority. You can find more information below about how to participate in some of the great programs already running smoothly around town.

Don’t be Idle.  An idling vehicle gets the worst gas mileage possible – 0 MPG.  We hope to dispel many myths about idling vehicles, including the idea that you use more fuel turning your car on and off. That is simply not true.  If you plan to idle for more than 30 seconds, please turn off your engine. For more information, visit the Denver coalition web site at www.Enginesoff.com.

Easy Fixes.  Vehicles that run on diesel fuel are as sturdy as they come.  Often though, these vehicles produce high levels of pollution that can be easily reduced by retrofitting simple exhaust system components and adding idling reduction technology.  The RAQC and its partners have a robust retrofit program designed to reduce emissions from school buses, semi-trucks, government and commercial fleets as well as heavy duty vehicles. These projects help to reduce pollution by changing parts out instead of having to replace the vehicles all together.  For more information, visit www.CleanAirFleets.org

Transport Yourself Differently. There are many alternative ways to get around other than single-occupancy vehicles.  The RAQC is spearheading an effort to get people out of their cars only two trips per week.  To find out more information, visit Every Trip Counts.  The Denver Regional Council of Governments has additional information about other programs and efforts throughout the Denver-metro region at their website. 

Tips for summer drivers:

  • Keep your car tuned up and tires well inflated to increase mileage and reduce the need for refueling.
  • Refuel in the evening, so fuel vapors will not have a chance to “cook” into ozone.
  • When refueling your car, stop at the click -- when the nozzle clicks off. Don't overfill or drip fuel. Fuel creates ozone-causing vapors as it evaporates.
  • Avoid idling your car unnecessarily while waiting in parking lots or service lines. Turn off the engine instead.
  • Reduce your driving by delaying trips, combining errands into one trip, carpooling, walking or biking, or using public transportation.
  • Make a Smart Vehicle Choice. Choose an alternatively fueled vehicle or one that gets good gas mileage the next time you are buying or renting a car.
