Tips for cutting emissions on ozone alert days:

  • Ride the bus. Each bus can take 35 cars off the road. According to the APTA,* for every mile traveled on public transit, riders produce 95% less carbon dioxide than driving.
  • Carpool. Carpooling can cut the number of cars in the road by at least half. Talk to your friends and coworkers to find people who live or work near by and share the drive. To learn more about carpooling or to be matched with someone in your area, visit
  • Combine trips. Before running errands, plan ahead. Try to combine as many errands into one trip as possible.
  • Take your lunch to work. Packing a lunch is a simple way to cut out a trip during the hottest time of the day.
  • Dine-In or Walk-Thru. Avoid idling your engine in line at the drive-thru.
  • Teleconference. Instead of driving to meetings on ozone alert days, consider teleconferences.
  • Fill up your tank in the evening. Refueling in the evening can prevent gas fumes from heating up and evaporating into the atmosphere. And don?셳 top off your tank to prevent releasing fumes into the air.
  • Avoid mowing or mow in the evening. According to the Association of Central Oklahoma Governments, older two-cycle gasoline-powered lawn mowers running for one hour emit as many pollutants as a car driven from Oklahoma City to Houston.

About ozone.

Under the Clean Air Act, the Environmental Protection Agency can set air quality standards which provide protection for children and at-risk populations from pollution and ozone related health effects. Right now, Oklahoma is within those guidelines, but only marginally.

Motor vehicles are a prime contributor to air pollution. One of the best ways to improve air quality is to get people out of their single-passenger cars and into carpools and public transportation.

Compliance with the Clean Air standards is not only beneficial for our health, it?셲 also good for businesses. According to the U.S. Chamber of Commerce, consequences of non attainment can result in increased gas prices, mandatory emissions offsetting, more strict building permits and loss of federal transportation funding.

Hot temperatures, calm winds and sunshine with no cloud cover are the ingredients for an ozone alert day in which citizens are asked to do their part to keep pollution down.
