Clean Air for Schools: Engines Off!

Clean Air for Schools: Engines Off (CASEO) is a partnership between federal and local governments, schools and non-profits in Colorado to reduce the amount of vehicle idling during school pickup times. CASEO is an educational and curriculum-based program that has been implemented at over 40 schools in Colorado and has reduced idling by 60% on average for those schools.  Lungs continue to develop until age 18, and when children are exposed to air pollution, it stunts lung growth and can lead to a predisposition to infection later in life. Kids also have a faster rate of respiration, spend more time outdoors, and are more active than their adult counterparts- all reasons why we should do our very best to clean up air around schools.

If you are interested in implementing this program at your child's school, contact us

Facts About Idling

  • For mordern cars with fuel injection, idling for more than 10 seconds uses more gas and emits more CO2 than restarting the engine.1
  • From idling alone, almost 3 billion gallons of fuel are wasted annually, costing drivers $10 billion or more.1
  • Idling pollutes the air outside and in your vehicle. Pollution from exhaust contributes to healh issues such as lung infections, pneumonia, influenza, and asthma.2
  • Most people waste 1-2 entire tanks of gas every year by idling.3
  • Just 1 minute of idling puts more carbon monoxide into the air than 1.5 packs of cigarettes. 4,5
