  3. Reduce Student Exposure to Toxic Vehicle Exhaust - Go Idle FREE for Kids and Polar Bears

The Idle-Free Schools Toolkit includes information needed to run an effective idle reduction campaign at a school to reduce student exposure to toxic vehicle exhaust. Monitoring at schools has shown elevated levels of air toxins during the afternoon hour coinciding with parents picking up their children. Idling vehicles contribute to air pollution and emit air toxins, which are pollutants known or suspected to cause cancer or other serious health effects.

EPA Idle-Free Schools Toolkit

The Toolkit provides the resources to make this a student-run science or community involvement project, providing students with the opportunity to learn how to run a public service campaign while expanding their science and math skills.

Children’s lungs are still developing, and when they are exposed to elevated levels of these pollutants, children have an increased risk of developing asthma, respiratory problems and other adverse health effects. Limiting a vehicle’s idling time can dramatically reduce these pollutants and children’s exposure to them.

Why Not Idle?

Car exhaust contains air toxics, which are known to cause cancer, respiratory effects, reproductive effects, birth defects or other serious health effects.

Because of their developing lungs and higher breathing rates, children are more susceptible to air pollution.

If many vehicles are idling at once, for example in school pick up/drop off areas, a “hot spot” of exhaust pollution can be created.

Monitoring at schools has shown elevated levels of air toxics during the afternoon hour coinciding with parents picking up their children.


Idling Facts

The chemicals from exhaust are harmful and can make asthma worse.

Most people waste 1-2 entire tankful of gas every year by idling.

Ford Motor Company says: “Avoid idling more than 30 seconds because excessive idling can actually damage your engine.

Idling more than 10 seconds uses more fuel than restarting the engine.

Manufacturers assure that frequent restarting won’t harm an engine.

What can you do?

If you are going to wait more than 10 seconds, turn your vehicle off.

It’s as simple as that. 

Pledge to not idle unnecessarily

anyplace, anytime.
