This is a great tip now that we are in the swing of things with the children back to school!  Idling your car or school bus wastes energy!  Remind your school system to turn off bus engines when buses are parked. Exhaust from idling school buses can pollute air in and around the bus, and can enter school buildings through air intakes, doors, and open windows. Constant idling also wastes fuel and money, and school bus engines really need only a few minutes to warm up.  Try to turn your car off as well when you are waiting to pick children up from school - or any other time you are sitting in the car waiting!
