Programs to Reduce Vehicle Idling
Idling vehicles waste fuel and emit air pollutants that can cause serious health effects. Buses and parents’ vehicles idling during school drop-off and pick-up can produce concentrated exhaust emissions not only outside school buildings, but also inside: Exhaust can be pulled into a school through the air intakes of the building’s ventilation system where it can accumulate and cause serious health issues for staff and students. Diesel exhaust from aging school buses has a negative impact on human health, especially for children who have a faster breathing rate than adults and whose lungs are not yet fully developed. While new buses must meet EPA’s tougher emission standards, many older school buses continue to emit harmful diesel exhaust that produces hazardous pollutants and significant levels of particulate matter that can cause lung damage and aggravate respiratory conditions such as asthma.
Taking action to address car and bus idling can positively impact air quality and the health of students and staff as well as reduce fuel costs, energy costs and unnecessary engine wear. Learn more about how to implement healthier transportation policies like establishing “Idle-Free Zones”, locating passenger pickup and drop off areas away from a school’s air intake supply and classroom windows, starting a carpooling program and encouraging active transportation like walking and biking.
