Sources of Air PollutionMotor vehicles
◦Responsible for half of allemissions released
◦Can be fueled by gasoline,diesel, or alternative fuels

Why Should We Be Concerned?School buses drive more than 4
billion miles each year24 million American children ride
school buses dailyOn average these children spend
an hour and a half each day on the school bus

Why Should We Be Concerned?Diesel exhaust
◦Can cause lung damage and respiratory problems
◦Exacerbate asthma and existing allergies
◦Especially harmful to children because they breathe 50% more air per pound of body weight
◦Long term exposure can increase the risk of lung cancer

Clean School Bus USAAnti-idling Strategies
Turn off engine as soon as possible after arriving at loading or unloading areas
Bus should not be restarted until it is ready to depart
Limit early morning warm up to less than 5 minutes

Pollution Control Devices◦Diesel Oxidation Catalysts- uses
chemical process to break down exhaust pollutants into less harmful components
◦Diesel Particulate Matter Filters-ceramic devices that collect particulate matter

Clean School Bus USARetrofit and Clean Fuel StrategiesCleaner Fuels
◦Ultra-Low Sulfur Diesel (ULSD)- improves performance of particulate matter filter
◦Biodiesel- reduces particulate matter, carbon monoxide
◦Emulsified Diesel- reduces particulate matter and smog-causing Nitrogen oxide (NOx)

with today’s pollution control or safety features
There are over 75,000 pre 1990 buses still on the road that carry 3 million children to school

Ride the bus! For clean airDesigned to get more student on
buses and out of cars that contribute to traffic around school ground

traffic and reduce pollution

What Can We Do In Our School District?
Utilize the EPA, state, and local agencies to monitor outdoor air around schools for toxic air pollutants
Establish partnerships with school officials, bus drivers, parents, and students to improve the air quality around our schools
What Can We Do In Our School District?
Establish idle reduction policies◦Minimize time children spend outside
when buses are arriving/departing◦ If possible shorten commute times◦Deploy cleanest buses on longest routes◦Limit idling of delivery vehicles on school
grounds◦Provide space inside school where drivers
can wait on cold daysDevelop educational programs for
students of all ages about air pollution
