School Bus Loop


School buses travel about four billion miles each year, and more than 25 million American students ride a school bus every day. These buses provide the safest transportation for getting children to and from school. While all new buses must meet EPA's tighter emission standards, many older school buses continue to emit harmful diesel exhaust. Diesel exhaust has a negative impact on human health in general, and especially on children because they have a faster breathing rate than adults and their lungs are not yet fully developed.

One of the easiest ways to reduce school bus emissions, and to save money, is to reduce idling. Many local jurisdictions have codes that restrict vehicle idling, which also applies to school buses. By replacing the oldest school buses in the fleet, emissions can also be reduced. Visit the links above to identify federal grants. Retrofitting existing fleets to use bio diesel is another way to reduce diesel emissions. Bio diesel is diesel fuel oil modified with 0 to 100% biologically derived oils.
