School Bus Sector
West Coast Collaborative Clean School Bus
USA Request for Proposals Is Now Closed
The West Coast Collaborative
requested proposals aimed at reducing diesel emissions from
school buses operating in the Regions 9 and 10 states. The
application deadline has now passed. We look forward to reviewing
Clean School Bus USA
The goal of Clean School Bus USA is to reduce both children’s
exposure to diesel exhaust and the amount of air pollution created
by diesel school buses. Clean School Bus USA brings together
partners from business, education, transportation, and public
health organizations to work toward these goals:
- Encouraging policies and practices to eliminate unnecessary
public school bus idling.
- Upgrading ("retrofitting") buses that will remain
in the fleet with better emission control technologies and/or
fueling them with cleaner fuels.
- Replacing the oldest buses in the fleet with new, less polluting
Statistics show that school buses are the safest way to transport
children; the EPA wants to ensure that they are also the
cleanest. There are an estimated 400,000 diesel school buses
on the road, with roughly one third manufactured before 1990.
The pre-1990 school bus fleets are the heaviest polluters and
should be replaced. The remaining school buses, manufactured
between 1990 and 2006, can be made much cleaner by installing
devices designed to reduce pollution and switching to cleaner
Children are especially sensitive to air pollution because
their respiratory systems are still developing and they breathe
at a faster rate. More than 24 million children ride in school
buses daily, spending, on average, an hour and a half each
weekday on the bus. Recent studies suggest that children’s school
bus commutes can expose them to significantly higher concentrations
of pollutants than what is measured in a community’s outdoor
Since 2001, the EPA has awarded over $6.8 million to clean up school buses in the West. The projects to date in the West have leveraged nearly $15 million in additional matching funds and in-kind services.
