EPA CLEAN SCHOOL
BUS PROGRAM

School buses travel over four billion miles
each year, providing the safest transportation
to and from school for more than 25 million
children everyday. However, diesel exhaust
from these buses can contribute to air quality
problems and 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.

The Bipartisan Infrastructure Law provides
$5 billion over the next five years (FY22-26)
to clean a substantial portion of the nation's fleet
of nearly 500,000 school buses. These new
cleaner school bus replacements will produce
either zero or low tailpipe emissions compared
to their older diesel predecessors. School bus
upgrades funded under this program will result
in cleaner air on the bus, in bus loading areas,
and in the communities in which they operate.

Under the Clean School Bus Program, half
of the available funding is dedicated for zero-
emission school buses and half is for clean
school buses.

¦	Zero-emission school bus: a school bus
that produces zero exhaust emission of
any air pollutant and any greenhouse gas.

¦	Clean school bus: As defined by the BIL,
a school bus that reduces emissions and
is operated entirely or in part using an
alternative fuel or is a zero-emission bus.
