Clean Heavy-Duty
Vehicles Program

Over three million Class 6 and 7 vehicles, such as school buses,
1 delivery trucks, refuse haulers/dump trucks and utility trucks,
are currently in use. Most emit diesel exhaust containing
harmful pollutants.1

Funded through the Inflation Reduction Act,
this program invests $1 billion to replace
non-zero-emission heavy-duty vehicles
with zero-emission vehicles and refueling
infrastructure.*

23%^ Medium- and heavy-duty vehicles account for 23% of greenhouse gas (GHG) emissions
1 within the transportation sector2, but only account for 10% of vehicles on U.S. roads.3
The majority are non-ZE vehicles powered by internal combustion engines that pre-date
recent EPA emission standards.

Exposure to exhaust
including nitrogen oxide
(NOx) and fine particulate
matter (PM2.5) can
lead to serious health
conditions like asthma.

This pollution

can worsen
existing heart
and lung disease,
especially in children
and the elderly.
