The United States Postal Service (USPS) is the federal agency responsible for providing reliable, affordable, universal mail delivery across the United States. One critical element of USPS’s operations is its vehicle fleet, which had more than 235,000 vehicles in FY2022, including specialized local delivery trucks, passenger cars, and tractortrailers.
In FY2022, fuel consumption was 221 million gallons of gasoline equivalent, with gasoline or diesel making up 99%. USPS fleet greenhouse gas emissions (GHGs) made up 70% of overall GHGs for federal fleet vehicles in FY2022. Modernization of the USPS fleet is of interest to many in Congress, with several bills introduced and hearings held in recent Congresses regarding modernization of USPS’s fleet.
