Federal agencies currently own or lease more than 660,000 cars, vans, trucks, busses, and sport utility vehicles. These vehicles consume more than 1 million gallons of fuel per day. The amount federal agencies spend on motor vehicles has increased by more than $1 billion since 2006, with 20,000 more vehicles added to the fleet over that period. The Bowles-Simpson Fiscal Commission final report recommended reducing the number of non-essential vehicles owned or leased by federal agencies other than the Department of Defense or the Postal Service by 20 percent. If adopted, this proposal could save up to $500 million over the next 10 years.
