President Obama's goal of updating the federal fleet with greener vehicles is a trend-setting proposition, as five major companies – UPS, FedEx, Verizon, AT&T and Pepsi – will also commit to upgrading their fleets: 

The two transport companies along with AT&T, PepsiCo and Verizon are charter members of a National Clean Fleets Partnership group that aims to reduce use of diesel fuel and gasoline in their companies' cars and trucks by using electric vehicles and alternative fuels.

The five companies are pledging to reduce their collective petroleum consumption by more than 7 million gallons a year by deploying 20,000 hybrid and other types of vehicles that run on biofuels, electric power and other advanced technologies, the White House said in a statement.

The effort is part of Obama's newly announced goal of reducing U.S. imports of foreign oil by one-third by 2025.

The companies represent five of the United States' largest national fleets with more than 275,000 vehicles owned and operated between them, it said.

President Obama's administration is encouraging other companies to also join in the effort, and the Department of Energy will offer technical expertise, resources and support to assist the companies in their fleet upgrades.
