We've focused on effeciency from the get-go. Today we're working even harder: greener choices with the U.S. Postal Service®

Finding ways to cut back

  • We use water-based inks to print stamps.
  • We use refined bio-based oil, alternative fuels such as compressed natural gas, hydrogen, or ethanol gas, and re-tread tires on our fleet of Postal vehicles
  • We’re constantly streamlining our delivery routes to reduce driving time and fuel use.

Promoting alternative fuels

The Postal Service has the largest civilian vehicle fleet in the nation and over 43,000 of them are alternative-fuel capable. Our E-85 alternative-fuel project put 584 ethanol-powered vehicles on the road in Minnesota alone. Since we primarily refuel at commercial retail fueling locations, our fleet generates demand for alternative fuels nationwide.

Encouraging vehicle technology

General Motors and the Postal Service worked together to test the GM HydroGen3 fuel cell minivan for deliveries in the Washington, D.C. metro area and Irvine, CA — the first commercial use of a fuel cell vehicle in the nation. Our other vehicle technology efforts include advanced diesel vehicles, hybrid electric vehicles, and electric CitiVans, which are recognized by the EPA as zero emission vehicles.

Other ways we reduce energy

  • We are upgrading our buildings to reduce energy use. Our objective is to reduce our energy consumption 30% by 2015.
  • We deliver the mail in the most energy-efficient way possible — a third of our deliveries are made on foot.

The result: We’re making a smaller footprint.
