Fueling a Fleet

Alternative fueled vehicles are gaining renewed interest with the abundance of cheap, domestic natural gas. Compressed natural gas (CNG) vehicles took off in the 1990s as infrastructure development surged. Service stations then declined for a decade but are now resurging. Liquefied natural gas and ethanol are other options, as is a new clean fuel called GDiesel, a combination of conventional diesel and natural gas that can be used on conventional diesel engines without modifications.


Fuel For Thought

The Postal Service is a leader among federal agencies in sustainability efforts. In 2009, it joined with 20 international postal operators to commit to a 20 percent reduction in carbon emissions by 2020, a goal it has made significant progress toward achieving. A major contributor to greenhouse gas emissions is vehicle emissions. With the largest civilian fleet in the country – more than 213,000 vehicles – the Postal Service has both an enormous opportunity and an enormous challenge in reducing its fuel consumption. So far, the challenges have proved considerable.


Enhancing Mail Visibility with GPS

With so much technology at their fingertips, customers now want and expect complete visibility of their mail, from entry to delivery. The Intelligent Mail barcode (IMb) program has helped to bring total visibility closer to reality, and other technologies, such as radio frequency identification (RFID) and global positioning system (GPS) tracking, can fill the gaps. Complete visibility of mail provides real-time information about mail to customers and the U.S. Postal Service, including service performance data.
