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.
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.
The U.S. Postal Service owns more than 213,000 vehicles, the largest civilian fleet in the world. Many of these vehicles are reaching the end of their operational lives, prompting the Postal Service to wrestle with how best to address its long-term vehicle needs. A recent Government Accountability Office report noted that the organization’s current financial situation poses a significant barrier to vehicle replacement or refurbishment.
The U.S. Postal Service’s current fleet of more than 219,000 vehicles includes approximately 146,000 delivery vehicles, most of which are long-life vehicles (LLVs). The first LLVs were produced in 1987, and they average about 10 miles per gallon. The vehicles are right-hand drive to accommodate drivers delivering numerous mailpieces to curbside mailboxes. These iconic right-hand drive delivery trucks are nearing the end of a 24-year life cycle and are costly to maintain. In a recent audit, we noted that it cost the Postal Service about $524 million to fix the LLVs in fiscal year 2009.
