Fact #555: January 26, 2009
Transit Buses are Relying Less on Diesel Fuel

In 1995, over 95% of the fuel used in transit buses was diesel. In 2006, diesel fuel constituted just under 75% of the fuel used by transit buses while other fuel types such as compressed natural gas (CNG) and liquefied natural gas (LNG) have become much more prevalent. The use of CNG in buses has grown from less than 2% in 1995 to almost 20% in 2006.
