City-owned vehicles to use biodiesel fuel
by: Cecilia M. Vega 19 May 2006
City-owned vehicles in San Francisco, including fire engines, buses and even a mobile zoo, will use biodiesel fuel that reduces harmful emissions under an executive directive issued Thursday by Mayor Gavin Newsom.
The order calls on city departments that currently use diesel fuel in vehicles and equipment to switch to biodiesel fuel in 100 percent of their fleets by the end of 2007.
Biodiesel fuel is renewable, made from such products a soybean or cooking oil and typically can be used in existing diesel engines without requiring major modifications.
The San Francisco Fire Department announced a six-month pilot program Thursday to test the use of biodiesel fuel on nine engines, trucks and an ambulance. Other city departments that also have tested and use biodiesel in vehicles include San Francisco International Airport, Public Works and Muni, as well as San Francisco Zoo in its van service that brings animals to children around town.
