Biodiesel’s heart is in San Francisco now that it has become the largest U.S. city to institute citywide use of B20. According to a release from the National Biodiesel Board, San Francisco Mayor Gavin Newsom issued an Executive Directive designed to increase the pace of municipal use of biodiesel in the city which uses about 8 million gallons of diesel a year. Among other things, the directive states that all diesel-using departments shall begin using a B20 biodiesel blend as soon as practicable in all diesel vehicles and other diesel equipment, with the following incremental goals in each department’s use of B20: initiate and complete biodiesel pilot project by December 31, 2006; 25% by March 31, 2007; 100% by December 31, 2007.
