"Assemblywoman Shirley Horton (R. San Diego) introduced California Assembly BILL A.B.2899 in February of 2004. This bill seeks to level the playing field in California by removing restrictions on the sale of biodiesel enacted by the Department of Weights and Measures... The bill would specify standards for the sale biodiesel and biodiesel blends and establish a program of voluntary CO2 content labeling program."

Update: Berkeley Daily Planet: "Despite efforts by both the Engine Manufacturers Association and ChevronTexaco Corporation to put roadblocks in the bio-diesel fuel regulation process, the California Department of Weights and Measures has opted only to regulate the fuel more thoroughly, not ban it outright."
