New York City has passed a new law requires the City fleet to use a B5 biodiesel blend in its vehicles beginning July 1, 2014 and a B20 blend starting July 1, 2016, from April to November each year, according to the Renewable Energy Group (REG). This new law will affect approximately 6,000 vehicles, according to REG.

The City also plans to launch a pilot program before Dec. 1, 2016, to study year-round use of B20 in at least 5 percent of the City’s fleet vehicles.

NYC’s Mayor Michael Bloomberg signed the legislation into law. NYC Councilman Jim Gennaro introduced this legislation, which codifies the City’s use of biodiesel in its fleet.
