How municipalities and fleets improve their operations with biodiesel.
According to a 2016 Fleet Purchasing Outlook study conducted by the NTEA — The Association for the Work Truck Industry — biodiesel is now the most common alternative fuel option used by fleets.See how some of the nation’s biggest municipalities put biodiesel to work for them.
New York City
Since 2013, the New York City Department of Parks and Recreation has used B20 as its standard fuel in 850 diesel-powered vehicles. Today New York City uses more than 13 million gallons of biodiesel every year to power 9,000 vehicles in its fleet.
"We used B5, and in some cases B20, successfully across all of our operations with no real operational problems. Even during the polar vortex, when temperatures got colder than they have been in decades."
Keith Kerman
Chief Fleet Officer, Deputy Commissioner, City of New York
Chicago
The Chicago Park District runs about 160 pieces of equipment with 6,000 gallons of biodiesel every year, including garbage trucks, mowing units and beach tractors. They use a B20 blend through the end of October before going to a B5 blend during winter.
"We want to be leaders, we want to implement sustainable practices, we want to be innovative and we want to roll it out and demonstrate that it’s what’s happening."
Michael Dimitroff
Former Area Manager, Chicago Park District
San Francisco
The city cut its greenhouse gas emissions by 60 percent3 in 2015 by replacing petroleum diesel with renewable hydrocarbon diesel in its fleet.
