DCAS and NYC DOT Announce First Barge Delivery of Renewable Diesel, Marking the Staten Island Ferry’s Full Transition to Cleaner Energy
June 17, 2025
A shipment containing 336,000 gallons of Hydrogenation-Derived Renewable Diesel – a sustainable alternative to petroleum-based fuel – has now arrived in Staten Island.
NEW YORK – Today, the Department of Citywide Administrative Services (DCAS) and the Department of Transportation (DOT) announced the official start of the Staten Island Ferry’s transition to renewable diesel, marked by the delivery of the first barge of fuel to the ferry system. This first shipment, totaling 336,000 gallons, begins the full replacement of petroleum diesel with a more sustainable alternative. The Staten Island Ferry fleet uses approximately 4.5 million gallons of fuel each year, and the transition supports the City’s commitment to reduce greenhouse gas emissions by 50 percent in 2030.
“New York City has one of the best ferry systems in the world, and the Staten Island Ferry is no exception. Today, we take the next step to modernize this critical fleet by transitioning to sustainable, renewable diesel,” said New York City Mayor Eric Adams. “The more than 45,000 New Yorkers who use the Staten Island Ferry each day will now travel powered by clean energy. This is just our latest effort on this front — our administration is laser-focused on making our entire city safer, cleaner, and greener every single day.”
“This delivery marks another tremendous milestone in our mission to make the City’s fleet cleaner and more sustainable,” said DCAS Commissioner Louis A. Molina. “Having successfully transitioned the City’s heavy-duty and offroad fleet to renewable diesel, we have expanded its use to the Staten Island Ferry fleet, cutting emissions and proving that green transportation is achievable at a large scale.”
“The Staten Island Ferry is the busiest municipal ferry service in the country, and today’s announcement offers a key step towards a cleaner and healthier New York City.” said NYC DOT Commissioner Ydanis Rodriguez. "When we all work together to green our transportation system, we can achieve our climate goals faster, showing the rest of the country how it can and should be done.”
“In the last three years, we worked with each agency operating trucks to coordinate the transition to cleaner renewable diesel,” states DCAS Deputy Commissioner and NYC Chief Fleet Officer Keith Kerman. “We are now doing the same with the City’s vessel programs including at DOT, DEP, NYPD, FDNY, EDC, and Parks. By July 2026, all city trucks and vessels will use renewable diesel and be powered by used cooking oil and waste tallow.”
In October 2024, DCAS and DOT first announced plans to test the use of renewable diesel with the ferry fleet, following the successful transition of the City’s heavy-duty and offroad vehicles. Since then, the agencies have successfully used more than 1.1 million gallons of renewable diesel across the ferry fleet. While inspecting internal engine components, NYC DOT found that using renewable diesel led to cleaner equipment with less carbon buildup compared to previous inspections conducted at similar times using non-renewable diesel. The renewable fuel being used is primarily made from waste materials, such as cooking oil and tallow. In March, DCAS finalized a new fuel contract to support this transition, marking the first renewable diesel contract that references the Argus RD index price for the New York Harbor, ensuring that the fuel aligns with the market value.
“The Staten Island Ferry is more than a mode of transportation it is part of our identity. This transition to renewable diesel marks a monumental step toward cleaner air, a healthier harbor, and a greener future for Staten Island,” said Council Member Kamillah Hanks. “As a community that has been deeply affected by climate change, we understand the urgency of this moment. I commend the New York City Department of Citywide Administrative Services and the New York City Department of Transportation for their leadership in advancing sustainability and protecting the health of our environment and our community.”
“The transition of the Staten Island Ferry to 100 percent renewable diesel is a powerful testament to our climate goals and shows that New York City is leading by example on clean transportation,” said Council Member James Gennaro. As Chair of the Committee on Environmental Protection, Resiliency & Waterfronts, I applaud DCAS and DOT for their leadership in helping our city achieve this important milestone. By cutting emissions from one of our city’s busiest transit systems, we are demonstrating our commitment to a cleaner, healthier, and more sustainable NYC.”
“The Staten Island Ferry is an essential service that thousands of our residents rely on each day to stay connected to the rest of the city,” said Assemblyman Charles D. Fall. “Any improvements that enhance public health, safety, and quality of life for riders are a welcome investment in the well-being of our entire borough.”
DCAS is also working closely with other agencies to further expand the use of renewable diesel across the City’s marine operations, including the Department of Environmental Protection (DEP), the New York City Police Department (NYPD) Harbor Patrol, NYC Parks marinas, and the New York City Fire Department (FDNY) to test the fuel and expand usage further. To date, the City has used 27 million gallons of renewable diesel across its fleet and ferries, ranging from diesel vehicle units, on and off road, and non-emergency vehicles. The City’s goal is to transition all municipal vessels by June 30, 2026.
These advancements reflect DCAS’ ongoing efforts as a national leader in sustainable, safe, and efficient fleet operations, managing the largest electric vehicle (EV) fleet and charging networks in New York State, with 5,500 EVs and 2,250 chargers respectively. This month, DCAS and FDNY unveiled the purchase of 30 all-electric vehicles, marking the latest large-scale investment in sustainable fleet while advancing citywide emission reduction goals. DCAS is also the first large fleet on the East Coast to completely transition from fossil diesel fuel to renewable diesel. Moving forward, DCAS remains committed to transforming the City’s fleet with more innovative technologies and effectively developing a greener, and safer New York City for all.
