A Local Law to amend the administrative code of the city of New York, in relation to the use of renewable diesel fuel

This local law amends the administrative code of New York City to mandate the use of renewable diesel fuel (RD) or a blend of RD with no more than 5% biodiesel (B5) for all city-owned or operated diesel fuel-powered motor vehicles, effective July 1, 2026. This replaces previous requirements for ultra-low sulfur diesel fuel blends containing higher percentages of biodiesel. The law also requires the Commissioner of Environmental Protection to submit an annual report detailing the types of fuel used by the city's diesel fleet, including the number of vehicles powered by RD or RD blends. Waivers for fuel availability or warranty concerns are permitted for up to two months, subject to renewal. The bill also updates definitions related to renewable diesel and best available retrofit technology.

This legislation aims to reduce greenhouse gas emissions from the city's vehicle fleet by transitioning to renewable diesel fuel. Residents may benefit from improved air quality and the city's progress towards its climate goals, with no direct cost impact.
