An energy pilot program at Westchester County Airport in New York has confirmed that renewable diesel delivers both financial and environmental benefits. The county tested the biobased fuel on 64 pieces of ground service equipment through all four seasons, and found that renewable diesel performed seamlessly while saving money.
County analysis shows renewable diesel was 17 percent less expensive than regular diesel in 2025, demonstrating fiscal responsibility for airport stakeholders. With the trial now concluding, the County will fully transition its airport fleet to renewable diesel, replacing traditional fuel with a cleaner and more cost-effective alternative.
County Executive Ken Jenkins said, “This pilot demonstrates that we can be responsible stewards of services to the public, while still advancing ambitious sustainability goals. Renewable diesel is lowering our costs and reducing our carbon footprint, proving that efficiency and environmental progress are not mutually exclusive.”
Deputy County Executive Richard Wishnie said, “Westchester is leading by example. This pilot program demonstrates how local governments can adopt sustainable practices that not only protect the environment but also deliver tangible savings for stakeholders.”
Director of Energy Conservation and Sustainability Peter McCartt said, “What makes these results so important is that renewable diesel is a practical, ready-to-use solution available now. It enables us to reduce greenhouse gas emissions without compromising performance or incurring additional expenses. I’m reticent to use the term bridge fuel, but this will truly help Westchester reach its long-term energy goals.”
Director of Aviation April Gasparri said, “At Westchester County Airport, we are committed to running safe and efficient operations while reducing our environmental impact. This trial confirmed that renewable diesel is a reliable and cost-saving solution, and we are proud to make it part of our long-term sustainability plan.”
Officials noted that Westchester County’s adoption of renewable diesel sets an important example for other municipalities and industries exploring alternative fuels.
