Denver International Airport Named Nation’s #1 Green Fleet for the First Time

DENVER – Sept. 4, 2025 – Denver International Airport (DEN) has been awarded the #1 Green Fleet of 2025 by NAFA Fleet Management Association for its outstanding efforts in reducing environmental impacts and promoting sustainability within its fleet operations. DEN competed with 59 agencies nationwide, ranging from government to commercial fleets. This is the first time DEN has been awarded top honors for its green fleet.

“Being named the greenest fleet in North America is a significant accomplishment for DEN, especially as one of the largest airports in the world,” said DEN CEO Phil Washington. “This milestone reflects DEN’s ongoing efforts to reduce emissions, invest in clean technologies and lead the aviation industry toward a more sustainable future. We remain focused on setting new standards for sustainability while maintaining operational excellence.”

For the past 18 years, the NAFA Fleet Management Association has presented the Green Fleet Awards recognizing organizations that execute groundbreaking and inventive programs for their green initiatives. Judges highlighted the airport’s use of alternative fuels and vehicles, efficient use and management of fueling and recharging facilities, and a commitment to workforce development programs in their local community. Key achievements that contributed to DEN’s recognition include:

• Expanding its EV fleet by 49% over 2024, within a total fleet of 770 units. The airport continues to order and receive additional EVs, which is expected to result in a total fleet growth of 103%.
• Conducting side-by-side comparisons of gas, compressed natural gas and electric vehicles (EV), revealing that EV’s cost 96% less to operate and reduction of 55% in Co2 emissions over CNG per vehicle.
• Installing 14 additional Level 2 charging stations and two solar powered Level 2 chargers, increasing DEN’s charging capacity for its fleet by 52% over 2024, with construction underway for a dedicated charging plaza.
