Plano, TX — September 30, 2025—Green Taxi Aerospace and Delta Air Lines (NYSE: DAL) are entering a groundbreaking partnership to develop electric aircraft taxiing technology that aims to reduce fuel use, operating costs, taxi time, and carbon emissions. Delta’s Sustainable Skies Lab is contributing decades of airline operating experience to help Green Taxi optimize its electric taxiing system at airports for regional aircraft, though the vision extends far behind a single aircraft model or airline.

David Valaer, Founder and CEO of Green Taxi Aerospace, said, “This collaboration is about taking action today to show meaningful progress in aviation sustainability with technology that makes operations cleaner and more efficient.”

The Zero Engine Taxi™ benefits include the potential of saving hundreds of thousands of gallons of fuel as a result of more efficient taxing processes that, in turn, contribute to cost savings.

“Our Green Taxi partnership is another example of Delta’s approach to impact what we can control today while we innovate future technologies like scaling sustainable aviation fuel and revolutionary fleet development,” said Sangita Sharma, director of Delta’s Sustainable Skies Lab.

Delta is committed to a path to net-zero emissions by 2050, and with around 90% of Delta’s carbon emissions coming from jet fuel, the global airline is focusing its efforts under three pillars: ‘What we Fly, How we Fly, and The Fuel We Use.’
