United Airlines is launching a first-of-its-kind Eco-Skies Alliance program.

Working with the airline, more than a dozen global corporations will collectively contribute towards the purchase of approximately 3.4 million gallons of sustainable aviation fuel (SAF) this year.

With its nearly 80 per cent emissions reductions on a lifecycle basis compared to conventional jet fuel, this is enough SAF to eliminate approximately 31,000 metric tons of greenhouse gas emissions, or enough to fly passengers over 220 million miles.

As inaugural participants, the companies are taking a lead within their respective industries, reducing their aviation-related impact on the environment at the source, and creating demand for more SAF production.

Companies involved include Autodesk, Boston Consulting Group, CEVA Logistics, Deloitte, DHL Global Forwarding, DSV Panalpina, HP Inc., Nike, Palantir, Siemens and Takeda Pharmaceuticals.

“While we’ve partnered with companies for years to help them offset their flight emissions, we applaud those participating in the Eco-Skies Alliance for recognising the need to go beyond carbon offsets and support SAF-powered flying, which will lead to more affordable supply and ultimately, lower emissions,” said United chief executive, Scott Kirby.

“This is just the beginning.

“Our goal is to add more companies to the Eco-Skies Alliance program, purchase more SAF and work across industries to find other innovative paths towards decarbonisation.”

In addition to the Eco-Skies Alliance program, United is giving customers the ability to contribute funds for additional SAF purchase or for use on initiatives.
