​CHICAGO – April 13, 2021 – United Airlines continues to lead the industry towards a more sustainable future with the launch of the first-of-its-kind Eco-Skies Alliance SM program. Working with the airline, more than a dozen leading 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% 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.
