In this year’s Sky Team Alliance Sustainable Flight Challenge, Delta took home two top prizes as they are celebrated for their sustainability efforts.

Delta won awards for the Lowest CO2 Ground Emissions Home Base for electric ground support and Best Innovation Wildcard for several high-quality submissions.

The judges delivered the results at a gala on Tuesday, attended by participating airlines and a number of industry partners. Delta was also a finalist in both Best in Innovation and Lowest CO2 Emissions Ground Ops categories.
