Government support has also played a role in expanding the SAF market. Delta has worked with federal and state agencies to advocate for policies that facilitate SAF production. This year saw several advancements, including government loans for large-scale production facilities and grants for blending capabilities.

In addition to these efforts, Delta made strides in reducing single-use plastics on flights by introducing paper cups on international routes and transitioning earbud packaging from plastic to kraft paper. Technological innovations like TaxiBot are being tested to further reduce jet fuel consumption during taxiing operations.

At its Atlanta headquarters, Delta implemented campus greening initiatives such as installing solar panels and additional electric vehicle charging ports. These measures contribute to sustainable energy use at their facilities.

The airline also signed an agreement with AeroCore Technologies for foam engine washing technology expected to save millions of gallons of fuel annually by improving engine performance.

Delta's commitment extends beyond current operations as it supports Boeing’s X-66 Sustainable Flight Demonstrator program. This initiative explores new aircraft designs that could enhance fuel efficiency through reduced drag.

To ensure continued progress, Delta established cross-divisional councils focused on sustainability initiatives like SAF scaling and green practices across corporate accounts. Additionally, new operational KPIs were introduced this year to engage employees in sustainability efforts actively.

As it approaches its centennial anniversary next year, Delta remains dedicated to pursuing net-zero emissions by 2050 through collaborative efforts within the aviation industry and beyond.
