Delta’s sustainability strategy is built on three pillars: “What We Fly, How We Fly, and The Fuel We Use.” As the global airline closes out its centennial year, Delta made meaningful progress across all three, including investing in next-generation aircraft, improving operational efficiency and scaling sustainable aviation fuel (SAF). These milestones reflect Delta’s ongoing commitment to transforming the future of flight and achieving net-zero emissions by 2050, and were instrumental in driving cost savings for the company.
Check out the progress Delta made toward its decarbonization goals this year:
Delta announced a new partnership with JetZero to accelerate the development of JetZero’s blended wing-body (BWB) aircraft, a design that is expected to be up to 50% more fuel efficient than aircraft in operation today.
Delta is providing its best-in-class operational expertise through its Sustainable Skies Lab to bring the BWB aircraft to commercial viability as part of the global carrier’s work toward net-zero emissions by 2050. Delta will also consult on the interior design to re-invent and further elevate both customer and employee experiences.
Delta’s revolutionary fleet portfolio continued to grow in 2025. Delta also announced a new partnership with Maeve Aerospace to advance the development of Maeve’s hybrid electric aircraft for regional flights. Compared to today's regional aircraft designs, Maeve's aircraft design aims to reduce fuel consumption and emissions by up to 40% using conventional jet fuel, with further lifecycle emissions reductions possible when using SAF.
While Delta’s Sustainable Skies Lab continues to look toward the future by pursuing partnerships and investments to support revolutionary technologies – such as with JetZero, Maeve, and Joby – Delta also continues its fleet renewal program by investing in state-of-the-art aircraft that provide safe, reliable and premium customer experience while delivering superior fuel efficiency. In 2025, Delta is on track to take delivery of more than 35 aircraft that are on average more than 25% more fuel efficient per seat mile than the aircraft retired since 2019.
