On the ground and in the air, we Keep Climbing: Delta’s year of sustainability progress

Delta made meaningful progress toward its decarbonization goals in 2025, including investing in next-generation aircraft, improving operational efficiency and scaling sustainable aviation fuel (SAF).

Sustainable aviation fuel (SAF) is the most promising lever known today to accelerate progress toward a net zero future – it can use the existing fuel infrastructure to get it to airports and is safe to use in current aircraft engines. And, importantly, the use of SAF has the ability to reduce emissions by up to 80% with the potential for net negative emissions in certain circumstances.
