Climate Commitments and Reduction Targets:

Delta Air Lines is committed to achieving net-zero greenhouse gas (GHG) emissions across its operations and value chain by 2050. This commitment aligns with the United Nations Race to Zero campaign and the goals set by Airlines for America (A4A) and the International Air Transport Association (IATA).

The company has established science-based targets approved by the Science Based Targets initiative (SBTi). These include a medium-term goal to reduce well-to-wake Scope 1 and 3 jet fuel GHG emissions by 45% per revenue ton kilometre by 2035, using 2019 as the base year. Delta Air Lines also commits to annually report on its collaboration with stakeholders to mitigate the non-CO2e impacts of aviation.

Additionally, Delta Air Lines aims for a 50% reduction in net aviation CO2 emissions by 2050, relative to 2005 levels. The On-Board Services team is targeting a 10% reduction in service weight per available seat mile by 2030, compared to a 2022 base year.
