Delta Air Lines

Delta Air Lines, an air transport services company headquartered in the US, reported approximately 62.28 billion kg CO2e in total emissions for 2025. This includes about 39.30 billion kg CO2e from Scope 1 emissions, primarily from mobile combustion, 116.11 million kg CO2e from Scope 2 (location-based), and approximately 22.86 billion kg CO2e from Scope 3. Key contributors to Scope 3 emissions were investments (7.18 billion kg CO2e), capital goods (2.30 billion kg CO2e), and fuel and energy related activities (10.03 billion kg CO2e).

The company has set several climate commitments. Delta Air Lines aims to achieve net-zero greenhouse gas emissions across its airline operations and value chain by no later than 2050, aligning with the United Nations Race to Zero campaign and goals set by Airlines for America (A4A) and the International Air Transport Association (IATA).

Delta Air Lines has also had its medium-term targets approved by the Science Based Targets initiative (SBTi). These targets commit the company to reduce well-to-wake Scope 1 and 3 jet fuel greenhouse gas emissions by 45% per revenue tonne kilometre by 2035, against a 2019 base year. Additionally, the On-Board Services team is targeting a 10% reduction in service weight per available seat mile (WASM) by 2030, compared to a 2022 base year, impacting both Scope 1 and Scope 2 emissions. Historically, Delta also aimed to reduce net aviation CO2 emissions by 50% by 2050, relative to 2005 levels, for both Scope 1 and Scope 2.
