Scope 3 emissions were approximately 22.86 billion kg CO2e, with significant contributions from investments (about 7.18 billion kg CO2e) and fuel and energy-related activities (about 10.03 billion kg CO2e).

Looking back, Delta's total emissions were approximately 59.51 billion kg CO2e in 2024 and approximately 54.97 billion kg CO2e in 2023.

Delta is committed to achieving 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. The company has set Science Based Targets initiative (SBTi) approved goals, committing to reduce well-to-wake Scope 1 and 3 jet fuel greenhouse gas emissions by 45% per revenue tonne kilometre by 2035, from a 2019 base year. Additionally, Delta aims for a 10% reduction in service weight per available seat mile (WASM) by 2030, compared to a 2022 base year, for both Scope 1 and Scope 2. 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.
