In 2024, Delta Air Lines reported 23,119,882 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2024 disclosure of Delta Air Lines includes a breakdown across 8 of the 15 Scope 3 categories defined by the GHG Protocol, up from 7 in 2023, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2024, Delta Air Lines reported total Scope 3 emissions of 23,119,882 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 71.37% of these emissions originated from upstream activities such as purchased goods and capital goods, while 28.63% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2019, Delta Air Lines's Scope 3 emissions have increased by 111.2%, reflecting a rising long-term trend in Scope 3 emissions over time.a
Compared to the previous year (2023), Delta Air Lines's Scope 3 emissions increased by 15.03%, suggesting that the company faced challenges in reducing emissions across its value chain.a
In 2024, Delta Air Lines reported emissions for 8 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This partial disclosure allows for some insight into the company's indirect impacts.
In 2024, the largest contributors to Delta Air Lines's Scope 3 emissions were:a
In 2024, Delta Air Lines reported Scope 1 greenhouse gas (GHG) emissions of 37,284,766 tCO₂e and total revenues of USD 61,643 millions. This translates into an emissions intensity of 604.85 tCO₂e per millions USD.a
In 2024, Delta Air Lines reported a Scope 1 emissions intensity of 604.85 tCO₂e per millions USD. Compared to the peer group median of 830.79, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2024, Delta Air Lines ranked 6 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Delta Air Lines is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2024, Delta Air Lines reported a total carbon footprint of 60,570,032 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 7.82% increase compared to 2023, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Delta Air Lines's total carbon footprint was Scope 1 emissions, accounting for 61.56% of the company's total carbon footprint, followed by Scope 3 emissions at 38.17%.a
