GHG Emissions Inventory

next.svg
In the GHG emissions inventory below, CO2e numbers cover all GHG emissions as carbon dioxide equivalents. CO2 numbers only include carbon dioxide.
As part of our SBTi target-setting process, we assessed our Scope 3 emissions using the GHG Protocol Corporate Value Chain Reporting Standard. In 2022 we have expanded our disclosures around Scope 3 emissions to include additional categories, and we expect future work to focus on continually adding Scope 3 categories identified in the GHG Protocol.
  • Our GHG inventory covers emissions from all operations under Delta’s operational control: Delta, Endeavor, Delta Vacations, Delta Material Services and Delta Flight Products.
  • The emissions reported for 2019–2022 were calculated and verified using the GHG Protocol, which aligns with the SBTi framework.

1 Totals may not sum due to rounding. 2 Scope 3, Category 3 calculations use primary data, and beginning in 2022, Delta calculated Scope 3, Categories 1, 2 and 4 using secondary, spend data.
We have verified our GHG emissions data in accordance with the GHG Protocol. Our 2022 verified report is available in the Appendix.
SCOPE 1
Consists of all GHG emissions generated as part of the operation of Delta’s air transportation business: emissions from jet fuel and SAF consumed by Delta mainline aircraft, wholly owned subsidiaries, plus GHG emissions from ground support equipment and other ground operations and chemical use.
SCOPE 2
Consists of GHG emissions resulting from the generation of electricity, heat or steam purchased by Delta in owned and leased facilities, such as airport spaces.
SCOPE 3
In 2022, consists of our purchased goods and services, capital goods and upstream transportation and distribution (Categories 1, 2 and 4) and all GHG emissions from jet fuel from Delta Connection carriers that we do not wholly own and emissions from jet fuel and SAF production from our suppliers, including Monroe.
To align with SBTi guidance, from 2021 forward, we are including upstream well-to-tank emissions for our jet fuel in our Scope 3 emissions to reflect our fuel’s full life cycle emissions. In 2022, upstream jet fuel GHG emissions totaled 6,186,729 mT CO2e.3
3 Beginning with this report and going forward, we will include upstream well-to-tank emissions from our mainline jet fuel in our totals going back to 2019.
