Southwest Airlines to Document SAF Use  

Southwest Airlines will provide Sustainable Aviation Fuel (SAF) inventory accounting and documentation services through 4AIR, a rating system focused on comprehensive sustainability in aviation.

In October 2021, the carrier announced a series of near-term goals, actions, and initiatives in support of a 10-year plan to maintain carbon neutrality to 2019 levels while continuing to grow its operations. This includes a goal of replacing 10% of its total jet fuel consumption with sustainable aviation fuel (SAF) by 2030. SAF is a key strategy to address the carbon emissions generated by the aviation industry associated with climate change.

Under the agreement, 4AIR will support Southwest with allocating and documenting certain Scope 3 emission reduction rights arising from Southwest’s use of SAF for corporate clients participating in its SAF Beta Program. These clients purchase Scope 3 emission reduction rights arising from Southwest’s use of SAF, which contributes to reducing the premium of SAF over conventional jet fuel and helps send demand signals to the market.

“We are excited to partner with 4AIR to offer corporate Customers participating in our SAF Beta Program with independently verified assurance for the Scope 3 emission reduction rights associated with their support of expanding SAF in our operations,” said Helen Giles, Southwest Airlines’ Director of Environmental Sustainability in a statement. “We have processes in place to track emission-reduction rights for our corporate partners in the program, and we are proud to add this additional layer to verify that emission-reduction rights purchased have been correctly accounted for.”
