4AIR to support Southwest Airlines with SAF inventory accounting and documentation services

In Massachusetts, 4AIR, the first and only rating system focused on comprehensive sustainability in aviation, announced that it will provide Sustainable Aviation Fuel (SAF) inventory accounting and documentation services for Southwest Airlines. 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 percent 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.
