Walsh described SAF as the "only" current solution to significantly reduce emissions from long haul flight, she said: "For aviation to reach its net zero carbon emissions goals by 2050, the SAF industry will need to scale significantly." "While the SAF supply is small compared with the airline's overall fuel use, it is nine times the size of Air New Zealand's first shipment of SAF from Neste in 2022 and demonstrates growing cooperation between two like-minded organisations to advance the supply and use of SAF."
