Efficiency and SAF key to cutting aviation emissions

Rate of efficiency improvements must be doubled while SAF production must grow fivefold under a net-zero scenario

Greater use of sustainable aviation fuels (SAFs) and improved aircraft fuel efficiency will be the most important factors in reducing aviation sector emissions under two scenarios developed by the Mission Possible Partnership (MPP)—an alliance of climate research groups and private companies—that are consistent with a global net zero by 2050 pathway. Under both scenarios, annual fuel efficiency gains are doubled compared with historical gains and SAF production capacity is ramped up from the current 5.5mn t/yr to 40-50mn t/yr by 2030 and 300-370mn t/yr by 2050. “This transition strategy outlines plans and projects that are high on the agenda of ambitious companies, including the ‘nuts and bo
