Pathways towards 90% decarbonization of aviation by 2050

Nature Climate Change, Published online: 29 September 2022; doi:10.1038/s41558-022-01486-3

Demand for aviation will increase by 2–3-fold by 2050. Nonetheless, 90% decarbonization compared with 2019 can be achieved by continued efficiency gains in aircraft and operations, and by the use of ultra-green fuels derived from biomass or clean electricity. Achieving this decarbonization goal will require an increase in airfares of up to approximately 15%.
