The global aviation sector had an emissions intensity of *** grams of carbon dioxide per revenue passenger kilometer (gCO₂/RPK) in 2023. Under a business-as-usual scenario, the aviation sector's emissions intensity would rise *** percent by 2050, relative to 2023 levels, to *** gCO₂/RPK. Under a net zero scenario, the emissions intensity of the aviation sector would decrease to approximately 130 gCO₂/RPK by 2030, before dropping to less than 30 gCO₂/RPK by mid-century.
