A conservative scenario assumes continued moderate technological developments in aircraft and flight management. A variant with a 40 percent admixture of Sustainable Aviation Fuels (SAFs) was also considered. In this case, climate-relevant emissions continue to rise due to the forecast growth in air traffic, despite efficiency improvements. In addition, a progressive scenario with new technologies, processes and comprehensive use of SAFs with an admixture ratio of 80 percent points the way to reversing the trend in global carbon dioxide emissions from air transport despite traffic growth. For comparison, a 'Do Nothing' scenario is also shown, which reflects the evolution of emissions without further technical progress.
