摘要：
In pursuing global carbon neutrality, understanding the potential roles of decarbonization tech-nologies in air transport, such as electric aircraft, hydrogen-powered aircraft, bio-jet fuel and synthetic fuel in the global energy system, is important. This study systematically and quantita-tively analyzed the impacts of these decarbonization technologies on the global energy system under the Paris temperature goals. The model analysis showed that the introduction of electric aircraft, hydrogen-powered aircraft and synthetic fuel into the aviation sector would contribute to the cost-effective achievement of emissions reductions in line with Paris goals. For achieving 2 ???C with 66 % probability, the introduction of electric-and hydrogen-powered aircraft, and synthetic fuel would decrease mitigation costs by 2,743 billion USD/yr and 135 billion USD/yr in 2100, respectively. However, there are no feasible solutions without these three technologies under assumed conditions. This study illustrates the crucial role of these technologies in long-term decarbonizing pathways, affecting global petroleum consumption. <comment>Superscript/Subscript Available</comment
