Japan aims to reduce CO2 emissions by about 10% in the aviation sector through flight path shortening and other improvements in flight operation methods. However, it has not been quantitatively clarified how much reduction can actually be expected. In addition, considering CO2 emissions, it is necessary to select the optimal aircraft and number of flights compared to the current situation. Therefore, the purpose of this study was to estimate the CO2 reduction potential by shortening flight routes and selecting aircraft and flight numbers, and to analyze the effects on passengers and airlines. As a result, the CO2 reduction potential of shortening flight routes and selecting aircraft and number of flights was quantitatively determined for the domestic airline network. The impact of these reduction measures on passengers and airlines was compared, and it was clarified that high-demand routes have the potential to reduce CO2 emissions by selecting aircraft and number of flights.
