The aviation sector has been one of the sectors most affected by the various policy responsesimplemented to control the COVID-19 pandemic. Stay-at-home orders as well as national andinternational travel restrictions/controls implemented during the pandemic have had significanteconomic impacts on the sector, as they are the main determinants of the decline in demand forair transportation services. Additionally, global CO2 emissions from air transportation havefallen significantly during this period. In this study, firstly, the validity of the club convergencehypothesis for CO2 emissions of the aviation sector in 138 countries was tested using monthlydata for the period 2020-2022. Then, the effects of the control and restriction policiesimplemented during the COVID-19 pandemic on the CO2 emissions of the aviation sector weretried to be revealed for all countries included in the analysis and also for the convergence clubsby using panel data analysis methods. According to the findings, although the hypothesis thataviation sector CO2 emissions converge is rejected for all 138 countries included in the analysis,four potential convergence clubs were identified. Panel data analysis results indicate that theimpacts of policy responses to the COVID-19 pandemic, such as stay-at-home orders andnational and international travel controls/restrictions, on aviation sector CO2 emissions differsignificantly for different convergence clubs.
