The Impact of Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) on International Aviation CO2 Emissions East Carolina University, United States of America This paper examines the effects of CORSIA on international aviation CO2 emissions, using novel flight-level emissions data estimated from actual fuel usage. Compared to the baseline year of 2019, when CORSIA became effective in 2024, the time series event study results show that flight-level CO2 emissions on the routes subject to compliance reduced by 7.85 tonnes (13.9%), which is equivalent to removing about two passenger vehicles for a year, indicating airlines’ efforts to curb CO2 emissions. Compliance by airlines based in CORSIA member states yields a positive spillover effect on the non-CORSIA-applicable routes they operate on. Specifically, Difference-in-Differences (DID) results show that, compared with non-CORSIA-based peers, CORSIA-based airlines’ flight-level CO2 emissions are 3.71 tonnes (6%) lower, owing to having more aircraft equipped with fuel-efficiency devices and a younger fleet. Specifically, for every 1000 aircraft, CORSIA-based airlines have 66 more aircraft installed with fuel-efficiency devices. | |
