Abstract. Aviation emission accounting is the key to establishing market measures to control aviation pollutant emissions. Based on the Fuel Percentage Method (FPM), this paper applies the Improved BFFM2-FOA-FPM method to calculate the emissions of six pollutants (CO2, CO, HC, NOx, SO2, and PM2.5) between Chinese and foreign cities from 2014 to 2019, including Landing and Take-off (LTO) emissions and Climb/Cruise/Descent (CCD) emissions. The error rate between the calculated results and the official data is about 2.75 %. The results show that the emissions of six pollutants have changed before and after the proposal of the "Carbon Neutral Growth 2020 " strategy (CNG2020 strategy). Although the total amount has increased, the average emission per ton-kilometre of CO2, CO, HC, NOx, SO2, and PM2.5 had decreased by 17.77 %, 17.26 %, 25.15 %, 14.32 %, 17.77 % and 16.35 %, respectively. The dataset is available from https://doi.org/10.6084/m9.figshare.20071751.v1 (Cui, 2022).

This is an excellent paper. Just one minor issue: the first line of each paragraph should be indented.

This paper a very interesting study applying the Improved BFFM2-FOA-FPM method to calculate the emissions of six pollutants (CO2, CO, HC, NOx, SO2, and PM2.5) between Chinese and foreign cities from 2014 to 2019. It contributes to the literature by filliwng the gap in the effect of aviation on the environment. The paper is written well and the discuss is highly valid. The following minor comments can be considered to improve the paper:
- Please further highlight the significance of this paper in the Abstract.
- All figures can be further improved to be more precise.
- Authors state the data came from VariFlight and did not mention the exact data types. A more detailed introduction of the data should be added.
