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 (Cui, 2022).

Short summary
This paper calculates the emissions of six kinds of emissions from China’s external routes from 2014 to 2019, enriching the existing database. This paper applies the Improved BFFM2-FOA-FPM method and ICAO method to calculate the emissions, which can combine CO2 and non-CO2 emissions calculations and calculate the aircraft types' emission intensity.
