Abstract:For the Guangdong-Hong Kong-Macao Greater Bay Area airport group in the 2018~2019 shipping season, the aircraft main engine emission factor and the weighted airport emission factor in the region were obtained through the correction of the height of the mixed atmosphere to the climb/approach time and the actual taxi time. Meanwhile, considering the emissions of aircraft auxiliary power units, the inventory of aircraft Land take-off (LTO) pollution emissions was listed. The results showed that pollutant emission factors of airports in the region were significantly different, mainly due to the correction of actual operating time and the proportion of different aircraft types in each airport. The mean values of NOx, CO, HC, SO2 and PM weighted emission factors in the region were 17.58, 8.60, 0.79, 1.37 and 0.15kg respectively. The emissions were 15327.4, 8066.7, 728.4, 1186.1, and 121.9t respectively, most of which were from the main engine emissions of the aircraft. During the research, NOx emissions showed a high trend in summer and autumn and low in winter and spring, while changes of CO, HC, SO2 and PM emissions were relatively flat. The order of pollutant emissions from the airports in the area was relatively consistent, with Hong Kong and Guangzhou Baiyun ranking the top two. Among all models, NOx and SO2 mainly came from A320 emissions, accounting for 19.5% and 17.1% respectively; the models with the largest CO and HC emissions were A321, which were 25.4% and 27.2% respectively; the model with the largest proportion of PM emissions is B738, accounting for about 23.1%.
