National emissions inventory and future trends in greenhouse gases and other air pollutants from civil airports in China.

ABSTRACT: Civil aviation is an important source of air pollutants, but this field has received insufficient attention in China. Based on the standard emissions model of the International Civil Aviation Organization (ICAO) and actual flight information from 241 airports, this study estimated a comprehensive emissions inventory for 2010-2020 by considering the impacts of mixing layer height. The results showed that annual pollutant emissions rapidly trended upward along with population and economic growth; however, the emissions decreased owing to the impacts of the COVID-19 pandemic. In 2020, the emissions of carbon monoxide (CO), nitrogen oxides (NO_X), particulate matter (PM), methane (CH₄), nitrous oxide (N₂O), carbon dioxide (CO₂), and water vapor (H
