4、 GREENHOUSE GAS POLLUTION FROM PRIVATE JETS,2023EXECUTIVE SUMMARYThe aviation industry,including commercial,private,and military aircraft,emits about 1 billion tonnes of carbon dioxide(CO)annually,making it the seventh-largest source of CO if considered a country.Without significant action,emissions

5、 from international aviation could double or even triple by 2050,reaching up to 1,800 million tonnes(Mt),according to the Climate Action Tracker(2024).While there are several high-fidelity emission inventories for commercial aviation,data on greenhouse gas(GHG)and air pollution from general aviation

6、including nitrogen oxides(NOX)and fine particulate matter(PM2.5),which impact air quality and human healthremain limited.Private jets were responsible for about 2%4%of total annual GHG emissions from aviation in 20132023.Better data on the magnitude and distribution of private jet pollution could he
