A recent study published in Nature reveals a staggering 46% rise in CO2 emissions from private jets between 2019 and 2023. While business aviation accounts for nearly 2% of all aviation greenhouse gas emissions, this still translates to over 18 million flights in five years, primarily registered in the U.S. Alarmingly, half of these flights covered distances of less than 500 kilometers. The study highlights the notable environmental impact of major events, such as COP28 in Dubai, which saw over 600 private jet flights, and the 2022 World Cup in Qatar, which required more than 1,800 jets.
