This first comprehensive emissions inventory shows that one private jet emits as much climate pollution as 177 cars or nine heavy-duty trucks.
(San Francisco/Berlin), 27 June 2025 —  A groundbreaking new study from the International Council on Clean Transportation (ICCT) estimates that private jets produced up to 19.5 million tonnes of greenhouse gas (GHG) emissions in 2023, a 25% increase over the past decade and accounting for nearly 4% of all civil aviation emissions at their post-COVID peak. This amount represents more greenhouse gases than from all flights, including commercial airliners, departing London Heathrow Airport in 2023.
The report fills a critical gap in understanding aviation’s environmental impact by providing the first detailed global mapping of private jet air and climate pollution. By combining global flight trajectory (ADS-B) data with publicly available emissions models, the ICCT’s research team spatially allocated more than 90% of private jet activity and emissions to airports and countries.
