Just how bad are private jets for the environment? Personal planes have significantly higher emissions than other modes of transport. An average journey in one produces CO2 equivalent to driving a petrol car from Paris to Rome 16 times.

On a per-passenger basis, private jets are significantly worse for the environment than standard cars. A private jet can emit up to two tons of CO2​ in a single hour, which is roughly equivalent to what a typical car emits in several months of driving. While a car's total footprint is massive due to the billions of vehicles on the road, a private jet is 5 to 14 times more polluting than a commercial plane and 50 times more polluting than a train. In 2026, the environmental impact of private aviation is a major talking point in climate policy, as just 1% of the population is responsible for 50% of aviation emissions. While a car carries 1-5 people, a jet often carries the same number but uses thousands of gallons of high-carbon kerosene. Even as the industry experiments with Sustainable Aviation Fuel (SAF), the sheer energy density required for flight means that a single short-hop private flight for a luxury traveler has a larger carbon footprint than most people's entire annual commute via car or public transit.
