Fewer passengers: Private jets are designed to carry a small number of people, often just a handful. Passenger planes, on the other hand, can carry hundreds of passengers. This means the emissions from a private jet are spread out among far fewer people.
More frequent takeoffs and landings: Private jets often take off and land from smaller airports, which can mean shorter flights. Takeoff and landing are the most fuel-intensive parts of a flight, so these short trips contribute disproportionately to a private jet's CO2 emissions.

Studies estimate that private jets emit 5 to 14 times more CO2 per passenger compared to commercial airlines [Transport & Environment].

Private planes emit significantly more CO2 than passenger planes per passenger.

Read my message again, I never said they don't. They still represent an insignificant proportion of air traffic emissions.
