A private jet emits significantly more CO2 per hour than a car does in an entire year. On average, a light private jet emits roughly 2 metric tons of CO2 per hour of flight. In comparison, the average passenger car emits about 4.6 metric tons of CO2 per year. This means just 2.3 hours in a private jet equals a full year of driving for the average person. When looking at "per-passenger" impact, the gap widens further because private jets often fly with only 2–4 people. A flight from New York to Washington D.C. (roughly 1 hour) would emit more carbon per person than a car-pooling group making the same trip ten times over.
