I still can’t wrap my head around the physics. Commercial jets weigh more than private jets and carry much more people (which also contributes to the extra weight)
Doesn’t that mean the plane would have to do extra work to move around, and thus consume more fuel as an energy source?
Shouldn’t that make them emit more gases as end products of combustion?

on a one to one comparison, commercial jets emit more greenhouse gasses. just like a bus emits more greenhouse gasses than a car. but the point in all those “green comparisons” is that you can fit 50 people on a bus and 4 on a car (or 300 on a 747 vs 15 on a bizjet). so in total the greenhouse gas emitted per person is much less if all those 50 people use a bus instead of 25 (or 50 cars). same for private jets vs commercial jets. per person, it’s less greenhouse gasses emitted (assuming the plane is full).
