"carbon offset" is big business in the aviation world although I feel it's just virtue signalling.

If they were serious about aiming for "carbon neutral" the plane would never take off in the first place!

I admit this is a very simplistic view and likely I just don't understand the bigger picture about economics of carbon offsetting.

Aviation is one of the easiest cases because the amount of fuel burned is tracked and ~100% of the carbon in the fuel becomes CO2. Since there's currently no good alternative to hydrocarbon fuel, it's also a good case for biofuel or carbon capture (not offsets which are mostly fake).
