The amount of energy spent/CO2 generated to transport fuel to the Seychelles by ship can't be more than the amount spent to take it there by plane. Ships generate less than 1/10 the CO2 per tonne-km than aircraft, trucks a bit more but still less than aircraft.

Tankering might not be our main problem but it's an easy to point out environmental "sin" where we place profit/cost over emissions. The main point to make on behalf of airlines is that passengers direct airlines to do everything as cheaply as possible because they mainly go by price when buying tickets. We'd all fly Neos, Maxes, A220s and E2s if only passengers paid a premium to fly on environmentally friendly airplanes. As they don't we don't.
