Arguably depends on the efficiencies - aggregating lots of passengers
through hubs in say the middle east or Turkey might be more efficient
for many journeys.

Which probably depends if one A380 is less polluting than two
777-300ERs, which might not be the case given that the former uses 4
engines and the latter 2.

There's arguably a lot more inefficiency on shorthaul.

The 77W and 38W are both clean and efficient, the latter slightly better
than the former. One single 388 would be much cleaner than two 77Ws. But,
yes, shorthaul is certainly much less efficient.
