Where does it state that the CO2 is concentrated in Europe? It shows CO2 in produced in general and obviously it doesnt always matter where the CO2 is produced as it can the potential to affect the ecosystem at the other end of the planet.
Of course CO2 rejected in the atmosphere affects everybody on Earth.
But how can you compare intra-European flights and CO2 rejection with extra-European flights and CO2 rejection, and then peg them against each other?
Well if I understood correctly your question the answer is quite simple.
Eurocontrol investigates flights originating from European airports and their impact on CO2. Destination is irrelevant.
You can have plenty of flights departing from a European airport and arriving at a non European one of less than 500km so those would count towards the <500 km total.
Similarly you can have a intra-European flight of >4000km.
Again destination does not matter, rather than number of flights.
The correct debate in my eyes wouldnt be intra-European vs non intra-European but km per passenger flown vs emissions but the >4000km flights would be leading that metric as well but maybe not by that much though.
Long-haul flights duration happen disproportionally outside of the European airspace than 500km-or-less flight, when both originate and/or end in Europe.
So, you cannot compare what's not comparable.
If we were to compare the same criterion on a world-wide basis, then it would make sense; and it would give a clearer picture where progress should be made.
Like you mentioned, regardless where CO2 is generated, it affects us all.
EDIT: what Europe is doing right now towards flights goes counter to what this "study" concludes. Right now, the push is to reduce short flights and replace them with ground transportation; if the study was correct, then why do that since they generate less CO2?
