I can’t say I’m surprised; it’s always seemed like those to blame for aviation-related emissions are not really ordinary people who jet off for the occasional holiday,1 but business travellers who fly multiple times a week (and as this article says, especially those with private planes).
Of course, I think wherever possible, high-speed trains should be used instead of planes, being considerably less polluting as well as way more pleasant to travel on. Australia could eliminate the need for sooooo much flying if we had a high-speed line connecting every city from Adelaide around to Brisbane. But not everywhere is easily accessible without flying (think about islands, or relatively isolated cities like Perth…). Sometimes I see “environmentalists” online basically arguing to abolish aviation, but it’s not really a huge problem if people occasionally take a long-haul flight, or a flight to one of these isolated/island places. The bulk of the emissions are from frequent flyers, who are predominantly concentrated on short-haul routes like Melbourne-Sydney that could easily be replaced with trains.
Although note, the article also says that only 11% of the world’s population flew at all in 2018 (as a representative, recent pre-Covid year), so this definition of “ordinary people” is definitely skewed towards the “ordinary people” of relatively affluent, developed countries. But still. ↩︎
