Frome some people who are trying to defend flying. I’ve assumed their numbers make at least some semblance of sense for their argument.
But true, it’s too high. It’s more like, 10 to 15 percent of the greenhouse gas emissions from tranportation come from aviation. Which is still significant, but indeed more like 2-ish % of all greenhouse gas emissions. Still, it’s one of the sources easiest to mitigate. Agriculture causes over a quarter of all emissions, so that would be the most important thing to look into.
But also, it’s common to only look at the amount of carbon dioxide coming from the exhaust, while planes are problematic largely because they happen to travel at the altitude where their emissions hurt the most. As almost any sources I can find put the aviation’s share around 10 to 15 % of transportation’s emissions, and it has been so commonplace to ignore the altitude where planes travel, maybe the real number is more like 3 to 5 percent or so?
Where the hell did you get that absurd number from?
