@PupWrafie @hongminhee that's still under half of building heat/light/cooling. About a quarter of ground transport. It's on a par with steel and cement. There's a lot more far larger gains to be made before we worry about flying. Esp as for anything across an ocean, we have no viable alternative. And for many continental journeys the alternatives aren't great. I can't run night trains, I can't build high speed rail.
Apr 7, 2026, 6:42 PM@quixoticgeek @hongminhee yet it's one of the things that can get worse fast "Flying is one of the most carbon-intensive activities — yet it contributes just 2.5% of the world’s carbon emissions. How does this add up? Well, almost everyone in the world does not fly. Studies estimate that just 10% of the world flies in most years.1 But as incomes rise, this will change."
See the whole article I quoted.
@PupWrafie @hongminhee a lot more of us heat/cool our homes, or own cars, maybe those are areas we should focus on instead ?
And I say this as someone who's made a single flight in 20+ years.
