Just 1% of people are responsible for half of all toxic emissions from flying.
Fossil fueled cars aren’t going to get that much more efficient in the foreseeable future, especially since manufacturers know they are a dead horse.
So what do you propose for that sector? Banning driving? And that’s then easier than banning private flying, despite far more people relying on it every day, it being far more decentralized and far harder to regulate for that reason? Globally, at that? I mean of course we should improve public transit to make it a better alternative, but that’s an equally monumental task that will take decades in most places.
Air travel is definitely a lower hanging fruit as for the majority of people it’s a luxury, not a necessity.
You do know that electric cars exist, right? Replacing gas powered cars, trucks, and semis would have a far more significant impact with less inconvenience and change required than it would to ban commercial air travel even partially. You say it’s a luxury but companies, families, and governments rely on it.
