This is problematic. The more you tax flying, the more you make it only a rich person's activity.
Why only international flights? Domestic flights produce about the same amount of emissions, and are easier to substitute with something else, e.g. train journeys.
The other problem with aviation is that we don't have any tech that can really replace it, whereas we have the tech now to replace most other sources of emissions. My view is that if we can get all the sources of emissions down, then we can probably live with the 2% or so of emissions from aviation until we have the tech to replace it.

This is something I'd support. Reducing red meat consumption would likely improve health, the environment, animal welfare, and other things as well as reducing emissions. However, very difficult to achieve politically.

We need a multi-pronged approach to simultaneously reduce emissions on all fronts. We can't just ignore 2% of global emissions if we're serious about tackling the problem.

Why is that a problem? Climbing the Mount Everest, Joining a Country Club, or flying into space is also a rich person's activity - is that a problem too?
> Why only international flights
AFAIK some countries already tax domestic flights. And if they don't, that's easy to achieve. Taxing international flights is harder, because there'll always be a few countries that won't agree.
> However, very difficult to achieve politically.
Yes. But "difficult to achieve politically" is strange: because the only hurdle to take is not a 'real' hurdle. Not 'real' as most engineering, or economic hurdles are. It's not a matter of money, funds, scientific breakthroughs or such, it's mere a matter of willingness to change. Which, it appears, is one of the hardest hurdles to take.
And yes: I agree we should not leave any percent improvement on the table. But I remain with my point that money and effort that we can spend only once, should not go to changing the habits, cultutre and lifestyle of 1/4th of the worlds' population for a meagre 2% win, but to changing the habits, culture and lifestyle of another part of the population can get us a 15% win.
Ideally we'd be able to spend that effort and money twice. For a total 17% win. But as long as we cannot do that, let's spend it on where it gets the biggest results.
