I don't know, but I have a hard time buying the private jets as the problem. How many of them are flying, in comparison to normal airliners?
It's like saying that the 3 Ferraris in the city are the problem, not the million Volkswagens (or whatever).
Heck, if this helps those folks focus on the problem at hand, I'd rather have them fly private than go through the stress of flying regular (which in my view is mostly horrible).
They are not a big problem per se, but the message that sends is pretty bad. I think many people are worried about "green" policies exacerbating inequality, with the rich flying and doing what they want while the poor aren't allowed cars.
I agree w/ you about the message they send (ie. it's pretty much hypocrisy).
But the inequalities were already there. It's not like if they stop flying private, they'll all of a sudden be less wealthy. At least they spend their money, instead of hoarding blindly (not that flying private changes this by much, I have to admit).
The inequalities may be there, but even rather poor people (in the US) are quite rich in an absolute sense, at the moment. Radical green policies would cause real, tangible changes to people's lives; if you actually wanted to reach realistic climate targets, many people wouldn't have cars due to carbon taxes, electricity costs would be much higher, etc.
Someone indirectly advocating for such things while flying in a private jet is a pretty bad look. It reminds me of a medieval king gorging himself on food while telling the population to slim down.
It's a matter of perception. It'd be like having an obese personal trainer lecturing you on proper diet and exercise. Everything they're saying might be true, but at best it comes off as hypocritical, at worst that they're getting paid to lie to you.
