THIS. So many people claim to care about improving things, but then put exactly zero effort into identifying how to best go about that improvement. As a result, they end up focusing entirely on superficial things, which inevitably comes down to asking people to make arbitrary sacrifices or endure meaningless pain in order to "demonstrate" that they care.
The most annoying example in recent memory was the drought in California, during which I was actually chastised by multiple people for… flushing the toilet.
It turns out that the universe is governed by physical laws, and those who care the most about effecting change in the universe will therefore take the time to do the analysis and the math to find out how they can do so effectively. Everyone else is just playing holier-than-thou, or engaging in the millennia-old game of finding some reason to demonize people who are are richer than them.
At some point you have to ask yourself whether you care about appearances or results.
spoiler: it's not them.
The majority of bizjet trips are between airports that don't have direct service. So alternative travel would involve connections with multiple take-offs, which are much more polluting than sitting at cruising altitude.
I highly doubt that non-direct flights on airliners pollute more per passenger than a direct flight on a small jet that isn't necessarily full.
All the small categories of climate sins can be trivialized when considered one by one, but they make up the whole.
Effectively anything other than biking or hiking there would be enough grounds for pointing and screaming "HYPOCRITES!".
And then they'll congratulate themselves for being so visionary and good.
There are two possibilities:
a) Private Jets are an important source of pollution. Then we should complain about private jets all the time, not just when we want to smear the people who use them to travel to climate talks.
b) Or private Jets are not really that much of an issue on a global scale, and we should focus on whatever is actually discussed at Davos, rather than complain about how people get there.
The article makes no effort to quantify, or put into relation, the actual impact of people travelling with private jets, so I really don't see what it brings to the table, except triggering a bit of outrage here and there.
