One can believe in the reality of a problem and rationalize one's own contribution.
I'm a prime example - I don't need to run a vehicle, I could take the bus to work. Of course, I'd spend two more hours every day commuting, get behind on my sleep, and my health and work performance would suffer. It might be the best thing I could do for the climate. But I'm convinced enough that I'm on the side of the better angels that I do this harm to my fellow organisms in hopes it will make me more effective where it counts.
If I was an Oligarch or world leader commuting to the biggest professional convention of the year, my considerations - and I daresay my decision - would be identical, just on a larger scale.
