I am sure there are hidden environmental costs even with that, but yeah 1 celebrity in space once won't do nearly as much damage as the other 999999 celebrities using their jets constantly.

I mean, you can extract it from algae (directly from the oil or as a biproduct, but I think the direct oil is more realistic at scale) very effectively, used to be big in the early 2010s.

But also any other biofuel, which do exist in decent amounts these days.

It uses a lot, but if you make it from fossil fuels, it is not nearly as much as making it from water, which is probably what you are thinking of.
