A few notes:
SpaceX is working on ways to mitigate the effect of greenhouse gases produced by its launches.
Check out The Everyday Astronaut on YT for an analysis of the relative amounts of pollution caused by all rocket launches versus other sources.
Check out Engineering Explained for whether you should trade in your car to save the planet.
SpaceX isn’t in the space tourism game, though they will certainly take the money, if it can be profitable. At least you get real space.
Of course, you could have found all of that yourself, but I’m guessing you just wanted to puff out your chest a bit. So be it, but Musk is on a different planet than the other players in the private space game. And at some point, the last sentence may become a literal fact.
