They absolutely do produce soot, and the production of hydrogen is horrible for the environment as well.
Methane is not so bad. Still produces soot but not nearly as bad.
Space X uses kerosene and liquid oxygen.
Virgin galactic uses HTPB and liquid nitrous oxide
Blue origin uses liquefied natural gas.
I do hope for alternatives for commercial use but am also very hesitant to support en made space tourism at the moment.
But you’re correct in that hydrogen and methane are cleaner that what is used now

How? Hydrogen and Oxygen yield water. Where does the soot come from?
