    I'm a huge believer in space development, and in contests to facilitate it. I also agree that we need cheap access to low-earth orbit.

    But I do believe that Branson is being a hypocrite about it.  On a per-capita basis, space tourism probably spews MUCH more carbon than any jumbo jet.

    Learn about Centrist Economics, learn about Robert Rubin's Hamilton Project.

      I am looking for it right now, and there was a study that found that, on a per capita basis, space tourism would be quite green.

      when I find it, I'll provide the link

      It will take years (more likely decades) for space tourism (aka rocket flights) to approach anywhere close to flight rates like commercial jetliners.  

      Even on a per-capita (I assume you mean on a per-flight) basis, the rocket runs for minutes versus hours on a jet flight.

      If the fuels are chosen correctly (Liquid Hydrogen and Liquid Oxygen) CO2 is not even a byproduct of rocket flight.

      Lots of more effective places to work to fix Climate Change in my opinion.
