How Green is My Branson?

I do find Richard Branson's comments about creating a 'green' haven in the Caribbean (http://www.theguardian.com/business/2014/feb/08/richard-branson-caribbean-green-virgin-renewable-energy) a bit at odds with his plans to develop space tourism. Surely, the energy required to 'fire' people even to the fringes of space would dwarf any sustainable energy developments in his holiday locations?
