I was thinking of the effect of the long distant flights to certain caving expedition areas abroad. Mulu, Mexico, Megahalaya to name a few. Other than not flying so far, or at all, how do you calculate your carbon use and what can you do to offset it? I've seen various companies which charge to offset it for you but that seems a bit, er, like it doesn't really help.
Anyone offer any advice on this subject?
