This is from a comment posted at the BBC web site:
Has it ocurred to anyone that the carbon trading schemes now in play could eventually evolve into a proxy global currency and eventually a real one? The dollar will debase down to zero in a few years and we need a new global reserve currency.
A carbon currency credit backed by a negative value (pollution).
Banks, goverments, politicians and climate financiers will make hundreds of billions, maybe trillions out of it.
Call me a sceptic - watch that space!
