An idea via global media.

The Air belongs to us all. We are send carbon trading credits. We can then sell the credits (or keep 'em). The money from the sale goes into the consumers pocket. If you have a low footpint - you make money.

Call me cynical but it sounds like a licence to pollute. Since the government would decide the amount of "certificates" issued and over time this would certainly increase, it just sounds like another wealth transfer scheme. If you're talking some kind of science based quota scheme I have even less faith in the ability of governments to manage it, Canadian cod anyone?
