This is an impractical idea from the get-go. There are numerous instances of 'green credits' and 'trading or offsetting credits". This is a sham which does nothing for the environment, and allows big polluters to continue big pollution, to say nothing of the possibility of outright fraud and cheating.

A better idea is that each of us take individual responsibility for the energy we use (and often waste), and force industry to actually reduce (not offset) their pollution. Force does not necessarily mean government action, but could be citizen action such as product boycotts.
