We've a similar program already in place out here in CaCaLand. A generator can obtain carbon credits -- kind of a get out of jail free card. So, they supply their "green" energy with crappola tech like wind turbines or solar. They then turn round and use a credit to buy additional dirty energy from out of state, even from a coal plant. But, because a carbon credit was used that dirty energy is classified, officially, as green.
This is how companies can get themselves labeled as green.
