That is a fair criticism of this kind of thing in general, but in this particular case I wanted to combine the Pigovian "tax the bads" idea with the more modern idea of a feebate, which is intentionally revenue neutral (to the Government) in that the fees levied on the "bad" side of the ledger go to pay subsidies or other incentives on the "good" side of the ledger.
