So, Pigovian taxes reduce deadweight loss, they do not increase it. Thus the change in the law is one that increases efficiency but reduces equity. And then, this item today will serve as a record that, in 2017, it was not actually so. If the government allocated the permits to firms who did not value them as highly as other firms, the firms could sell the permits to each other so they would end up in the hands of the firms who value them most highly. My own microeconomics text, Quantum Microeconomics,. Pigovian taxes or tradable pollution rights give firms greater incentives to reduce pollution. The only difference would be that the government could make money if it auctioned the permits off, thus allowing it to reduce taxes, which would help reduce the deadweight loss from taxation.
In fact, Pigovian taxes reduce the inefficiency of pollution by reducing the quantity of the good being produced that has pollution as a by-product. The landlord could impose a rule that music could not be played above a certain decibel level. We could question whether this is how people actually do make decisions, or how, according to a particular body of theory, people should make decisions.

Now, this may seem to be a bit like saying that tautologies are tautological -- the reader may be thinking that people would have to be pretty stupid to be unmotivated by motives, or to be inactive in response to something that influences to action.
It shapes what we see, the problems that are identified and the policy suggestions that result. Under command-and-control policies, there is an opportunity cost in terms of the resources that firms must use to reduce pollution. Marginal thinking is to make small adjustments. The market equilibrium level of output is denoted Qmarket and the efficient level of output is denoted Qoptimum. Such desires as behavior do not occur without consideration of cost, risk and uncertainty. Viewed according to this analogy, we might imagine that the issues are really far more complicated, but as general rules of thumb or insights the points may have some value.
And yet, if we investigate history, we find that countries prosper when their policy is aligned with the Magic Formula. Indeed, I believe he is.
