A smart friend recommends this article by Yale economist Bill Nordhaus
. The Pigou Club endorses the conclusion:
The need for taxes on energy externalities such as carbon emissions is central to our ability to reduce the harmful side effects of economic growth. It is striking how the political dialogue in the US has ignored a policy that has so many desirable features. Perhaps, in the near future, faced with the deadline of a dire economic situation, negotiators will formulate such a policy. It would generate substantial revenues while bringing so many long-run economic and environmental benefits. Simply put, externality taxes are the best fiscal instrument to employ at this time, in this country, and given the fiscal constraints faced by the US.
