The Sanders-Boxer carbon tax will be 15 times costlier than letting warming happen

"Standard climatological and economic techniques, combined in an investment appraisal of the proposed Sanders/Boxer carbon dioxide tax (U.S. Senate, 2013), show that even at a zero inter-temporal discount rate the cost of the Bill’s proposed CO2 mitigation if applied worldwide over ten years is 15 times greater than the benefit in the cost of warming-related damage avoided by the intended cut in CO2 emissions, which is here assumed to be – but is in reality unlikely to be – achievable at the stated cost."
