Researchers Calculate the Cost of CO2 Emissions, Call for Carbon Tax
Brito and Curl argue that there are three important unresolved questions in the current debate on the reduction of carbon dioxide emissions: "First, what is the range of prices on carbon dioxide emissions that will be necessary to achieve the desired reductions? Second, should electrical generators and transport fuels be regulated jointly or separately? Third, should the restrictions be in the form of a quantity limit such as cap and trade or in the form of a carbon tax?"... The authors noted that the efficiency of coal generators is very concentrated. For instance, "at current prices for fuels, a carbon price of approximately $30/ metric ton (MT) will shut down 10 percent of coal generator capacity," they wrote. "An additional increase of $15 -- resulting in a carbon dioxide price of $45/MT -- will shut down 90 percent of coal generator capacity."... As a result of the risk of high volatility, the authors back a carbon tax to assist the transition from coal to natural gas. They also assert "it is possible to decouple the pricing of allocations for transportation fuel from the allocations for the production of electricity," because the rise in carbon prices needed to effect the shift in electricity generation would have very little impact on transportation fuels.
