I'm not really stumping for the carbon tax here, it's mostly just a thought experiment on the relative significance of pricing carbon. I have to add though, while carbon taxes would have challenges to implement, adding a carbon tax to fuel specifically is not hard to measure at all! We know exactly how much carbon is in the fuel. A $40/ton carbon tax means +$0.36 per gallon of gasoline. P.S. The US federal fuel tax ($0.18) was last increased in 1993, and was not indexed to inflation.
