Carbon Taxation Update
An interesting enquiry emerged from roughly give-and-take surrounding my final carbon taxation post. How big volition the taxation be? The missive of the alphabet says $40 a ton, precisely hence rising. But how far? And inwards response to what question?
It occurs to me that the 2 obvious targets atomic number 82 to radically unlike answers.
1) The social cost of carbon. This is what economists commonly recollect of equally the appropriate Pigouvian tax. In enterprise to pollute, yous pay the cost yous impose on others past times your pollution.
Even the worst-case scenarios instantly set the cost of carbon emissions at 10% of gross domestic product inwards the twelvemonth 2100. Discount that back, split upwards past times all the carbon emitted betwixt instantly together with then, and, you're going to larn a pretty small-scale tax.
2) Temperature or quantitative guidelines. Or, "whatever it takes to terminate the global temperature from ascent to a greater extent than than 1.5 degrees C." Such a taxation has to live high plenty to basically terminate us from using fossil fuels. It would live radically higher, together with impose economic costs far higher than 10% of GDP.
When yous laid upwards a finish of a quantity amongst no attached price, the cost tin larn pretty high.
I encounter instantly roughly of the dorsum together with forth chatter. Anti-carbon types warn that whatsoever taxation "won't live enough." Now I know what they mean.
So who sets the tax, together with on what basis, are of import issues we're all fudging over.
Of course, a cynic would stimulate got the stance that the taxation volition live laid upwards to
3) Maximize authorities revenue.
Given the behavioral elasticities, that is probable to live a skilful bargain less than #2, equally to high a taxation volition chop-chop erode the taxation base.
PS: to my may CO2-is-not-a-problem commenters. If (or mayhap when) it's all proved to live a hoax, a carbon taxation is a lot easier to undo than the choice regulatory approach!
