The main argument for carbon tax is that it will have change people’s behavior. The thing is though that the raising cost of fuel is already doing that. A carbon tax is redundant. Fuel prices are only going to go up and up and that provides people with all the incentive they need to change their behavior. Adding a carbon tax makes such shock therapy all the more painful.
This is no small point. There is no such thing as “revenue neutral” carbon tax. Intentional or not, a carbon tax would shift more of the tax burden onto lower income earners. Students, for example, do not pay much if anything in the way of income taxes. As it is they are facing a double whamming of higher fuel costs, those that have cars anyway, and higher grocery costs. Carbon tax would make things even worse.
