Where carbon tax revenues go after they are collected doesn’t really matter, the whole point is to make carbon-emitting more expensive. We’ve ignored the science for decades while the signals of environmental decline abounded, at this point a smart slap right in the wallet looks to be the only thing that’s going to work. Canada’s current carbon tax rate is in the neighbourhood of $30/tonne CO2. In Sweden, where carbon taxation has been in place for three decades, and emissions have dropped steadily and their economy has grown steadily, the current rate is equivalent to $160/tonne. We’re just getting started in Canada.
