> Canada just refunds people whatever they collect in carbon taxes at the end of the year This is a very clever system which I have to admit sounds like a great idea, I was talking about things like carbon credit markets. > Anyone who thinks you should emit less carbon understands that making carbon more expensive This is not the case, it's likely (and to the point of OP) that making carbon more expensive in location A just acts as an indirect subsidy of carbon emissions in location C. In other words, if you make 1 KG of carbon more in location A, that will often make it economical to perform the same work in location C (still releasing at least 1KG of carbon) and then ship the result back to A releasing another KG of carbon. Worse, the more of something that is used in a certain place the cheaper that thing can become. A carbon tax in location A might make it economical to build a (or a larger) pipeline to move natural gas to location C, and then you get https://en.wikipedia.org/wiki/Jevons_paradox https://en.wikipedia.org/wiki/Jevons_paradox where carbon emissions increase much more in location C than they were reduced in location A.
