RE:Carbon tax ratesThe problem with carbon taxes is that several of the largest iron ore providing countries don't have one. Neither Brazil or Australia have a carbon tax. I know Vale has set an internal carbon price of 50 Dollars per ton for approval of a project and if they stick to it it should give a boost to the use of torches.Sweden has the largest carbon tax and why I think LKAB will be an aggressive adopter of GHG reduction technology.
