If carbon taxes go up, miners will be incentivized to pursue low/no-carbon alternative energy sources, thereby accelerating the shift to cleaner energy. Mining can either be viewed as creating a profit incentive where none existed before, or at least enhancing the profit incentive even further. Clean energy needs more profit incentives to really scale adoption.

I am all for carbon taxes, to shape the market towards cleaner energy. And I do think it will successfully push miners even faster towards adoption of other energy sources.
