The &quot;regressive&quot; part of the tax can be mitigated just by rebating some (most?) of the money back to the people who would be most impacted. The rest can be used for R&amp;D into clean energy, power grid improvements, etc.<p>The bigger issue is making sure the tax is applied consistently everywhere, otherwise we just move polluting industries to countries with lax enforcement and put countries that <i>are</i> enforcing the tax at a disadvantage.
