Holman Jenkins, Jr. makes a good case for a carbon tax because of its economic efficiency (“Is a Carbon Tax the Only Way to Stop the Greens?” Business World, July 9). He suggests a compromise deal “that’s been on the table for decades”—a trade for pro-growth tax cuts “would be a tonic for the economy.”

Such a bargain could be an elixir, but environmentalists want a carbon tax not as a substitute but as an addition to command-and-control regulations. If a Pareto-optimal carbon tax could be determined, then vehicle fuel-economy standards should be scrapped along with whatever residual carbon-regulating authorities remain with the EPA after the recent Supreme Court decision filters through. Unfortunately, the inertia of government won’t let that happen.

Mr. Jenkins is not correct that a carbon tax would “bring us all the energy we want . . . without running a gantlet of environmentalists trying to shut [fossil energy] down.” The opposition to oil and gas is fundamentally ideological, derived from opposition to modern industrial society, which would be impossible without fossil fuels. The left opposes a carbon tax because the revenues will expand the political coalition favoring robust fossil-fuel production and carbon-tax revenues over the long run.

Besides, a reduction in capital taxation financed with an increase in energy costs is not viable politically. Even a carbon tax adopted on an international basis would have an impact on climate phenomena close to zero. Efforts to minimize the adverse competitive effects of a carbon tax in the context of international trade would be hugely complex, and would engender a massive shift toward resource allocation driven by government.
