Convenient Truth

Jonathan Rausch makes the obvious point that a carbon tax is the best way to deal with global warming and has good side effects:

Just as conveniently, the most efficient way to get started is also the simplest, albeit not the easiest politically: tax carbon emissions. "At around $30 per ton of CO2 over a 25-year horizon, experts seem to think this is the kind of price that will encourage the kind of technologies that are necessary," says Billy Pizer, an environmental economist at Resources for the Future, a Washington think tank. That would translate into an additional 27 cents or so on a gallon of gasoline and about a 20 percent increase in residential electricity bills (more like 34 percent for industrial users). Unpleasant, but hardly radical. Perfectly do-able, in fact.

Fortuitously, a carbon tax could also reduce the U.S. budget deficit and the geopolitical leverage of sinister "petrocracies" such as Iran, Russia, and Venezuela. Policy prescriptions don't come any more convenient than that.
