Can a Dysfunctional Government Save the Planet? The most efficient way to begin attacking the global swelter is no mystery. It involves raising the price of carbon emissions, which are warming the planet, and then letting the private sector find innovative ways to use less dirty energy. Conservative economists, like Gregory Mankiw, support this approach. So do liberals, like Joseph Stiglitz.But taxing carbon has never had much of a political chance. It's too honest. It acknowledges that the best way to reduce the use of a product is to increase its price. We would all prefer a free lunch.So Congress has been laboring to disguise a price increase in a more palatable package. [NYT]
