A carbon tax will also enable the United States and Europe to press China and India to reduce their carbon emissions. A properly designed tax would apply not only to domestic goods and services, but to imports as well.
China and India would discover that their products no longer seem so cheap when a carbon tax at the border adds back the environmental costs of dirty manufacturing. To export to the world's richest consumers, China and India will have to clean up their act -- an incentive more persuasive than a hundred Doha conferences.
More jobs and growth; reduced deficits without raising income taxes; lower taxes for middle-class families; a kick in the pants to Chinese polluters; and more happiness for American commuters -- one policy instrument can do it all. What's not to love about a carbon tax?
