Why Progressives Should Love a Carbon Tax—Although Not All of Them Do

Progressives should love a carbon tax. Most progressives love the environment and believe that carbon emissions cause environmental harm. Unlike conservatives, whose attitudes toward carbon taxes were the subject of my last post, progressives have no generalized aversion to taxes. Carbon taxes should be a natural for progressives, then, if they can accept the power of economic incentives to slow the destruction of the planet.

To be sure, many progressives do express strong support for carbon taxes. Here are just three of many examples:

• The Center for American Progress has put out a position paper titled “A Progressive Carbon Tax Will Fight Climate Change and Stimulate the Economy.” It argues that climate change, economic growth, and fiscal responsibility are intimately linked, and that a price on carbon should be part of a policy to deal with each of these issues.
• Gernot Wagner, an economist at the Environmental Defense Fund, argues that it makes eminent sense to tax what you want less of in his excellent book, But Will the Planet Notice: How Smart Economics Can Save the World.
• In Green Illusions: The Limits of Alternative Energy Ozzie Zehner argues against the wishful thinking that solar, wind, or other technological fixes will bring a future of cheap, clean, and abundant energy. Insisting that a strong push for energy conservation has to be part of the mix, he advocates carbon taxes to counteract what he calls “the boomerang effect”—the tendency for subsidies for clean energy to make energy in general cheaper, therefore discouraging conservation.

Yet, not all progressives are convinced. Many are skeptical on principle of our capitalist economic system and instinctively distrust market-based environmental policy. Others fear that a carbon tax would disproportionately harm the poor. Still others have ethical objections to the whole idea of bribing people to do things they ought to choose voluntarily, out of love and respect for the planet. Let’s look at each of these objections in turn. >>>Read more
