A carbon tax is the best, cheapest and most efficient way to combat cataclysmic climate change.
In 1995, the federal government launched a cap-and-trade program for sulfur dioxide, the main ingredient in acid rain. The goal was to reduce emissions to half their 1980 levels by 2010, and the program is expected to reach it or fall just short. It has become a model worldwide, leading signatories to the Kyoto Protocol to pursue an international cap-and-trade system for greenhouse gases.
And yet for all its benefits, cap-and-trade still isn't the most effective or efficient approach. That distinction goes to Method No. 3: a carbon tax. While cap-and-trade creates opportunities for cheating, leads to unpredictable fluctuations in energy prices and does nothing to offset high power costs for consumers, carbon taxes can be structured to sidestep all those problems while providing a more reliable market incentive to produce clean-energy technology.
To understand the drawbacks of cap-and-trade, one has to look not only at the successful U.S. acid rain program but the failed European Emissions Trading Scheme, the first phase of which started in January 2005. European Union members each developed emissions goals, then passed out credits to polluters. Yet for a variety of reasons, the initial cap was set so high that the polluters fell under it without making any reductions at all. The Europeans are working to improve the scheme in the next phase, but their chances of success aren't good.
One reason is the power of lobbyists. In Europe, as in the U.S., special interests have a way of warping the political process so that, for example, a corporation generous with its campaign contributions might win an excessive number of credits. It's also very easy in many European countries to cheat; because there aren't strong agencies to monitor and verify emissions, companies or utilities can pretend they're cleaner than they are.
Cap-and-trade would also have a nasty effect on consumers' power bills. Say there's a very hot summer week in California. Utilities would have to shovel more coal to produce more juice, causing their emissions to rise sharply. To offset the carbon, they would have to buy more credits, and the heavy demand would cause credit prices to skyrocket. The utilities would then pass those costs on to their customers, meaning that power bills might vary sharply from one month to the next.
That kind of price volatility, which has been endemic to both the American and European cap-and-trade systems, doesn't just hurt consumers. It actually discourages innovation, because in times when power demand is low, power costs are low, and there is little incentive to come up with cleaner technologies. Entrepreneurs and venture capitalists prefer stable prices so they can calculate whether they can make enough money by building a solar-powered mousetrap to make up for the cost of producing it.
Carbon taxes avoid all that. A carbon tax simply imposes a tax for polluting based on the amount emitted, thus encouraging polluters to clean up and entrepreneurs to come up with alternatives. The tax is constant and predictable. It doesn't require the creation of a new energy trading market, and it can be collected by existing state and federal agencies. It's straightforward and much harder to manipulate by special interests than the politicized process of allocating carbon credits.
And it could be structured to be far less harmful to power consumers. While all the added costs under cap-and-trade go to companies, utilities and traders, the added costs under a carbon tax would go to the government — which could use the revenues to offset other taxes. So while consumers would pay more for energy, they might pay less income tax, or some other tax. That could greatly cushion the overall economic effect.
There is a growing consensus among economists around the world that a carbon tax is the best way to combat global warming, and there are prominent backers across the political spectrum, from N. Gregory Mankiw, former chairman of the Bush administration's Council on Economic Advisors, and former Federal Reserve Chairman Alan Greenspan to former Vice President Al Gore and Sierra Club head Carl Pope. Yet the political consensus is going in a very different direction. European leaders are pushing hard for the United States and other countries to join their failed carbon-trading scheme, and there are no fewer than five bills before Congress that would impose a federal cap-and-trade system. On the other side, there is just one lonely bill in the House, from Rep. Pete Stark (D-Fremont), to impose a carbon tax, and it's not expected to go far.
The obvious reason is that, for voters, taxes are radioactive, while carbon trading sounds like something that just affects utilities and big corporations. The many green politicians stumping for cap-and-trade seldom point out that such a system would result in higher and less predictable power bills. Ironically, even though a carbon tax could cost voters less, cap-and-trade is being sold as the more consumer-friendly approach.
