Tax vx. Cap-and Trade- Dion wins!

Tax vs. Cap-and-Trade
Note: The New York Times’ Nov. 2, 2007 on-line piece, The Real Climate Debate: To Cap or to Tax?, is a superb primer on the carbon-pricing debate. CTC’s Charles Komanoff is quoted for the carbon tax side. In addition, the Newshour with Jim Lehrer presented an excellent series of conversations about possible approaches to deal with global climate change. CTC’s Dan Rosenblum presented the carbon tax side in an April 11, 2007 interview.
CTC regards carbon taxes as superior to carbon cap-and-trade systems for six fundamental reasons:
1. Carbon taxes will lend predictability to energy prices, whereas cap-and-trade systems will aggravate the price volatility that historically has discouraged investments in less carbon-intensive electricity generation, carbon-reducing energy efficiency and carbon-replacing renewable energy.

2. Carbon taxes can be implemented much sooner than complex cap-and-trade systems. Because of the urgency of the climate crisis, we do not have the luxury of waiting while the myriad details of a cap-and-trade system are resolved through lengthy negotiations.

3. Carbon taxes are transparent and easily understandable, making them more likely to elicit the necessary public support than an opaque and difficult to understand cap-and-trade system.

4. Carbon taxes can be implemented with far less opportunity for manipulation by special interests, while a cap-and-trade system’s complexity opens it to exploitation by special interests and perverse incentives that can undermine public confidence and undercut its effectiveness.

5. Carbon taxes address emissions of carbon from every sector, whereas cap-and-trade systems discussed to date have only targeted the electricity industry, which accounts for less than 40% of emissions.

6. Carbon tax revenues can be returned to the public through dividends or progressive tax-shifting, while the costs of cap-and-trade systems are likely to become a hidden tax as dollars flow to market participants, lawyers and consultants.

Carbon Taxes Will Lend Predictability to Energy Prices. With carbon taxes ramped up through a multi-year phase-in, future energy and power prices can be predicted with a reasonable degree of confidence well ahead of time. This will make it possible for literally millions of energy-critical decisions — from the design of new electricity generating plants to the purchase of the family car to the materials used in commercial airframes — to be made with full cognizance of carbon-appropriate price signals. In contrast, a cap-and-trade program will exacerbate the volatility of energy prices since the price of carbon allowances will fluctuate as weather and economic factors affect the demand for energy. The vaunted advantage of cap-and-trade — that future levels of carbon emissions can be known ahead of time — is mostly notional, moreover, since most cap-and-trade systems under discussion include a "safety-valve" for auctioning off additional carbon allowances if the price of allowances exceeds a predetermined level. And even certainty in future emission levels is of questionable value, since there is no agreed-upon trajectory of emissions for achieving climate stability and preventing disaster. The real target for which the U.S. must aim is to reduce carbon emissions as much as possible, and then more.

Carbon Taxes Will Provide Quicker Results. The taxes themselves can be designed and adopted quickly and fairly. Cap-and-trade systems, by contrast, are devilishly complex and will take years to develop and implement. Thorny issues must be addressed intellectually and resolved politically; the proper level of the cap, timing, allowance allocations, certification procedures, standards for use of offsets, penalties, regional conflicts, the inevitable requests for exceptions by affected parties and a myriad of other complex issues must all be resolved before cap-and-trade systems can be implemented. During this time, polluters will continue to emit carbon with no cost consequences.

Carbon Taxes Are Transparent and Are Easier to Understand than Cap-and-Trade. A carbon tax is transparent and easy to understand; the government simply imposes a tax per ton of carbon emitted, which is easily translated into a tax per kWh of electricity, gallon of gasoline or therm of natural gas. By contrast, the prices for carbon set under a cap-and-trade system will vary with market fluctuations and be impossible even for big business (let alone small businesses or consumers) to predict. A cap-and-trade system will require a complex and difficult to understand market structure in order to balance the many competing interests and ensure that the trading system minimizes abuse and maximizes real carbon reductions.
A Carbon Tax’s Simplicity Inoculates it Against the Perverse Incentives and Potential for Profiteering that Will Accompany Cap-and-Trade. In contrast to the simple and straightforward process of implementing a carbon tax, the protracted negotiations necessary to implement a cap-and-trade system will provide constant opportunities for the fossil fuel industry and other invested parties to shape a system that maximizes their financial self-interests as opposed to an economically efficient system that maximizes societal well-being. If allowances are allocated based on some type of baseline reflecting past pollution (which has been the practice with NOx and SO2trading programs), rather than being auctioned, polluters will have perverse incentives to maximize emissions before the cap-and-trade system goes into effect in order to "earn" those pollution rights. (The voluntary carbon cap-and-trade system currently operating has already been criticized for questionable offsets that have produced huge profits but little environmental benefit. See Outsize Profits, and Questions, in Effort to Cut Warming Gases, New York Times, Dec. 21, 2006.)
Carbon Taxes Address All Sectors and Activities Producing Carbon Emissions. Carbon taxes target carbon emissions in all sectors — energy, industry and transportation — whereas at least some cap-and-trade proposals are limited to the electric industry. It would be unwise to ignore the non-electricity sectors that account for 60% of U.S. CO2 emissions.
Carbon Taxes Can Produce a Far More Equitable Result than Cap-and-Trade. As discussed in our Issue Paper, Managing the Impacts, carbon tax revenues can be returned through dividends or can be used to fund progressive tax-shifting to reduce regressive payroll or sales taxes. The costs of cap-and-trade systems, both implementation and the costs incurred as more expensive technologies replace older and less expensive coal-fired combustion, are far more likely to be imposed upon consumers with less possibility of rebating or tax-shifting. Moreover, because cap-and-trade relies on market participants to determine a fair price for carbon allowances on an ongoing basis, it could easily devolve into a self-perpetuating province of lawyers, economists, lobbyists and other market participants bent on maximizing their profits on each cap-and-trade transaction. As Holman W. Jenkins, Jr. stated in his Jan. 24, 2007 Wall Street Journal "Business World" column (subscription only):

General Electric, DuPont, Alcoa, Caterpillar and other industrial pigpens this week endorsed cap-and-trade limits on carbon dioxide, which would turn their established habit of using the atmosphere as a free waste disposal into a property right, worth billions. Talk about a low-hanging fruit. They are accustomed to treating carbon dumping as a gimme. Now they’d at least be in a position to get paid for dumping less.

The dollars that will be funneled into making the market work could be better spent reducing regressive taxes, protecting poorer households and/or helping consumers use less energy.

The "emissions certainty" touted by cap-and-trade supporters was recently put in perspective by the Financial Times: "[Carbon cap-and-trade systems] fix the amount of carbon abated, not its price. Getting the amount of emissions a little bit wrong in any year would hardly upset the global climate. But excessive volatility or unduly high prices of quotas on carbon emissions might disrupt the economy severely. [Carbon] taxes create needed certainty about prices, while markets in emission quotas [i.e., cap-and-trade systems] create unnecessary certainty about the short-term quantity of emissions." Financial Times, Carbon Markets Create a Muddle, April 26, 2007.

Note these two developments in the cap vs. tax debate last May:
First, CTC co-director Charles Komanoff examined the unsettling environmental politics behind cap-and-trade systems in a May 22, 2007 piece in Gristmill, while also debunking climate crisis denial from Nation columnist Alexander Cockburn. Environmental Defense posted a response, also in Gristmill. Our rejoinder to Environmental Defense can also be found in Gristmill. The full discussion is here on our blog. (In Feb. 2007, Gristmill also carried Environmental Defense’s argument against carbon taxing, and CTC’s rebuttal.)

Second, the Los Angeles Times ran a superb and comprehensive (1,600 words) editorial during the 2007 Memorial Day weekend, Time for a Carbon Tax. Under the banner, "A carbon tax is the best, cheapest and most efficient way to combat cataclysmic climate change," the editorial delivers a point-by-point refutation of arguments for settling for a carbon cap-and trade system. Here are key excerpts:

[F]or all its benefits, cap-and-trade still isn’t the most effective or efficient approach [for reducing carbon emissions]. That distinction goes to … 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.

The latter problem might be avoided in the U.S. by beefing up the Environmental Protection Agency. But there’s reason to suspect that many of the corporate interests pushing for a federal cap-and-trade program are hoping for a seat at the table when credits are passed out, and they will doubtless fudge numbers to maximize their credits; some companies stand to make a great deal of money under a trading system. Also hoping to profit, honestly or not, would be carbon traders. Large financial institutions would jump into the exchange to collect commissions on carbon trades, just as they do with crude oil and wheat. This presents opportunities for Enron-style market manipulation.

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.
