Martin Feldstein on the proposed cap and trade bill:

The Congressional Budget Office recently estimated that the resulting increases in consumer prices needed to achieve a 15 percent CO2 reduction — slightly less than the Waxman-Markey target — would raise the cost of living of a typical household by $1,600 a year. Some expert studies estimate that the cost to households could be substantially higher. The future cost to the typical household would rise significantly as the government reduces the total allowable amount of CO2.

Americans should ask themselves whether this annual tax of $1,600-plus per family is justified by the very small resulting decline in global CO2. Since the U.S. share of global CO2 production is now less than 25 percent (and is projected to decline as China and other developing nations grow), a 15 percent fall in U.S. CO2 output would lower global CO2 output by less than 4 percent. Its impact on global warming would be virtually unnoticeable. The U.S. should wait until there is a global agreement on CO2 that includes China and India before committing to costly reductions in the United States.

The CBO estimates that the sale of the permits for a 15 percent CO2 reduction would raise revenue of about $80 billion a year over the next decade. It is remarkable, then, that the Waxman-Markey bill would give away some 85 percent of the permits over the next 20 years to various businesses instead of selling them at auction. The price of the permits and the burden to households would be the same whether the permits are sold or given away. But by giving them away the government would not collect the revenue that could, at least in principle, be used to offset some of the higher cost to households.

The Waxman-Markey bill would give away 30 percent of the permits to local electricity distribution companies with the expectation that their regulators would require those firms to pass the benefit on to their customers. If they do this by not raising prices, there would be less CO2 reduction through lower electricity consumption. The permit price would then have to be higher to achieve more CO2 reduction on all other products. Some electricity consumers would benefit, but the cost to all other American families would be higher.

In my judgment, the proposed cap-and-trade system would be a costly policy that would penalize Americans with little effect on global warming. The proposal to give away most of the permits only makes a bad idea worse. Taxpayers and legislators should keep these things in mind before enacting any cap-and-trade system.

If we are intent on reducing carbon emissions, I much prefer a carbon tax that is transparent. Cap and trade is not as effective and has the added benefit of political corruption.

I support a carbon tax as long as it is offset by reductions in other taxes. My support has nothing to do with carbon emissions, but is rooted in foreign policy. If we can reduce the amount of dollars flowing to the Middle East, Russia and Venezuela, I am all for it. Cap and trade will not accomplish the task.
