Changing Climate for Carbon Taxes

Carbon taxes have recently become a major source of discussion in the Washington, DC policy community. Supporters contend that they offer an efficient way to simultaneously create incentives to emit less carbon dioxide and reduce the budget deficit. Should such a carbon tax be enacted, it will in all likelihood be accompanied by measures to ensure that the U.S. industries that would be most heavily affected by the tax are not placed at a competitive disadvantage with respect to competitor producers operating in countries that have not imposed any restrictions or taxes on carbon usage. Can such a carbon tax be applied in a way that does not violate U.S. obligations under the WTO Agreements?
