The Obama administration has privately concluded that a cap and trade law would cost American taxpayers up to $200 billion a year, the equivalent of hiking personal income taxes by about 15 percent.
A previously unreleased analysis prepared by the U.S. Department of Treasury says the total in new taxes would be between $100 billion to $200 billion a year. At the upper end of the administration's estimate, the cost per American household would be an extra $1,761 a year.
A second memorandum, which was prepared for Obama's transition team after the November election, says this about climate change policies: "Economic costs will likely be on the order of 1 percent of GDP, making them equal in scale to all existing environmental regulation."
The documents (PDF) were obtained under the Freedom of Information Act by the free-market Competitive Enterprise Institute and released on Tuesday.
