Any honest economist will tell you that a carbon cap and trade scheme, if it works perfectly, functions the same as an energy tax. The Waxman-Markey cap and trade bill currently under consideration in Congress is no different. In 2007, MIT did a study on the costs of cap and trade and found that cap and trade proposals that would reduce carbon emission by 50% to 80% below 1990 levels by 2050 would cost the American household $800 a year in economic losses and $3,100 a year in taxes collected by the federal government. That’s a total $3,900 cost for the average American household! How does this cost compare to other household expenses?
