Exxon to Congress: Give Us A Carbon Tax, Please!

"The chief executive of Exxon Mobil Corp. for the first time called on Congress to enact a tax on greenhouse-gas emissions in order to fight global warming.

Rex Tillerson said that a tax was a "more direct, a more transparent and a more effective approach" to curtailing greenhouse gases than other plans popular in Congress and with the incoming Obama administration.

The policy he is advocating is often called a carbon tax because it would be imposed on emissions of carbon dioxide, the most common man-made greenhouse gas.

Carbon taxes have been politically unpopular. "Calling for a carbon tax could be a ploy because few observers believe such a tax is politically feasible in our Congress," says Daniel J. Weiss, a fellow at the Center for American Progress, a left-of-center think tank in Washington.

ConocoPhillips and the U.S. divisions of BP PLC and Royal Dutch Shell PLC have all supported a cap-and-trade solution."
