White House memo challenges EPA finding on warming

"An Environmental Protection Agency proposal that could lead to regulating the gases blamed for global warming will prove costly for factories, small businesses and other institutions, according to a White House document."

"The nine-page memo is a compilation of opinions made by a dozen federal agencies and departments during an internal review before the EPA issued a finding in April that greenhouse gases pose dangers to public health and welfare."

"That finding could set in motion for the first time the regulation of six heat-trapping gases from cars and trucks, factories and other sources under the Clean Air Act."

"The document, labeled "Deliberative-Attorney Client Privilege," says that if the EPA proceeds with the regulation of heat-trapping gases, including carbon dioxide, factories, small businesses and institutions would be subject to costly regulation."

"Making the decision to regulate carbon dioxide ... is likely to have serious economic consequences for regulated entities throughout the U.S. economy, including small businesses and small communities," the document says."
