Architects of the Senate climate bill yesterday confirmed plans to limit state and federal climate change programs but signaled that a sweeping measure from Sen. George Voinovich goes further than they plan to. "The regulatory system set up in our bill would pre-empt the state governments and the federal government, including the power that EPA has certified by the court on greenhouse gases," said Sen. Joe Lieberman (I-Conn.), who will roll out draft climate legislation Monday with Sens. John Kerry (D-Mass.) and Lindsey Graham (R-S.C.).
