With the Senate already having voted on an energy bill and the House expected to take up energy legislation this month, the next course of action expected after the August recess will be a debate on emissions reduction legislation. Will Congress favor a cap-and-trade approach or a carbon tax? Are there enough votes in the House and Senate to pass a climate bill? During today's OnPoint, Eileen Claussen, president of the Pew Center on Global Climate Change, discusses Sens. Jeff Bingaman (D-N.M.) and Arlen Specter's (R-Pa.) recently introduced climate bill. She explains why she believes the safety valve option is not the best approach and compares cap-and-trade to a carbon tax.
