Last week, the House Energy and Commerce Committee passed historic legislation that would control U.S. greenhouse gas emissions, attempt to put the brakes on global warming and promote green energy technologies. But the committee vote is just the first step in getting climate change legislation to the president's desk. The measure is expected to get close scrutiny in the House Agriculture Committee, where Chairman Collin Peterson, D-Minn., has been critical of the legislation. It also awaits review by Ways and Means Committee members, some of whom would prefer a carbon tax instead of a cap-and-trade program.
What are the most daunting hurdles standing between the legislation and House approval? How likely is the bill to clear them?
