According to White House briefing http://www.whitehouse.gov/news/releases/2007/12/20071218-2.html "Tomorrow we look forward to, hopefully, passing -- the President signing the Energy Independence and Security Act of 2007. That bill will be voted on for final passage in the House later today. In January, the President announced his 20-in-10 initiative, a comprehensive plan for a more secure, cleaner energy future, which would reduce our consumption of gasoline by 20 percent over 10 years. He has pushed Congress to pass this legislation all year. And the bill would increase fuel economy and expand the use of renewable fuels; it will save billions of gallons of fuel, expand our energy security and reduce greenhouse gas emissions. While the President's alternative fuel standard and CAFE proposal would have gone farther and faster, we are pleased that Congress has worked together on a bipartisan way that provides the chance for the President to sign a bill that does not include tax increases."
