Chairman’s Mark of Lieberman-Warner Climate Bill Released

Washington, DC (November 28, 2007)- The House Climate Change Caucus held a Congressional briefing on America’s Climate Security Act (S. 2191) and discussed changes that have been made to the bill under the Chair’s markup of the bill. The Chair’s mark was released by Sen. Barbara Boxer (D-CA), chairwoman of the Environment and Public Works Committee. Senators on the Environment Committee will likely vote on the bill when it is marked up in committee on December 5-6.


One of the biggest changes involves an “upstream” cap placed on the heat-trapping greenhouse gas emissions that come from natural gas processors. With the new bill’s natural gas section, more than 80 percent of the greenhouse gas emissions that come from the US economy will be covered under the legislation. Another change in the legislation speeds up by five years the end date for the free emission credits given out to power plants, manufacturers and other industrial sources. Free credits will now be phased out at the start of 2031, rather than the start of 2036. The legislation also creates a separate cap for one of the most potent types of greenhouse gases: hydrofluorocarbons, or HFCs. Other changes are included in the mark as well.
