Markup of Clean Energy Bill Begins in Senate Republicans boycott markup session. Published on: Nov 4, 2009 Tweet Post to Your Wall. Email Story RSS Permalink Print Despite a significant number of empty chairs, the Senate Environment and Public Works committee took about two hours of opening statements Tuesday, as the panel began markup of the Clean Energy Jobs and American Power Act. Chairman Barbara Boxer, D-Calif., termed the session a business meeting, a term that permits markup despite the absence of at least two Republicans at the table. Committee Republicans followed through on a threat to boycott the session, saying they won't begin to work on the bill until they see a full cost analysis of the measure, which would cap greenhouse gas emissions and establish a market for trading government-issued pollution allowances. One Republican, George Voinovich of Ohio, did appear at the committee meeting, offering a lengthy plea to Boxer to delay the markup until the EPA completes a cost analysis that it says would take about five weeks. Voinovich said this is not a stalling tactic, nor a ruse to delay marking up a climate bill. This is an attempt to get the best information about a bill that will affect the entire country.
