Senator Barbara Boxer (D-CA) said she is willing to wait on a federal climate change bill this year if weakening compromises become necessary to win passage. In a March 12 press conference, she noted that Senate majority leader Harry Reid (D-NV) promised to bring pending legislation, S. 2191, to the Senate floor after lawmakers return from their spring recess in May. The bill will continue to promote a cap-and-trade market for greenhouse gases and not a carbon tax, however. \u201cI can tell you [a carbon tax] is not going to happen here,\u201d said Boxer, chair of the Senate Environment and Public Works Committee. This is despite increasing skepticism in her home state among the media and environmental organizations about using emissions trading to reduce greenhouse gases when a carbon tax may be more efficient at cutting emissions. Boxer also said she would seek to change the bill to call for an 80 percent reduction in greenhouse gases by 2050 instead of the 63 percent cut it now seeks.
