Senators huddle over competing climate change plans

“They [Cantwell and Collins] have an approach. I respect it because it has the same goal that we have, which is to do something about global warming, and it does put a price on carbon,” Lieberman said before the meeting. “This is our attempt to reach out with them and see if we can find common ground.”

Graham and Kerry have recently said the structure of their plan remains under discussion, although Lieberman said Tuesday that “I think it will be cap-and-trade.” Discussions have included a cap-and-trade approach that covers fewer industry sectors than the “economy-wide” House cap-and-trade plan that passed in June.

Lieberman said the meeting was just one of many that he, Kerry and Graham are having with lawmakers and other groups. He noted talks last week with White House chief of staff Rahm Emanuel, and a separate session with officials from the U.S. Chamber of Commerce.

"We are really working hard to get something done this year and we are prepared to compromise,” he said.
