Update: BP explains decision to leave USCAP

BP spokesman Ronnie Chappell describes the company's decision to leave the U.S. Climate Action Partnership this way:

"We think that USCAP has accomplished the work that we thought important when we joined, which was the establishment of a principles-based framework for shaping climate change legislation,” he told The Hill. "We think that the [USCAP] blueprint for legislative action is a great piece of work, and we continue to support climate change legislation that conforms to the blueprint.”

“We don’t believe that legislation pending in the Congress meets that standard yet, and we have concluded that as the climate change discussion goes forward and as the proposals become more specific, we can become more effective if we show up at that discussion as BP,” he added.
