“I think we need a ‘carbon freeze,'” the former vice president told a two-day closed meeting in Berkeley organized by the Greentech Innovation Network, a group led by Silicon Valley firm Kleiner Perkins Caufield and Byers.

John Denniston, a Kleiner Perkins partner, told reporters that his firm, which has pledged to invest $200 million to fund green technology start-ups, is prepared to help finance Gore’s political efforts — at least, that’s what Reuters reports. Hmm, that sounds odd. Wonder what Kleiner’s own investors — many of them conservative — would say about this? We’re checking with Kleiner whether this is accurate.

(Update: Denniston clarifies for VentureBeat: “I did not tell Reuters KP is providing funding. What I said was I believe KP will collaborate with Al Gore’s efforts.”)

Gore said he’ll enlist groups ranging from entrepreneurs and activists to political leaders to push for stronger policies to limit the growth of greenhouse gases.
