I like
Ed Begly Jr, but he really doesnt appeal to the younger crowd. I think
Matthew McConaughey or
Natalie Portman get followed closely, and they seem to be conscious of their public image along with current issues pertaining to environmantal concerns.
Regardless of anyones personal feelings towards the movie "An Inconvenient Truth", it would not be hard to find the celebrities that were the most vocal about that. I seem to remember that
Leonardo DeCaprio was a big supporter. "...DiCaprio has made several films to educate the public about environmental issues, including "11th Hour". He also serves as the Honorary Chairman of the Board of Directors of the Pacific Palisades-based Reef Check Foundation..."
edit: just played with my Google, "the Alliance for Climate Protection" lists
Michael Mckean,
Rob Reiner (producer, director, actor),

Aston Kutcher was recently caught by the paparazzi driving a 7-MPG mega-truck (much to his embarrassment), so he might be interested in trying to re-gain some green-cred, couldn't hurt to ask?
