Listen to Mark Lieberman’s interview with Dan Becker, the Director of the Center for Biological Diversity’s Safe Climate Transport Campaign. Dan fought in Congress for the Clean Air Act, CAFE standards, Superfund and other responsible energy policies. He led the clean-car fight beginning in 1989 as director of Sierra Club’s Global Warming and Energy Program. His rock-star status was further burnished when he was named one of the world’s 28 “Climate Heroes” by Rolling Stone magazine and Salon.com.
