Citizens’ Climate Lobby (CCL) is an international grassroots environmental group that trains and supports volunteers to build relationships with their elected representatives in order to influence climate policy. Operating since 2007, the goal of CCL is to build political support across party lines to put a price on carbon, specifically a revenue neutral carbon fee and dividend (CF&D) at the national level. CCL is supported by notable climate scientists James Hansen, Katharine Hayhoe, and Daniel Kammen. CCL's advisory board also includes former Secretary of State George Shultz, former US Representative Bob Inglis, actor Don Cheadle, and RESULTS founder Sam Daley-Harris.
