A policy advocacy organization dedicated to free enterprise and limited government, CEI generally espouses a market-oriented, anti-regulatory agenda and opposes the mandatory emission controls of the Kyoto Protocol. Myron Ebell,  CEI's director of energy and global warming policy, rivals Michaels and Singer for highest-profile skeptic, and judging from his CEI online bio  seems to relish the criticism lobbed his way by environmental activists. CEI's 20th annual program online (2004) does not identify individual donors, but says 52 percent of its revenues came from foundations, 31 percent from corporations and 16 percent from individuals. ExxonMobil, alleged by environmental activists to be a longtime underwriter, recently announced it no longer funds CEI. SourceWatch . Wikipedia .
