llm'trtl Status 5mm WASHINGTON, DC 205l0 October 29, 2015 Mr. Rex ilierson Chairman ofthe Board and Chief Executive Of?cer l-"ixxon Mobil 5959 Las (?olinas Boulevard Irving, 'l'cxas 75039-2298 Dear Mr. l'illerson. We?ve been lbllowing lixxonMobil?s response to the recent investigations into your company by the Los Angefes Times, InsideCHmme News, and others. You and other Exxon spokespeople acknowledge that Exxon has been conducting climate change research since the 1970s. A post on iixxonMobil?s website on October 21, 2015 quotes Ken Cohen, ExxonMobil?s vice president ol?pubiie and government affairs, as saying ExxonMobil has worked to develop ?climate science in partnership with governments and academic institutions, and did and continue[s] to do that work in an open and transparent way.? Over the years, we have seen Exxon support climate denial and anti-climate policy advocacy through a variety of foundations and advocacy groups, such as the Heartland Institute, the American Legislative Exchange Council, and the Competitive Enterprise Institute. In the mid- 2000s, ExxonMobil pulled its funding from some ofthose organizations. Soon thereafter, Donors Trust and Donors Capital Fund began to increasingly support climate denial groups. According to research by Dr. Robert Brulle oI?Drexel University. the Donors Capital Fund operation does double duty: it is the "central component" and "predominant Yonder? ol? the denier apparatus. and at the same time it is the "black box that conceals the identity ol? contributors." 'I?hc correiation between ExxonMobil?s decision not to fund some groups openly associated with climate change denial, and the increase in anonymous funding from a group that does is "suggestive of an effort" to simply reroute its support'. That would not be consistent with Mr. Cohen?s claim that ExxonMobil continues to work in an ?open and transparent way.? To assess the accuracy of Mr. Cohen?s statement, please detail whether ExxonMobil, the Exxon Foundation. or any ol? your company?s affiliates has contributed or matched employee donations to Donors 'i?rust and Donors (?apital since 2000. and if so, how much each has contributed.
