"Earlier this year our organization, the Rockefeller Family Fund (RFF), announced that it would divest its holdings in fossil fuel companies. We mean to do this gradually, but in a public statement we singled out ExxonMobil for immediate divestment because of its “morally reprehensible conduct.” For over a quarter-century the company tried to deceive policymakers and the public about the realities of climate change, protecting its profits at the cost of immense damage to life on this planet. ...Exxon, in particular, has been a leader of the movement to deny the facts of climate change. Often working indirectly through front groups, it sponsored many of the scientists and think tanks that have sought to obfuscate the scientific consensus about the changing climate, and it participated in those efforts through its paid advertisements and the statements of its executives. It seemed to us, however, that for business reasons, a company as sophisticated and successful as Exxon would have needed to know the difference between its own propaganda and scientific reality. If it turned out that Exxon and other oil companies had recognized the validity of climate science even while they were funding the climate denial movement, that would, we thought, help the public understand how artificially manufactured and disingenuous the “debate” over climate change has always been. In turn, we hoped this understanding would build support for strong policies addressing the crisis of global warming."
