"A movement to divest from fossil fuel is gaining support among foundations as activists push for funding to be shifted away from coal, oil and natural gas. The call from activists to the charitable world is simple: Ditch fossil fuels and direct your investments into climate-friendly companies and funds. The worldwide divestment campaign has sought commitments from universities, corporations and other entities. Now, two of the biggest names in philanthropy — the Ford and MacArthur foundations — are reorienting their investments away from fossil fuels, a move that leaders of the divestment movement hope will prove to be a tipping point for the charitable world.... “We’re calling on governments and corporations to act on climate aggressively and commensurate with the science,” said Ellen Dorsey, executive director of the Wallace Global Fund and a leader in Divest-Invest Philanthropy, which is pushing the philanthropic community to dump its fossil fuel investments.... The MacArthur Foundation, an $8 billion organization known for its “genius grants,” pledged two years ago to halt new investments in oil and gas. It went further in September, saying it would switch to U.S. index funds that exclude fossil fuel companies. And it's aiming to change its global index funds to do the same within a year."
