GREEN RANKING FOR 2009

Green investment: Sustainable agriculture

The grandson of John D Rockefeller, founder of Standard Oil, the giant that fuelled the American industrial revolution, David Rockefeller has become one of the great philanthropists in America. He gave away some $770m between 2004 and 2008. He pledged $25m to the Stone Barns Center for Food & Agriculture, devoted to sustainable agriculture and food education, that sits on farmland his family has owned for close to a century in New York. At a recent Exxon Mobil annual meeting, Rockefeller family members demanded the company adopt greener measures. In October last year Forbes ranked Rockefeller’s fortune at about £2 billion. With falling asset prices, we cut him back to £1.7 billion.
