20 Aug 2015 --- Norway's gigantic sovereign wealth fund has announced it is divesting from four large Asian companies over the environmental damage their palm oil activities have on tropical forests. The world's largest public investment fund, managing 7.15 trillion kroner (785 billion euros, $872 billion), said its decision to exclude four groups -- including South Korean group Daewoo International -- from its portfolio was based on "an assessment of the risk of severe environmental damage" from their conversion of tropical forests to cultivate palm oil.
