14 Aug 2018 --- More than 90 institutional investors representing more than US$6.7 trillion in assets have called on the Roundtable on Sustainable Palm Oil (RSPO) to strengthen its standards for certifying the sustainable production of palm oil. In a letter sent earlier this month to the RSPO, investors voiced their concerns over the group’s relevance and effectiveness and the current disconnect between corporate policy commitments and the RSPO’s Principles and Criteria Guidance. The investors outline specific recommendations to help bridge the gap.
