The contributors to the haze appear not primarily to be the larger oil palm plantation operators but relatively small estates, owning perhaps only one or two mills, or independent mills depending largely, if not exclusively, on fruit submitted from smallholders.
Many such operators and smallholders have no wish to comply with sustainability principles.
Could the Monetary Authority of Singapore instruct banks operating in Singapore not to extend financing and trading facilities to companies linked to mill owners who are not in compliance with agreed sustainability principles as required by the Indonesian Sustainable Palm Oil (ISPO) or Roundtable on Sustainable Palm Oil (RSPO) standards?
These companies should also be required to provide independently certified reports that they have assisted all mill owners and smallholders submitting fruit to their mills in complying with the sustainability principles of ISPO or RSPO.
Other central banks in the region could also adopt similar measures.
