Forest aid pledges may reach €4.7bn
The money includes $3.5bn (€2.97bn) that was already promised at the United Nations climate summit in Copenhagen in December.
Those funds are due to be paid by the end of 2012. The countries, which include Japan, France, Australia and Germany, plan to boost funding to between $5bn and $6bn, Riese said in an interview. More countries may join, he added.
