Forest owners want full access to credits. But insurers suggest half should be retained in buffer funds in case forests vanish in a few decades. If a forest disappeared, credits in the funds would go to the insurers.”How much land managers will see of the price is what the excitement is about,” said Frances Seymour, the head of the Centre for International Forestry Research in Indonesia. Placing a value on forests could give developing nations in Africa, Latin America and Asia a big incentive to do more to slow rising greenhouse gas emissions. But the economic slowdown may make rich nations reluctant to take part.
