An aerial view shows a palm oil plantation in Indonesia’s Jambi province August 5, 2010. Indonesia may propose palm oil plantations be eligible to earn carbon credit under a U.N.-backed scheme aimed at preserving forests, a forestry ministry official said on Monday. Environmentalists have for years expressed concerns over Indonesia’s palm oil producers and whether they have cleared forests to expand their plantations. Picture taken on August 5, 2010.
