Indonesia, the world’s biggest palm oil producer, is offering incentives to developers of a new 100 percent palm oil-based “green diesel”, which the net oil importer hopes can replace costly fuel imports within three years, Reuters reports. Palm oil producers are rethinking their trade strategy amid rising challenges. Facing a backlash in Europe over palm oil’s environmental toll, the world’s top producers are scrambling to find new markets and even striking unusual barter deals, such as exchanging Sukhoi jets for the edible oil. Palm oil sourced from illegally cleared rainforest areas in Indonesia has flowed through traders to major consumer goods brands despite widespread commitments to cease purchases of non-sustainable oil, according to a report by Eyes on the Forest (EoF), a coalition of environmental NGOs including WWF-Indonesia.
