For example, Indonesia is seeking to establish a Green Corridor in Kalimantan (the Indonesian portion of the island of Borneo), where deforestation is not only fueling greenhouse-gas emissions, but also diminishing river flows, making it difficult in some months to transport goods by barge. Given that transportation by barge costs about $10 a ton, compared to close to $60 a ton by road, REDD+ offers a chance to hold down greenhouse-gas emissions while preserving an economically important sector.
