Description:
For the focus areas Batang Toru and Tripa in the two main orangutan habitats (forest on non-peatlands and peat) it was calculated what the values (USD/ha) would be of the avoided CO2 emissions over a period of 25 years. For Batang Toru these ranged from 3,711-11,185 USD/ha and for Tripa from 7,420-22,094 USD/ha. Net present values (NPV) per hectare were calculated using the model in Butler et al. (2009) with the following prices (range per tCO2 is USD 9.43-17, Hamilton et al. 2009). Calculations were made under a scenario where carbon prices remained constant during 25 years or appreciated 5% annually during that period). Carbon values were calculated with an equal allocation model for 25 years (Butler et al. 2009) at a 6.5% discount rate. Carbon stock in agricultural land uses was not included. Above-ground carbon assessment came from the ICRAF rapid assessment report (Tata and van Noordwijk 2010) for Tripa (forest on peat) and Batang Toru (forest on non-peat). Values for the los ...
