The forest sector in the Philippines has the potential to be amajor sink for carbon (C). The present study was conducted to evaluatepotential forestry mitigation options in the Philippines using the Comprehensive Mitigation Assessment Process (COMAP)model. The baseline scenario (BAU) assumes that current trends continue upto the year 2030 (`business-as-usual'). Two mitigation scenarios wereevaluated: high scenario (HS) and low scenario (LS). The former ispatterned largely from the government's forest master plan while thelatter assumes a 50% lower success rate of the master plan.The results of the analyses show that by 2030, the total C stock of thePhilippine forest sector in the baseline scenario decreases to 814× 106 Mg C,down by 37% compared to the 1990 level. The C stocks of the HS andLS mitigation scenarios were 22% and 18% higher than the BAU,respectively. Of the mitigation options assessed, long rotation plantationsand forest protection activities produce the greatest C gain (199 and 104× 106 Mg, respectively under HS). The not present value (NPV)of benefits is highest in the bioenergyoption with $24.48 per Mg C (excluding opportunity costs) at a realdiscount rate of 12%. However, the investment and life cycle costs arealso highest using bioenergy.The study also estimated potential investments needed under the mitigationscenarios. The investment requirement for the LS amounts to $263× 106 while for the HS it is $748 × 106. Finally, policy issues anddecisions that may be useful for the Philippines to evaluate LULUCFmitigation options under the UNFCCC Kyoto Protocol, are identified anddiscussed.
