Technical note: Carbon dioxide (CO_2) storage and sequestration Of land cover in the Leyte Geothermal Reservation

摘要

This study estimated the existing stored carbon (C) and rate of sequestration by vegetation that can potentially serve as a sink for the carbon dioxide emitted from eight geothermal plants in Leyte Geothermal Reservation, Philippines. For the 20,438 ha watershed in the vicinity of the power project, the total C storage is 3.84 Mt C(14.10 Mt CO_2) while C sequestration based on biomass change was 47.35 kt C (173.77 kt CO_2). Relative to power plant emission, the C stored in the reserve is equivalent to more than 22 years of CO_2 emission.
