Abstract: Global climate change recently caused by disturbance of energy balance between earth and atmosphere. The disturbance is the result of some factors, particularly, the increase of carbon dioxide (CO2), methane (CH4), and Nitrous Dioxide (N2O), which are known as green house gasses. Landuse change from forestry to agricultural land and estate crop leads to species change and its composition. One of alternatives to increase the carbon stock, especially on degaraded lands, is industral forest plantation which aimed to retain natural carbon stock. Sequestration of CO2 from the atmosphere by vegetation is mainly estimated using carbon stock estimation in plant biomass, necromass, and soil organic matter. This study was conducted in A. mangium wild and E. pellita industrial forest plantation in Jorong Sub-district, Tanah Laut District. The purpose of this study is to gain information about the quantity of carbon stock on industrial forest plantation which consists of A. mangium wild and E. pellita Plants, based on their stucture and species composition. The objectives of the research were to analyze the amount of (1) To estimate the carbon stock of A. mangium wild-based industry forest plantation; (2) To estimate the carbon stock of E. pellita in industry forest plantation. The result shows that biomass of A. mangium figures on 95.167 ton/ha which is more than E. pellita on 51.32 ton/ha. The same result is shown on the understory’s biomass of A. mangium on 0.89 ton/ha which is more than 0.50 ton/ha on Eucalyptus pellita. Biomass of necromass of A. mangium records on 39.68 ton/ha which is more than the E. pellita on 13.18 ton/ha. In summary, carbon stock on organic matter in industrial forest plantation of A. mangium figures on 20.23 ton/ha which is more than E. pellita on 12.1 ton/ha. REDD project payments are made with a full payment mechanism at the start of the project (full ex-ante credit). The carbon price uses a hypothetical price folks $ 6, US $ 9, and US $ 12 per ton of CO2 (ha-1). The quantity of CO2 absorbed by A. mangium and E. pellita converted to US $ per hectare. A. mangium obtained the highest economic value as carbon price per ton CO2 increase (from US$1,871.604, and 1,403.703 to US$9,35.805). The E. pellita Plants (from US$ 925.20, and 693.90 to US$1462.60) and results indicate that with an increase in carbon price, there is a corresponding increase in economic value Industry forest plantation.
