Harvested wood product is one of the carbon pools that need to be considered in calculating carbon emission related to forestry sector. There are several models of wood product retirement based on scientific based experiment: linear, logistic, and exponential. The application of these models in wood product pool calculation may result in different amount of carbon stored in wood product, and hence may result in different management regime of a plantation forest. This paper aims to analyze how different models of wood product oxidation result in different amount of carbon stored in sengon wood product and may cause different optimal management of sengon plantation. The models used in this paper include linear (VCS model), exponential (Winjum), and logistic (Miner et al model.). The focus of the paper is only for long term wood product that is oxidized until 100 years. The results of the study show that the lowest greenhouse gases (GHG) emissions from end use wood product of sengon are those estimated by linear, logistic, and exponential respectively.
