The technology for carbon dioxide sequestration has gained wider interest in recent years. This study estimates the carbon dioxide sequestered and stored in the forest trees of Jose Rizal Memorial State University – Tampilisan Campus reservation. The study site contained the trees species Mohagany (Swietenia macrophylla), Gmelina (Gmelina arborea), Mangium (acacia magium) Rubber (Hevea brasilliensis) and natural forest trees (e.g. Dipterocarp species, etc). Results revealed that standard – sized trees have better CO2 sequestration potential than the sapling and pole – sized. These trees have the biggest merchantable height, trunk diameter and wood density. Among the species considered, Gmelina had the highest amount of CO2 sequestered and stored in stem followed by Mangium, Rubber and Mahogany at standard size. In addition, regression analysis indicated that the rate of CO2 sequestered and stored on trees are related to the growth characteristics as trunk diameter (DBH) and total height, but not with wood density. Moreover, the forest stand of JRMSU – Tampilisan Campus reservation has a total sequestration capacity of 88.17 kT CO2.
