Mitigating the impacts of climate change has been a global effort of the century. Studies show the potential of bamboo as carbon sink which helps lowering the risks of climate change. This paper conducted a research study on carbon stock assessment of the three bamboo plantations located at Claveria, Misamis Oriental, Malaybalay City and Maramag Bukidnon with the following species Dendrocalamus asper, Bambusa philippinensis and Schizostachyum lumampao, respectively. Destructive method was conducted for the estimation of aboveground biomass (culms, twigs and leaves) and for its carbon stored. For the aboveground biomass D. asper obtained the highest (264.37 ton/ha) followed by B. philippinensis (48.29 ton/ha) and S. lumampao (34.49 ton/ha). The mean organic carbon content of the aboveground biomass was determined which had a range value from 52.09-54.24%. The data revealed that culms comprised the highest aboveground carbon yield (64.06-84.37%). Generally, the total carbon stock of D. asper (234.46 ton/ha) was higher compared to B. philippinensis (149.87 ton/ha) and S. lumampao (63.55 ton/ha). D. asper obtained the highest carbon stock in the aboveground (143.39 ton C/ha) which was 61.16% of the total, followed by soil (57.52 ton C/ha) 24.53% and belowground (33.55 ton C/ha) 14.31%. While both the B. philippinensis and S. lumapao, the carbon stored in soil yielded the highest percentage which were (118.19 ton C/ha) 78.86% and (41.22 ton C/ha) 64.86% respectively, followed by aboveground (17.05-28.26%) and lastly, belowground (4.09-6.89%). In these findings, it was D. asper showed a greater capacity to store more carbon, hence a good mitigation strategy for global warming.
