Climate change is the challenge provided with the most attention within all circles in the 21 st century. This phenomenon allegedly originates due to the increasing concentrations of CO 2 gas in the atmosphere. Therefore, efforts are continually designed to slow down or halt the process to avoid significantly impacting life on earth. The common mitigation approach is by encouraging the planting of trees to optimize CO 2 sequestration. This study, therefore, aimed to determine the CO 2 sequestration capacity of Aquilaria malaccensis in natural forests and plantations. Particularly, Aquilaria malaccensis is an endemic plant of Indonesia’s tropical forests, with critical or endangered status. The allometric method was adopted, with purposive and non-destructive sampling techniques, then a multilevel plot was used during CO 2 sequestration analysis. This plant species absorbed the gas at the tree category in natural forests (9.57 tons CO 2 eq/year), and similarly with plantation forests (2.35 tons CO 2 eq/year). The tree biomass category in natural forests (5.22 tons CO 2 eq/year), and plantations (1.28 tons CO 2 eq/year), alongside the pole category in natural forests (1.9 x 10 -3 tons CO 2 eq/year) rank lowest. The carbon content in the tree category ranked highest at the natural (2.61 tons CO 2 eq/year), compared to plantation forests (0.64 tons CO 2 eq/year), while the carbon composition in pole category at the natural and plantation forests were (9.8 x 10 -4 tons CO 2 eq/year) and (2.2 x 10 -3 tons CO 2 eq/year), respectively.
