How to calculate CO2 sequestration

To calculate the tree''s dry weight, we could multiply the total weight of the tree by 72.5%. Total Dry Weight (TDW) = TB × 0.725. Carbon occupies 50% of the total dry weight. Therefore, Total Carbon (TC) = TDW × 0.5. With the value of total carbon, we can calculate the value of CO 2 equivalent sequestered on a tree.
