Quantification of carbon stock and economic evaluation of management alternatives in a eucalypt plantation

The objectives of this study were: to quantify the wood stock for coal production and for sawmill in an eucalypt stand;) to quantify the carbon stock in the various compartments of the forest; and to evaluate economically management alternatives in order to include forest stands in the Clean Development Mechanism and in the sale of the carbon credits. In order to do so, a forest inventory in a 6-year-old plantation of Eucalyptus grandis, located in Viçosa, Minas Gerais State, Brazil, was carried out. The analysis showed that: a) the stem is a tree component that contributes the most, in average, for total carbon of the aerial part (81.84%), followed by the bark (8.05%), branches (7.74%), and leaves (2.57%); b) 47.7 tons of the carbon per hectare are stocked in the aerial parts of the trees; 14.71 tons in the roots; and 8.72 tons in the organic litter; totaling 71.13 tons of carbon per hectare; c) the wood production for the sale of carbon credits only, without considering its final use, is economically feasible, according to quantitative criteria of the project evaluation, if the ton of carbon was commercialized at prices higher than US$ 10.07; d) the sale of the carbon credits makes the activity even more attractive economically, mainly because the income enters at the beginning of the project.
