Planted forests stand out in the context of the mitigation of greenhouse gases, as they are renewable stocks that give continuity to carbon stocks. The objective was to quantify the stock of biomass and carbon in the aerial part in a commercial plantation of paricá (Schizolobium parahyba var. amazonicum). Trees distributed in five diameter at breast height (DBH) classes were selected, defined by the forest inventory. The trees were felled and the trunk, bark, branches and leaves were separated. For basic density, the highest values ​​were found in DBH classes between 19.4 and 28.2 cm (380 kg m-3 and 345 kg m-3). The plantation accumulated 41.94 Mg ha-1 of biomass and the intermediate classes (10.6 to 19.4 cm) represented 84% of the total biomass. Regarding the compartments, it was observed that both the biomass and the accumulated carbon content increased in the following order: stem > branch > leaf > bark. The biomass stored in the stem represented 72.2% of the total estimated for planting. The total carbon stock found for the stand was 16.6 Mg ha-1. The paricá plantation showed considerable accumulations of biomass and carbon. The cultivation of paricá can contribute to carbon credit programs.
