The objective of this study was to generate equations to estimate carbon in trees of the main campus of Universidade Federal de Viçosa, contributing to the knowledge about the ability of urban green areas in removing and storing carbon. Thus, every tree with DBH less than 5 cm located at the university was inventoried. For no palm trees, were selected 721 sample trees, which were rigorously cubed by successive application of Smalian expression until 5 cm of diameter, for trunk and twigs. Regarding the palm trees, 100% of the individuals were cubed using the Huber expression. The basic density of wood with bark and content carbon were obtained, in palm trees, by removing a disk on DBH, due to the difficult of borehole. For the other trees, a mechanical auger was used. Based on the volume with bark, the basic density and carbon content, we calculated the total carbon and carbon in the twigs. Furthermore, we evaluated the Schumacher & Hall (1933) and Spurr (1952) modified models to estimate the carbon fixed in these individuals. In the case of no palm trees, the total carbon and the branches carbon can be estimated, in kg, according to the Diameter at Breast Height (DBH in cm) and Total Height (TH, in meters), by -0,906586+1,60421*LnDAP+0,37162*LnHt e por -2,052673+1,89903*LnDAP+0,24156*LnHt, in this order. In palms, the total carbon can be estimated by -4,46988+199082*LnDBH+1,06420*LnTH.
