The increase in carbon dioxide (CO2) implies the intensification of the greenhouse effect, since from a quantitative point of view it is the most responsible for the process. The result of this effect is the disturbance of the energy balance between the earth and the atmosphere, causing climate change on the planet. There is the possibility of reducing greenhouse gas emissions to the atmosphere through planting with forest species, combined with sustainable reforestation and afforestation techniques in areas that have suffered human disturbance. In this context, our goal is to evaluate the potential for carbon sequestration and fixation in three forest fragments in the Tottori friendship forest in the City of São Paulo at eight years of age for 33 forest species. The species were grouped into four distinct groups, with distinct main characteristics. However, it was observed that 28 from 35 species do not present an outstanding characteristic for the grouping. The other seven species stood out for presenting dendrometric characteristics with carbon sequestration and fixation, specifically Clitoria faichirdina and Samanea saman. Among the characteristics that are most related to carbon sequestration and fixation were DBH, Stem volume and total volume, wood density was the characteristic that was least correlated with the others evaluated. It is recommended that an assessment be carried out at older ages to verify whether the grouping and values of carbon sequestration and fixation change over time, and possibly explain how the botanical family of a given species can influence carbon sequestration and fixation and plantations of forest fragments.
