The sequestration of carbon and its stock of above-ground plant biomass contributes to reducing the greenhouse effect and consequent global warming where the conservation of private forests through the creation of conservation units must guarantee their owners some compensation for the environmental services produced, including the carbon sequestration and its stock in forest biomass. This work aimed to quantify the biomass and carbon stocks of RPPN Não Me Deixes, Quixadá, Ceará. The estimation of the carbon stock can assist in the economic evaluation of the environmental services provided by this and other categories of conservation units. The Private Reserve area of the Patrimonio Natural Fazenda Não - Me - Deixes located in Quixadá in the state of Ceará was studied. The biomass and carbon stocks of tree vegetation in the RPPN area, which is a Conservation Unit, were determined. The determination of biomass in these areas was measured using allometric equations, since it would not be technically and legally feasible to use the destructive method. The conversion of biomass to carbon took place by adopting a factor of 0.5 and the accounting for carbon credits was generated by a factor of 3.67. The study of tree vegetation indicated a total of 2311 individuals, belonging to 31 species and 12 botanical families. In the RPPN area, the estimated biomass was equal to 38,502.00 tons of biomass above ground, which corresponds to a carbon stock of 19,251.00 t - C ha-1 for the 300 hectares of UC. In the vegetation, the species known as marmeleiro, jurema - preta, caatingueira, cumaru and pereiro predominated. The estimate for biomass and carbon of the RPPN contained in the Caatinga was very good in relation to forests in other biomes in Brazil, as it ended up generating similar or better results than preserved forests in other biomes. As a result, it is important to carry out these studies to prove that the Caatinga acted as a CO2 sink, even suffering from periods of extreme drought and human interference, it becomes an important ally in the realization of this ecosystem service of carbon fixation and storage in a meaningful way. it is important to highlight the services provided by Caatinga, mainly in the areas of preservation of the Biome, such as the RPPN, which multiplies the capacity to store and sequester carbon from the atmosphere because it is preserved.
