Land use change, particularly deforestation in tropical regions, is the third largest source of greenhouse gas emissions. Areas in process of forest restoration are important tools for mitigating climate change, as carbon is sequestrated from tree growth and consequent accumulated in biomass. Thus, studies are needed to quantify these ecosystem services in ecological restorations, considering different environmental variations in the landscape. With this, the general objective of this work aims to estimate the potential for providing ecosystem services for climate regulation and financial gains from carbon credits in areas undergoing restoration. This study was divided into three chapters, the first, is a literature review carried out on how carbon storage monitoring in forest restorations occurs, in order to detect trends, indicators used, and the main demands and challenges of the studies. In the second part, the potential of different land uses to mitigate climate change was investigated, through the quantification of the carbon stock in different compartments in landscapes in the Atlantic Forest. Finally, the third chapter, with a more social and economic nature, aimed to estimate the environmental and financial gain that can be obtained by paying landowners for the environmental service of carbon sequestration in forest restoration in Permanent Preservation Areas (PPA). It may contribute to the identification of effective strategies for environmental restoration of PPA and to encourage the adoption of these measures by rural landowners, with benefits both for the environment and for the local economy. The results of these theses present the carbon stock in forest restorations under different paths, and can be used for future scientific research as well as in decision-making in the formulation and implementation of public policies, in line with global strategies for mitigating climate change
