Agricultural activities have resulted in environmental impacts, mainly because it is one of the sectors that emit the most Greenhouse Gases (GHG). Agriculture based on the practice and principles of Agroecology strengthens relations with the Environment and presents itself as an alternative to reverse global warming and climate change. Therefore, this study aimed to analyze carbon sequestration in family agroecosystems. Nine family farms in agroecological transition, located in the Agreste Meridional region of Pernambuco, were evaluated. The data were obtained from a field study, as well as through image analysis of the Google Earth software. In this way, the size of agricultural properties and crops was verified. In turn, the trees and shrubs were quantified and also classified according to their size. Information on the frequency and quantity of inputs was also taken into account. The estimated annual carbon sequestration value in kilograms of carbon dioxide (CO2) was calculated using the Positive Climate Design digital platform. Subsequently, the efficiency of CO2 sequestration was calculated. From the results obtained, it was observed that the properties have a relevant capacity in carbon sequestration. Activities such as soil management, plant diversity, crop rotation and natural control of pests, diseases and spontaneous herbs collaborated with the Carbon Footprint in these properties. In addition, such systems can contribute to the GHG reduction targets set by the country, thus valuing the land and its products.
