Areas destined for conservation play an essential role in global climate regulation, as forests are the main terrestrial carbon sink, since they capture carbon dioxide from the atmosphere and store carbon in their biomass, mainly in wood. The objective of this work was to analyze the dynamics in volume, biomass and carbon stocks in the total area of the Iguaçu River Basin and in special areas, such as Riparian Forests, Conservation Units, Indigenous Lands and Rural Settlements, between the years 2000 and 2015 Vector files of the basin's forest cover for the base years were used to estimate the variables by forest formation and successional stage. The Iguaçu River Basin as a whole acted as a carbon sink over the analyzed 15-year period, with an increase in stocks of approximately 14% for V, AGB, C, and CO2eq (sequestering 116,173,629.91 tons of CO2eq). The special areas acted as carbon sinks, with Conservation Units storing the most carbon (11.72% of the total watershed), and Riparian Forests sequestering the most carbon (3.54% of the total watershed).
