Definition of the initial capital value in reforestation processes with negative co2 emissions

Negative CO2 emission processes are techniques that involve the definitive removal of excess CO2 from the atmosphere. Advances in the method of carbon quantification in reforestation have allowed the accomplishment of mathematical-statistical modeling as a function of production and productivity in the carbon storage processes of structured reforestation programs. This work aimed to investigate a method that allows the quantification of the initial capital in a process of greenhouse effect mitigation through reforestation. The materials used consisted of the production and productivity equations in a productive structure under sustained yield management of Mimosa scabrella Benthan, commonly known as Bracatinga. The results show that the rate of capitalization or discount of natural values follows a sigmoidal form, not a non-geometric form. Interest rates must be derived and appropriated in the actual process or production effect. By obtaining the current present value of production and the variable interest rate, one can calculate the initial capital of the period considered. The possibility of calculating the variable interest rates also allows the same process to be applied in the management of native populations under a polycyclic sustainable income system.
