                Consequently, carbon economics and carbon crediting mechanisms offer
              important tools to reduce carbon emissions and enhance ecosystem services.
              In Türkiye, the economic value and social benefits of these approaches have
              started to be evaluated in line with sustainability criteria.


                3.5. Calculation Methodology in Carbon Economics

                In  carbon  economics,  the  financial  value  of  carbon  is  calculated  using
              parameters such as the amount of carbon in dry biomass, the amount of CO₂
              sequestered and the price of carbon, based on the vegetation pattern of
              sinks and field data. Using the photosynthesis equation, the amount of CO₂
              sequestered by biomass is calculated metrically (Laposata, M. and Pratte, J.
              2005). With this calculation, the amount of CO₂ sequestered in 1 kilogram of
              wood mass was found as 1.65 kg. However, in order to calculate the present
              economic value of carbon, the net present value of CO₂ sequestered from
              planting or transplanting is calculated, taking into account parameters such
              as interest rate, rotation period and carbon price.
                Furthermore,  the  amount  of  CO2  sequestered  by  biomass  is  calculated
              metrically with the help of Equation 1, which is derived from the photosynthesis
              equation (Laposata, M. and Pratte, J. 2005).
