Carbon economic valuation of the <i>Diospyros minahassae</i> stand at the Kawanua Arboretum in Manado

Abstract As we get closer to 2030, which is the deadline for achieving Indonesia’s National Determined Contribution (NDC) target, coupled with plans to implement a carbon tax, there are opportunities for utilizing vegetation that has high sequestration capacity. One of them is the Diospyros minahassae species, which is an endemic species to the Wallacea region that has the ability to absorb carbon. This research aims to calculate the carbon absorption potential and economic valuation of the Diospyros minahassae species so as to obtain an overview of its benefits and contribution to achieving NDC targets both regionally and nationally. The carbon uptake potential of the Diospyros minahassae species was calculated using the allometric equation and then converted into a carbon uptake value. This carbon absorption value is then calculated as potential income based on the carbon sales value set by the World Bank. Based on the calculation results, it was found that the potential for carbon uptake in the Diospyros minahassae species reached 69,491 tons/ha or the equivalent of 138,983 USD/ha.
