Abstract
The purpose of this paper was to calculate the unit cost of J-VER certification by summing up labors and monetary costs consumed in the removal by forest sinks accelerated thinning project in The University of Tokyo Chiba Forest. In addition, sales price of J-VER was discussed by considering the standard case of thinning project. In the case of Chiba forest, the unit cost of J-VER certification was 3,606 yen/t-CO2 for 1,614 t-CO2 credits summing up validation and verification fees, labor costs for J-VER related work and thinning fees altogether. Adjusting each cost of Chiba forest project compared with common cases of registered and certified thinning projects in terms of thinning areas, monetary costs, amounts of credit, etc., the unit cost of J-VER certification was estimated about 4,700 yen/t-CO2 at most in the standard case of 5 year credit period, thinning area of 100 ha and credits of 1,600 t-CO2. If all of the 1,600 t-CO2 credits were sold for the unit price of around 4,500yen/t-CO2, which was the recent indicative price of removal by forest sinks project by buyers, validation and verification fees, labor costs for J-VER related work and thinning fees for a couple of years were considered to be covered.
