Fundamental study on carbon neutral society construction considering sustainable forest resource circulation

We investigated the forest management procedure which can assimilate much amount of CO_2 continuously in the planted forest in Japan. We also evaluated forest economically considering the carbon assimilation capacity and we would be able to confirm the forest management procedure whose amount of annual average CO_2 assimilation became nearly 6% of domestic CO_2 emission in 1990. On the other hand, on the condition that assimilated CO_2 through forest management procedure can be traded in the future domestic emissions trading market, the balance of forest management income and expenditure including emissions-rights sale profits is indicated to be equivalent to the balance on silviculture subsidy, or more profitable than that. Furthermore, forest management could be found to cost less than 1/15 of the marginal abatement costs in other CO_2 reduction measures, such as energy saving.
