Abstract:
This paper described the potential of the carbon balance of combined projects with forest management and wood product use including bio-energy. We developed a model to quantify carbon stock, fluxes and emission reductions. Using this model, we calculated how the carbon balance was affected by additional activities concerning forest management and wood product use including bio-energy. We estimated the net carbon balance in the different project scenarios. The results of this study lend to the conclusion that combined projects would be beneficial to net carbon balance that depended on the implementation of forest management and wood product use. 1) Under the higher implementation rate of thinning could be a negative factor to the net carbon balance in the short term; although it is not the case in the long term. It also in creases emission reductions by bio-energy utilization. 2) Under leaving harvested woods in forests is mo it could contribute to the unstable supply of harvested woods as raw material for bio-energy.
