We researched and calculated the percentage of wood that is wasted at the forest and the lumber mill. We measured the energy used at these two locations and the lumber market. We also calculated the amount of CO2 emissions from energy consumption at these three locations and in the transporting of the wood.
The following results were obtained.
1) The embodied CO2 of northern Nagano Japanese cedar and eastern Nagano Japanese larch were 241.37kg-CO2/m3 and 254.53kg-CO2/m3 respectively.
2) The CO2 emissions from the construction of the house that was made from local wood could reduce CO2 emissions by 39%, compared to the construction of the house that was made from imported wood.
