This study describes the environmental impacts of lumber for building construction in Japan, focusing on CO2 emission. First, we collected the inventory data of several patterns of lumber with domestically-made or foreign-made using a case study approach based on some fieldworks.
Second, we tried to estimate the volume of each and total CO2 emissions. Finally, we analyzed the issue of estimating method. According to the results, the patterns show obvious differences especially in transportation phase and kiln-drying phase. In addition, the emission coefficients have big influence on the results.
