Abstract
We calculated the Carbon Footprint of Products (CFP) of lumber locally produced for local consumption and manufactured by six types of sawmills. First, we calculated and compared CFPs of lumber with and without the kiln-drying process, and we obtained the average of CFP for lumber certified by Kyoto prefecture. Then, we studied the effect of differences in the process on CFPs based on the calculated results. Accordingly, “The rate of kiln-dried lumber”, “The heat source of the kiln-drying process” and “Transport processes of logs and of lumber products” respectively made impacts on CFP for lumber certified by Kyoto prefecture, and countermeasures for reducing CFP differed depending on the scale and/or manufacturing process of sawmills.
