Abstract
Aiming for a sustainable society is one of the most important missions in the first half of the twenty-first century. In the civil engineering field, which normally focuses on carbon dioxide emissions, other techniques to attain a perfect sustainable ecosystem are considered expectable. For this, technical developments are needed to harmonize natural ecosystems for the reduction of carbon dioxide emissions or reduce carbon dioxide from the atmosphere. The authors propose using a lot of wood in the civil engineering field. However, civil engineers do not have the chance to learn about wood science and some engineers have misconceptions about the use of wood. For these reasons, this paper explains the significance of using wood for a sustainable society. As a concrete measure, the authors proposed the use of wood as a countermeasure against poor, unstable ground and liquefiable ground.
