Abstract
We compare the CO2-emission between wood retaining-wall and concrete retaining-wall. The size of the retaining-wall is 2.0 meters high and 100 meters long. And we analysis the characteristics of CO2-emission between wood retaining-wall and the concrete retaining-wall. Then we get the following results: 1) The wood retaining-wall made of local material have a smaller quantity of CO2-emission of material compared with concrete retaining-wall, because the process of making wood retaining-wall is simpler than the concrete. 2) In the process of the construction, CO2-emission of wood retaining-wall have a 1/6 quantity of the concrete. 3) From the viewpoint of LC CO2, 9 year-old wood retaining-wall have the same quantity of “CO2-emission as 50 year old concrete retaining-wall”.
