This paper focuses on how to reduce CO2 emissions regarding construction materials. We compared section by section the amount of CO2 emissions from the four different houses. Next, we made an improved plan that took away the first floor that was constructed with reinforced concrete, as well as the interior decorations which emitted less CO2 during their factory production. The following results were obtained.1) We determined which sections of the four houses had less construction waste. We determined which sections of the four houses emitted less CO2 during their production.2) The total amount of CO2 emissions per floor from construction materials is 318.8kg-CO2/m2~498.1kg-CO2/m2.3) The proposed countermeasure that took away the first floor reduced CO2 emissions by 15.7×103kg-CO2, a decrease of 30.4%.The proposed countermeasure that used the interior decorations, which emitted less CO2 during their factory production, reduced CO2 emissions by 5.1×103kg-CO2, a decrease of 9.9%.The countermeasure that the authors described in their improved plan reduced CO2 emissions by 20.8×103kg-CO2, a decrease of 40.3%.
