In this study, the environmental improvement effectiveness of CCU(Carbon capture & utilization) technology is analyzed, based on LCA(Life cycle assessment) methodology. Target CCU technology is synthesis process which uses carbon dioxide as raw material and produces useful materials such as DMC(Dimethyl carbonate), methanol and etc. As a result of LCA performed, 25 g CO2 eq. of greenhouse gases is reduced during life cycle for treating 1 kg of carbon dioxide. Therefore, target CCU technology produces an effect on greenhouse gas reduction. And electricity consumption of synthesis process is the main issue of GWP results. The improvement of energy type of synthesis process is effective for GWP. 746 g CO2 eq. of greenhouse gases is reduced by changing energy type of synthesis process. As a result, life cycle GWP reduction is obtained. The scenario analysis about carbon dioxide transportation distance is performed. In case of the distance of carbon dioxide transportation is farther than 97.13 km, the amount of greenhouse gas emission during life cycle is larger than avoid and target CCU technology is ineffective for greenhouse gas reduction. Consequentially, target CCU technology is effective for greenhouse gas reduction. And the region for installing the process should consider the distance of carbon dioxide transportation.
