In Japan, introducing biomass based polyethylene (bio-PE) is expected to be one of the effective measures to achieve the target to reduce GHG emissions by 26% by 2030 compared to 2013. We investigate the current GHG emission related to shopping bags utilization and the reduction effect by replacement of bio-PE under two different scenarios.The GHG reduction potential of improving separation and bio-PE replacement of shopping bags was estimated. Scenario assessment proved that both improving separation ratio and bio-PE replacement ratio reduces GHG emission from the viewpoint of life cycle. Bio-PE replacement would reduce GHG emission by 76.1% compared with the baseline scenario. If bio-PE replacement were introduced, 800 kt CO2 eq. of annual GHG reduction would be expected in Japan. Further 66 kt CO2 eq. may be achieved if the separation ratio catches the general plastic packaging and containers. As this analysis based on 100% bio-PE replacement as potential, actual blending ratio will need to be considered.
