Abstract

While some of the plastic shopping bags given out to customers by shops are disposed of after a single use, others are reused as trash bags in municipalities where designated trash bags have not been introduced. In addition, discontinuation of plastic shopping bags has an influence on recycling of plastic containers and packaging in municipalities where recycling collection of plastics waste is implemented. The effect of stopping distribution of plastic shopping bags by retailers also depends on how waste management policies are implemented in the municipalities where retailers are located. This paper presents how stopping distribution of plastic shopping bags at shops can effect greenhouse gas reduction, evaluated using life cycle assessment that looks at differences in the indirect effects of municipal waste management policies. Results showed that regardless of the municipality, there were almost similar effects, when stopping distribution of plastic shopping bags was assumed to influence on only their life cycles. The effects were shown to be less in municipalities where plastic shopping bags had been reused or recycled, when stopping distribution of plastic shopping bags was assumed to influence on not only their life cycles but also that of other products as well.
