저탄소 생수제품의 탄소배출량 감축효과 분석

The global efforts to respond to climate change by reducing greenhouse gas were accelerated, as negative effects of climate change have been visualized and its direct damages to economy have been realized. Korea's Carbon Footprint Labeling get a lot of attention as one of the effective methods to contribute to national GHG reduction goal, and for enterprises to show customers how much effort the company put into global warming prevention. Consumers' interest on low-carbon products has been increasing. This study uses Life Cycle Assessment (LCA) method to calculate the amount of carbon emission of PET-bottled water, which reduced carbon emissions by using high efficiency manufacturing techniques. LCA Method is based on guidelines of Carbon Footprint Labeling, Korea government, and pre-manufacturing, manufacturing, and disposal steps are included while use step of the product is excluded from this method. In order to understand the effects of eco-design on carbon emissions, the PET-bottled water’s carbon emissions are compared before and after the change of manufacturing techniques. The result shows the improvement from 94.0 gCO₂-eq/EA to 86.7 gCO₂-eq/EA, and this means carbon emissions has been reduced by 8.4%, which is equivalent to 272tons of GHG emissions a year.
