하위흐름을 포함한 전과정에서의 국산 사과 탄소발자국 산정

Abstract

This is a preliminary study for development of a national LCI Database that should be established to reduce greenhouse gas emissions in the agricultural sector, and that considers distributions, use, and disposal stages, which were limited in evaluation due to the absence of data that guarantee representatives. The subjects of the study were apples, and the life cycle assessment was conducted under the assumption of fresh food (agricultural products processed products). Especially considering the difference in distribution process form production to consumer, the production regions were calculated separately in Gyeongsangbuk-do (Yeongju, Andong, Uiseong) and Chungcheongbuk-do (Cheongju). Accordingly, the result shows that the distribution phase has the largest impact on the life cycle for the apple. Since it is difficult to clearly measure the transport distance of the distribution stage, the carrying cost in the distribution process was used as indirect data, and the disposal stage was calculated by setting a scenario in consideration of apple peels, etc. The results of this study are intended to be used as an example of calculating GHG emissions for downstream processes of domestic agricultural products, prior to estimating and regulating the carbon footprint of imported agricultural products in line with the global issue of imposing carbon tax on imported goods between countries.
