This application calculates seven types of environmental impacts (resource footprint, environmental footprint, ozone layer impact, acid rain, eutrophication, photochemical smog, and water footprint) when users enter the quantities of inputs and outputs (including by-products) in the production process of products and services. It is a tool that expresses numbers and graphs and was developed as an industry-academia project between ‘Donut Soft Co., Ltd.’ and ‘Chungbuk National University Smart Ecological Industry Convergence Graduate School.’”
