Abstract
Abstract The componential method of ecological footprint is applied to estimate the ecological footprint of Northeastern University (NEU) in 2003. The components considered in this study include energy (coal, natural gas, and electricity) consumption, food consumption, waste disposal, water supply, transportation, and paper consumption. The ecological footprint of NEU was 24,787 ha, meaning that nearly 25,000 ha of ecologically productive lands were needed to support consumptions and wastes disposal. The largest component of ecological footprint was energy consumption, which took up 68% of the total footprint; the second and the third largest footprint components were food consumption and waste disposal. In a word, ecological footprint can serve as a practical and meaningful tool for comparing and monitoring the environmental impact of campuses.
