Assessment of Sustainability for Small Municipalities

Abstract

A method for assessing sustainability of local regions and small municipalities is presented. Such a tool is needed as decisions made at the local level can have significant effects on the sustainability of a region when applied to multiple small municipalities. Quantitative and objective measures for evaluating regional sustainability should provide guidance and direction for improvement, and should help direct public policy. The ecological footprint method distills a complex system into a single parameter — the land area required to support the region under study. While this method provides a metric that is easily understood by both the public and policy makers, it is difficult to apply on the scale of many local municipalities. The method gives an overall indication of a region’s sustainability, but it can be difficult to determine specific actions that will lead to improvement, and hence has limited value as a guide to policy. The emergy accounting method is scalable and can indicate specific areas needing improvement. All energy flows are transformed into a common unit, the solar emjoule, allowing equitable assessment of sustainability within a system comprised of a broad spectrum of human, natural, and industrial resources and processes. Obtaining data for a study of any scale can be challenging; however, it is particularly so for small regions in which data may not be readily available. Adjustments in data collection methods appropriate to small regions and municipalities are evaluated. The adjusted method was applied to the analysis of a small rural municipality in western Pennsylvania. The study boundaries were defined by the borough limits — an area encompassing 2.7 square miles and 8300 residents. This study primarily treats data collection for an emergy accounting analysis of a small region. Full results of the analysis will be presented in a follow-up paper.
