035R_Review of sustainability indices and indicators: Towards a new City Sustainability Index (research summary)

Summary of the article titled Review of sustainability indices and indicators: Towards a new City Sustainability Index from 2012 by Koichiro Mori and Aris Christodoulou published in the Environmental Impact Assessment Review journal.  Since we are investigating the future of cities, I thought it would be interesting to see how the different sustainability indices work and whether a new is needed to better assess urban sustainability. This article investigates whether a new sustainability index is needed, enabling to assess and compare cites’ sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution.

Abstract: The purpose of this paper is to discuss conceptual requirements for a City Sustainability Index (CSI) and to review existing major sustainability indices/indicators in terms of the requirements. The following indices are reviewed: Ecological Footprint (EF), Environmental Sustainability Index (ESI), Dashboard of Sustainability (DS), Welfare Index, Genuine Progress Indicator (GPI), Index of Sustainable Economic Welfare, City Development Index, emergy/exergy, Human Development Index (HDI), Environmental Vulnerability Index (EVI), Environmental Policy Index (EPI), Living Planet Index (LPI), Environmentally-adjusted Domestic Product (EDP), Genuine Saving (GS), and some applications of composite indices or/and multivariate indicators to local or regional context as case studies. The key conceptual requirements for an adequate CSI are: (i) to consider environmental, economic and social aspects (the triple bottom line of sustainability) from the viewpoint of strong sustainability; (ii) to capture external impacts (leakage effects) of city on other areas beyond the city boundaries particularly in terms of environmental aspects; (iii) to create indices/indicators originally for the purpose of assessing city sustainability; and (iv) to be able to assess world cities in both developed and developing countries using common axes of evaluation. Based on the review, we conclude that it is necessary to create a new CSI that enables us to assess and compare cities' sustainability performance in order to understand the global impact of cities on the environment and human life as compared with their economic contribution. In the future, the CSI will be able to provide local authorities with guidance toward sustainable paths. The transcript is available through this link. What wast the most interesting part for you?
