Proposing an Indicator System for Measuring City Sustainability

An increasingly rapidly urbanising world highlights sustainable urban development as an inevitable crucial issue that has recently been at the forefront of numerous scientific inquiries. Measuring city sustainability contributing to the quality of urbanisation is a substantial research field in this area. Meanwhile, a comprehensive functional indicator system, including accurate indicators, is the first point of measuring city sustainability. Hence, this paper aims to propose an indicator system for measuring city sustainability by analysing current research and experiences, including existing frameworks, indicator systems, and case studies. Through a systematic literature review of articles published by Elsevierand MDPI from 2019 onwards, an indicator system has been developed that could be applied for measuring city sustainability according to available and accessible data. It includes the 21 most frequent indicators based on the three main subsystems of economy, society, and environment. Concerning their effects on city sustainability, they were categorised into two properties of benefit and cost regarding the sustainable development of a city. Thus, seven indicators measure the economic dimension, sevenconsider the social dimension, and seven address the environmental dimension. Conducting empirical case studies following the proposed indicator system accompanied by weighting approaches and aggregating methods as another significant issue concerning measuring city sustainability will complement the current path to future further research
