A REPORT ON SOME URBAN SUSTAINABILITY INDICATORS PRACTICED IN THE WORLD

Abstract

21st century is the century of the city. It is estimated that more than half of the world's population already lives in cities, and that percentage is projected to increase further. While cities provide huge opportunities for economic development, they also pose mounting problems to the global ecosystem and human sustainability. Urban indicators are crucial to help local and national policymakers improve their action towards sustainability. Research on the sustainable city and its evaluation indicators have been accumulated in the past decades. However, there are not many reports on how they are implemented. This paper introduces some urban sustainability indicators practiced in the world in order to provide the background information for further research on the methodology of building sustainability indicators that are practicable to a certain locality.
