Global urbanization imposes a burden on limited resources, with more than half of the world's population expected to live in cities by 2050, resulting in massive deforestation and environmental challenges. In this context, urban green spaces (UGSs) emerge as essential elements for promoting sustainability. UGSs encounter challenges in terms of land availability, quality, and distribution. Overcoming these obstacles necessitates the development of a sustainable framework, the exploration of planning techniques, and indicators for assessing UGS and its management practices that support sustainability. This paper tries to understand the UGS concept through its linkage with sustainability and, its benefits to achieve sustainable development goals. It studies indicators under the three dimensions of sustainability to obtain a comprehensive view of indicators studied globally across the urban planning domain. Forty peer-reviewed journal papers on the UGS are studied to understand their assessment methodology and indicator framework. The indicators are categorized under three sustainable pillars: a) environment; b) economic; and c) socio-cultural. The indicators were shortlisted after removing duplication and were further analyzed at three different scales of study. The results reveal a diverse set of priorities among regional, city, and neighborhood scales and majorly periodizing environment criteria indicators. The study develops a framework using selected indicators for UGS sustainability assessment. The framework guides urban planners in creating successful green space development, ensuring optimal distribution and access to UGS.
