Abstract: The implementation of Smart Sustainable City (SSC) solutions provided an answer to the many urban problems and challenges caused by rapid urbanisation, environmental degradation, and extensive economic global competition. The Kingdom of Bahrain strives to achieve its sustainable development goals by adapting Information and Communication Technologies (ICTs). However, the initiatives undertaken by the Kingdom of Bahrain lack a schematic framework for the development and assessment of SSCs solutions. This research aims to analyse and define a SSC in the local context of the Kingdom of Bahrain. It further seeks to develop an assessment framework suitable for evaluating SSCs in Bahrain. The study also validates the developed measurement framework by assessing the quality of urban life in Diyar Al Muharraq, a newly developed urban area in the Kingdom of Bahrain selected for its goals of creating a smart and sustainable urban environment. The research was conducted in three stages using a mixed-methods approach. First, the meaning of SSCs in the local context of the Kingdom of Bahrain was articulated by deriving keywords from the literature review. The keywords were mapped against the policies and national goals of the Kingdom of Bahrain to develop a local definition. Second, the definition obtained in the first stage of the research served as a guideline for identifying the Key Performance Indicators (KPIs) suitable for the local context of the Kingdom of Bahrain. Third, the selected KPIs were then used to evaluate the urban quality of life in Diyar A1 Muharraq. The local definition of a SSC that this study outlines highlighted the prime principles for developing SSCs locally to enhance the quality of urban life. The research also identified a KPIs framework that can be used to analyse an urban environment in the Kingdom of Bahrain. The urban evaluation of Diyar Al Muharraq validated the selected KPIs. This study is an initial step that contributes to understanding SSCs in the Kingdom of Bahrain. Future studies can test the methodology proposed in this research by using it to evaluate the quality of urban life elsewhere.
