This paper presents a comprehensive and interdisciplinary literature review on smart sustainable cities, highlighting the challenges, opportunities, and future directions in this field. The concept of smart sustainable cities has gained significant attention as a response to the challenges of urban sustainability, particularly in ecologically and technologically advanced nations. The paper reviews existing sustainable city models and smart city approaches, discussing their strengths and weaknesses in relation to the goals of sustainable development. It identifies critical issues that remain unsettled, less explored, and theoretically underdeveloped for applied purposes. The paper also highlights the need for a theoretically and practically novel model of smart sustainable urban form to address the key limitations, uncertainties, paradoxes, and fallacies in existing models. The paper emphasizes the role of ICT, big data analytics, and context-aware computing in advancing smart sustainable urban planning and development. It argues that the integration of these technologies can help overcome the challenges of urbanization, improve urban sustainability, and enhance the quality of life for citizens. The paper also discusses the importance of interdisciplinary research and collaboration in addressing the complex challenges of urban sustainability. It concludes that the applied theoretical inquiry into smart sustainable cities is of high relevance and importance, given the early stage of research in this field and the practical applications of contemporary theories. The paper provides a valuable reference for researchers and practitioners in related fields, offering insights into the latest developments in smart sustainable urban planning and development. The proposed integrated approach is believed to be the first of its kind and has not been produced elsewhere. The paper also highlights the need for further research and development in this area, emphasizing the importance of linking ICT development with sustainable development to justify future investments based on environmental concerns and socio-economic needs. The paper underscores the importance of interdisciplinary collaboration and the need for innovative solutions to address the challenges of urban sustainability. It concludes that the integration of smart technologies and sustainable development principles is essential for achieving the long-term goals of urban sustainability.This paper presents a comprehensive and interdisciplinary literature review on smart sustainable cities, highlighting the challenges, opportunities, and future directions in this field.
