ICT support of smart cities development

Abstract

This thesis investigates the contribution of Information and Communication Technologies (ICT) to the development of smart cities, with a specific emphasis on environmental sustainability. The study examines how digital technologies, such as the Internet of Things (IoT), digital twins, and big data analytics, are applied in managing core urban systems, including energy, waste, water, and transportation. The analysis is based on seven international cities , Singapore, Amsterdam, Copenhagen, Oslo, Zurich, Dubai, and Cape Town, which have demonstrated significant progress in integrating ICT into environmental governance frameworks. The study adopts a qualitative multi-case design, structured around five analytical dimensions: environmental performance, technological innovation, digital governance, contextual adaptability, and long-term sustainability. Results highlight ICT's role in promoting efficient use of resources and enhancing civic participation. At the same time, the analysis points to existing barriers, such as rising energy demands, unequal access to technology, and regulatory shortcomings. The thesis offers practical suggestions to support more effective, inclusive, and environmentally driven digital transformation in urban contexts.
