Despite the consideration of alternative energy resources and increasing the energy efficiency in the systems to decrease the amount of CO2 emissions, the cumulative rate of CO2 in the atmosphere needs to be decreased to limit the detrimental effects of climate change. Therefore, regardless of the extension of clean and more efficient energy systems, carbon-removing technologies need to be implemented. Carbon Capture, Utilization, and Storage (CCUS) is a novel technology that captures CO2 from facilities including power plants, the transportation systems, and industrial sectors. The CCUS technologies can deliver ‘negative emissions’ by removing CO2 directly from the atmosphere or from biomass-based energy and storing the CO2. Therefore, CCUS technologies need to be implemented in the smart sustainable cities. This book is an attempt to bring together the experts from the different disciplines related to carbon capture, utilization, and storage process and its impact on sustainable cities development. It contains eight chapters in which numerous researchers and experts from academia and industries are collaborated.
