This research report presents the findings of an ongoing multi-centre comparative analysis of ‘smart-eco city’ initiatives in the UK. The ‘smart-eco city’ concept captures the recent trend for future-oriented urban development schemes that display both ‘green’ and ‘smart’ ambitions. More precisely, the smart eco-city is defined here as an experimental city, functioning as a potential niche for testing and introducing environmental and economic reforms. The report forms part of an ESRC-funded research project titled SMART ECO-CITIES FOR A GREEN ECONOMY: A COMPARATIVE STUDY OF EUROPE AND CHINA, coordinated by the University of Exeter in collaboration with an interdisciplinary team of researchers from King’s College London, the Universities of Westminster, Plymouth and Cardiff. The international partnership includes research teams in China, France, Germany and the Netherlands.
