“The Ecocity Summit is a tremendous gathering of city-focused people from all regions of the world and from all backgrounds: academics, youth activists, policy makers, urban planners, ecologists, and concerned citizens. Such diversity helps compost old ideas into fertile new directions of thinking, taking action, and working together. That’s what the theme of connecting communities is all about. It’s what’s desperately needed to transform our battered social and ecological systems.”

Prof Catalina Turcu

Professor of Sustainable Built Environment, Bartlett, UCL

Catalina Turcu is Professor of Sustainable Built Environment at the Bartlett School of Planning, University College London (UCL). Her work contributes to the understanding and measurement of urban sustainability at the local level. Theoretically, her research adds the institutional dimension to the traditional three-pillar (economic, social, environmental) understanding of sustainability.   

Empirically, Catalina examines sustainable urban transformations at the local level by integrating social, institutional, and physical aspects of the built environment. More specifically, Catalina’s core expertise spans across three areas: the role of institutions in shaping urban sustainability; the social context of urban sustainability; and material narratives of urban sustainability.   

She has published widely, contributed advisory roles to many national and international organisations, and fulfilled scientific appointments with the World Bank (WB), United Nations (UN), Organisation for Economic Cooperation and Development (OECD) and World Health Organisation (WHO). Catalina is a trained architect and worked in architecture and planning consultancy for 10 years before joining Academia.  

“Any sustainable city model remains largely a social and political challenge not a technical fix.”
