New World Cities - Prof. Greg Clark CBE
Greg Clark’s work spans more than 400 cities across six continents as an advisor, researcher, writer, host, and convenor. He is driven by a single conviction: that cities and the built environment, when well led and well understood, are among humanity’s most powerful instruments for creating shared prosperity, sustainability, common space, beauty, and belonging.
Conference hosting is a central part of his work. He chairs, moderates, and hosts events across the urban, real estate, investment, destination, and governance sectors, returning to many of the same organisations year after year. He is also an active podcaster with a global audience, presenting two international series, The Century of Cities and The DNA of Cities, which keep him in continuous dialogue with city leaders, investors, and built environment professionals worldwide.
His approach to hosting combines deep preparation and subject knowledge with intelligent questioning, concise synthesis, audience engagement, dynamic use of polling and participation, and precise timekeeping. He researches the positions of speakers in advance, asks questions that move discussions forward, and connects ideas across sessions to give audiences a clear and useful perspective. His ability to engage delegates as active participants helps create meaningful exchange, even in large plenary settings.
What distinguishes Greg is the depth of knowledge he brings to the stage. His research and three frameworks — The DNA of Cities, The Century of Cities, and The Planet of Cities — enable him to understand the issues and debates shaping cities and the built environment. He has worked directly with mayors, investors, developers, and executives around the world, often having advised or collaborated with the people he introduces and interviews.
Greg is one of the most experienced chairs in the international real estate investment community, with long-standing relationships across INREV, ANREV, EPRA, EXPO Real, ULI Europe, and the London Real Estate Forum. He hosts city leadership events including the World Cities Summit Mayors Forum, Scottish Cities Week, and Glasgow State of the City Economy; destination and business events with Destinations International, IMEX, and the City Destinations Alliance; and built environment gatherings including the NLA Built World Summit.
As former Chair of Connected Places Catapult, the United Kingdom’s national innovation accelerator for cities, transport, and place leadership, Greg also brings particular expertise in innovation and technology and their role in shaping the future of cities and places.
