In this episode, recorded at the Smart City Expo World Congress 2025, we travel to the City of Hamburg with Dr. Nora Reinecke, Project Manager for the Connected Urban Twins project.

Nora explains how Hamburg is moving beyond the buzzwords to implement digital twins that address real urban challenges, from climate resilience and flooding to complex urban planning scenarios. She discusses the collaborative approach among Hamburg, Leipzig, and Munich, emphasizing the need for open-source tools and demand-driven strategies rather than technology for its own sake.

The conversation also covers the practical application of GeoAI, the importance of citizen participation, and how to mitigate bias in urban data to ensure inclusive outcomes for all residents.

In this episode, recorded live at the Smart City Expo World Congress 2025 in Barcelona, we travel to France to explore a pragmatic vision for sustainable urban development. We are joined by Gérard Wolf, Special Advisor for Smart & Sustainable Cities to the Minister for Europe and Foreign Affairs, who shares the French approach to building resilient cities based on four essential services: energy, water, waste management, and transportation.

Gérard discusses why simplicity must be prioritised over complex technological fixes and how this mindset drove the massive decarbonisation efforts behind the Paris 2024 Olympic Games. We also delve into the importance of the circular economy, specifically the strategic shift from demolition to retrofitting existing buildings. Finally, the conversation highlights a crucial human-centric challenge: ensuring that Smart City progress does not leave behind those living in informal settlements, making inclusivity a global priority.

In this episode, we travel to Italy with Francesco Leonardo Nelli, Coordinator of the International Relations Unit at the City of Bologna. Recorded live at the Smart City Expo World Congress 2025 in Barcelona, we discuss how the city leverages its strong cooperative spirit to drive modern innovation.

The conversation highlights Bologna's distinct approach to technology. Rather than purchasing standard solutions, the city is developing a homegrown Digital Twin from scratch to ensure it fits local needs, with initial use cases focused on mobility. Francesco also discusses the role of the Foundation for Urban Innovation in bridging the gap between the administration and residents, illustrated by the "School Squares" project that reclaims space for children.

Join us to learn how Bologna balances its rich history with future-ready strategies through city diplomacy and active civic listening.

In this episode, recorded live at Smart City Expo World Congress 2025 in Barcelona, we are joined by Eddie Copeland, Director, and Genta Hajri, Digital Innovation Delivery Lead at the London Office of Technology and Innovation (LOTI).

London consists of 33 separate administrative areas, which can often lead to fragmented public services. Eddie and Genta explain how LOTI acts as a collaborative layer, helping boroughs use data, technology, and innovation to solve shared challenges together.

The conversation covers impactful initiatives such as 'Get Online London', the city's digital inclusion service, and how improved data sharing is ensuring vulnerable children are auto-enrolled for free school meals. We also explore the practical application of AI in social care to support workflows while maintaining human accountability, and the team's unique use of immersive theatre to build empathy and better partnerships between the public and private sectors.

In this episode, recorded live at Smart City Expo World Congress 2025 in Barcelona, we sit down with Darío Moreno, Mayor of the Municipality of Sagunto, Spain. He shares the story of how his city secured a historic €3 billion investment for a Volkswagen battery gigafactory, positioning Sagunto as a key player in Europe's reindustrialisation.

Our guest explains the "leap of faith" required to develop 5 million square meters of industrial land in record time and how this project is transforming the local economy. He also discusses the unique challenge of governing a city with two distinct souls, the 3,000 year old historic centre and the industrial port, while managing housing pressures and mobility.

We also dive into his background as a United Nations lawyer, his call for stronger multilateralism, and why he compares Sagunto's bright future to a blooming orchid.

Dans cet épisode, Guillaume Ruet, maire de Chevigny-Saint-Sauveur et conseiller départemental de la Côte-d’Or, partage sa vision d’une ville à taille humaine qui refuse d’être une simple cité-dortoir en périphérie de Dijon. La conversation aborde ses quatre grandes priorités : sécurité et tranquillité du quotidien, transition écologique ambitieuse (écoles rénovées, patrimoine décarboné, milliers d’arbres plantés), soutien aux familles et aux aînés avec la démarche « ville amie des aînés », et lutte contre le décrochage civique l’incivisme par une « démocratie implicative » où chacun contribue. Il revient aussi sur l’aide aux commerces locaux en temps de crise, le rôle du sport comme politique de santé et de cohésion, et sa définition très humaine de la Smart City : anticiper les besoins de demain, impliquer les habitants et refuser le « ce n’est pas possible ».

In this episode, Isaac Silveira, Municipal Director of the Department of Communication, Technology and Image at the Municipality of Cascais, Portugal, paints for us the portrait of Cascais as a “human” Smart City, where technology is a tool to strengthen relationships, build trust and improve daily life for residents, workers, students and visitors.

Our guest explains how the Cascais Operations Centre and Cascais BI enable real-time, data-driven decisions, while the open GeoCascais platform empowers citizens with transparent spatial information. He also discusses tourism management, sustainability on the Atlantic coast, breaking silos inside the municipality, and his vision of being “smart with a soul” – combining digital intelligence, social inclusion and environmental resilience for future generations.

In this episode recorded live at the RethinkCities Summit 2025, Allan Pilgaard-Jensen, Managing Director of ProjectZero for the City of Sønderborg, Denmark, and Drew Turner, Director of Global Decarbonisation Solutions at Danfoss, share how Sønderborg is working towards carbon neutrality by 2029 through a long-standing public-private partnership.

The conversation explores why successful energy transitions are “80% people and 20% technology,” highlighting the importance of governance “hotspots,” stakeholder ownership and clear business cases for every project. They discuss Sønderborg’s “lighthouse” initiatives that link hospitals, data centres and industries through district energy and heat recovery systems, showing how concept designs and shared master plans avoid silos and build momentum.

Allan and Drew also reflect on replicating this model in larger cities, the economics of the final 10% of decarbonisation, including carbon capture, and why collaboration and realistic payback are crucial to scaling climate action. Throughout, they stress that Smart Cities thrive when plans turn into projects with shared benefits for people and business alike.
