Over 800 participants gathered in Helsinki to discuss digital twins, citizen engagement, and the ethical dimensions of smart city technology. Here are the key insights.
The Helsinki Digital Urbanism Forum, held 3–5 February at the Finlandia Hall, brought together an unusually diverse crowd: urban planners sat alongside ethicists, data scientists exchanged ideas with community organisers, and policymakers listened to residents.
The Forum's theme — "Whose Smart City?" — set the tone for three days of frank, nuanced discussion about who benefits from smart city technology and who gets left behind.
Multiple sessions emphasised that digital twins are only as good as the data and perspectives they incorporate. Helsinki's own 3D city model was praised for integrating citizen feedback alongside sensor data.
A recurring theme was the need to embed ethical considerations into smart city projects from day one, not bolt them on later. The Forum endorsed a new "Ethics-by-Design" framework developed by a consortium of Nordic universities.
Some of the most compelling case studies came from smaller municipalities. Tampere, Oulu, and Tartu demonstrated agile approaches to smart city deployment that larger cities often struggle to replicate.
Projects with strong citizen engagement consistently outperform those that rely solely on top-down implementation. The Forum showcased participatory budgeting tools and community data cooperatives as best practices.
Despite progress, data silos and incompatible systems continue to hamper cross-city collaboration. Several speakers called for EU-level standards for urban data interoperability.
"The Helsinki Forum reminded us that the 'smart' in smart cities should stand for socially mindful, accessible, responsive, and transparent." — Sofia Lindqvist
The Smart Cities Hub has curated a collection of resources from the Forum, including session recordings and published papers.
