The Urban Summit Brussels 2025 kicked off with a powerful opening keynote titled “The Future of European Cities: Resilience, Innovation, and Inclusion.” Delivered by Dr. Elena Martens, Director of the European Urban Policy Lab, the address set the tone for three days of debate and collaboration. Against the backdrop of the Brussels-Capital Region — home to 1.2 million residents and the EU institutions — Dr. Martens outlined a roadmap for cities navigating climate change, digital transformation, and social inequality. This article recaps the keynote’s main themes and the lively Q&A that followed.

Keynote Highlights: A New Urban Agenda for Europe

Dr. Martens began by referencing the Leipzig Charter and the New Leipzig Charter, which have guided European urban policy since 2007. She argued that the next decade demands a more integrated approach — one that merges the Green Deal targets with digital innovation and social cohesion. “Cities are where the future happens first,” she said. “We have to make them livable for everyone, not just the privileged few.”

She presented three pillars for the future:

  • Climate-Neutral Districts: By 2030, 100 European cities aim to become climate-neutral, as part of the EU’s 100 Climate-Neutral and Smart Cities Mission. Dr. Martens highlighted Brussels’ own ‘Neighborhood Contracts’ — participatory renewal programs in districts like Matonge and Anneessens — as models for combining energy retrofits with community engagement.
  • Digital Twins and Data Commons: She called for every European city to develop a digital twin — a virtual replica that simulates traffic, energy use, and climate impacts. Helsinki and Barcelona already have operational twins. Brussels launched its own in 2024 under the Smart Region initiative, costing €2.5 million. Dr. Martens stressed that data must be a public good, not a private commodity.
  • Affordable Housing and the “15-Minute City”: The keynote praised Paris Mayor Anne Hidalgo’s ‘15-minute city’ concept, where all daily needs are within a short walk or bike ride. Dr. Martens noted that Vienna and Milan are also adopting this model. For Brussels, she pointed to the ‘Plan Logement 2025-2030’, which aims to create 15,000 social housing units with an investment of €1.8 billion from the Brussels-Capital Region.

Panel Discussion: From Vision to Practice

Following the keynote, a panel of four experts joined Dr. Martens on stage:

  • Ahmed Benali, Chief Digital Officer of the City of Amsterdam
  • Laura Costa, Director of the European Climate Foundation’s Urban Programme
  • Mateusz Kowalski, Mayor of Gdańsk (via video link)
  • Sophie Van der Meulen, Professor of Urban Studies at the Vrije Universiteit Brussel

The discussion focused on implementation challenges. Mr. Benali warned that digital twins risk exacerbating inequality if citizens lack digital literacy: “We have to invest in digital education alongside infrastructure.” Ms. Costa highlighted the need for EU funding — notably the European Regional Development Fund (ERDF) and the InvestEU programme — to support smaller cities. Mayor Kowalski shared Gdańsk’s experience with participatory budgeting, where residents directly decide on 5% of the city’s investment budget (approximately €12 million annually). Professor Van der Meulen cautioned against a one-size-fits-all approach: “European cities are diverse. What works in Copenhagen may not work in Bucharest.”

Key Data Points from the Keynote

Dr. Martens supported her arguments with concrete figures:

  • 74% of Europeans live in urban areas, a figure expected to reach 80% by 2050 (European Commission, 2024).
  • Urban areas account for 70% of global CO₂ emissions, but also offer the greatest potential for efficiency gains.
  • The EU’s Urban Agenda for the EU has funded over 1,200 projects since 2016, totaling €4.5 billion.
  • Brussels’ Good Food Strategy has reduced food waste by 30% since 2020 and aims to make 30% of food organic by 2035.

Reactions from the Audience

The keynote drew a packed room of over 400 delegates — policymakers, urban planners, architects, and civil society leaders. During the Q&A, questions ranged from gentrification risks in the 15-minute city to the role of autonomous vehicles. One delegate from Warsaw asked how to finance digital twins for cities with tight budgets. Dr. Martens suggested public-private partnerships and cited the example of Barcelona’s ‘CityOS’, funded partly by the European Innovation Council. Another question addressed participatory democracy: a representative from CitizenLab (a Brussels-based civic tech startup) noted that their platform has been used by over 200 European cities to crowdsource policy ideas.

Looking Ahead: The Summit Programme

The opening keynote set the stage for a packed schedule. Over the next two days, attendees can choose from 12 breakout sessions, 8 workshops, and 2 site visits — including a tour of the Tour & Taxis redevelopment and the Canal Zone smart district. Key sessions include “Financing the Green Transition,” “Mobility as a Service (MaaS) in Practice,” and “Inclusive Digitalization.” The summit also features a Startup Village with 30 exhibitors showcasing urban tech solutions, from smart waste bins (by Ecube Labs) to air quality sensors (by Airly).

Dr. Martens concluded her keynote with a call to action: “We have the knowledge, the tools, and the resources. What we need now is the political will and the collective courage to transform our cities. Let’s make the future happen — together.”

The full summit programme and speaker list are available on the Urban Summit Brussels website. For those unable to attend in person, many sessions are livestreamed and recordings will be posted within two weeks.
