The convergence of digital twins and artificial intelligence is redefining how cities operate, moving beyond isolated smart city projects to create a unified, intelligent operating layer. This shift was a central theme at the SmartCitiesWorld Summit 2026, where experts and city leaders discussed how to embed AI into mainstream local government operations for the long term. The summit highlighted that the future of cities depends on connecting people, data, infrastructure, and investment into coherent, place-based strategies.
The Role of Digital Twins in Urban Management
A digital twin is a virtual replica of a physical asset, system, or process that uses real-time data to simulate, predict, and optimize performance. When combined with AI, digital twins become dynamic tools for decision-making. For example, city planners can model traffic flow, energy consumption, or emergency response scenarios without disrupting real operations. This allows for more informed choices, cost savings, and improved resilience.
Dublin is a notable example of a city leveraging digital twin technology. The city has implemented digital twin projects to improve experiences and services for its communities. These projects help reduce traffic congestion, support economic growth, and enhance urban planning. By simulating different scenarios, Dublin can test interventions like new bike lanes or pedestrian zones before making physical changes. The integration of AI further refines these simulations, learning from historical data to predict future patterns.
AI in Public Services: Building Trust and Inclusivity
Artificial intelligence is not just about efficiency; it also promises to make government services more personalized and accessible. However, building trust and ensuring inclusivity are critical challenges. At the summit, a panel discussion titled “AI for personalised government services” addressed how cities can design AI systems that are transparent, fair, and respectful of privacy. This involves engaging communities, avoiding algorithmic bias, and creating clear accountability mechanisms.
Microsoft’s Katherine Flesh emphasized that the greatest opportunities for AI in transport depend on strong data foundations, workforce readiness, and responsible governance. For example, transport agencies are using AI to optimize routes, predict maintenance needs, and improve passenger experience. Without clean data and skilled staff, these systems can fail or exacerbate inequalities. Therefore, cities must invest in data infrastructure and training alongside AI deployment.
Energy Systems and Smart Networks
Energy management is another area where digital twins and AI are making a significant impact. Local authorities can shape energy systems through renewables, flexibility, storage, and smarter networks. Digital twins can model the entire energy grid, from generation to consumption, allowing cities to identify inefficiencies and integrate renewable sources seamlessly. AI algorithms can then balance supply and demand in real time, reducing reliance on fossil fuels and lowering costs.
The SmartCitiesWorld Summit 2026 featured a virtual panel dedicated to how energy systems can be transformed. Panelists discussed the importance of strategic procurement, as argued by Sam Markey, Founder of Recurve. Markey noted that strategic procurement is one of cities’ most underused tools for building resilience, local capacity, and long-term climate impact. By purchasing products and services that align with sustainability goals, cities can drive market change while improving their own infrastructure.
Smart Lighting: A Foundation for Future-Proof Infrastructure
Lighting is often the most visible and widespread municipal asset, and it is rapidly being upgraded to become part of a smarter city operating layer. The “Cities Thriving on Lighting” series within the summit explored how global cities are approaching smart lighting, including the related cybersecurity risks. In one episode, experts discussed the technology and considerations behind turning existing streetlight networks into secure, interoperable, and future-proof infrastructure.
Smart lighting systems can do more than illuminate streets; they can host sensors for air quality, noise, and traffic monitoring, and even provide Wi-Fi connectivity. However, with increased connectivity comes cybersecurity vulnerabilities. Cities must ensure that lighting networks are designed with security in mind, using encryption, regular updates, and segmentation to prevent attacks. The panel stressed that a proactive approach to cybersecurity is essential for maintaining public trust.
Case Study: Sunderland’s Smart City Transformation
Sunderland, a city in the UK, is actively repositioning itself as a leading smart city. It is using digital infrastructure and low-carbon innovation to build a resilient, future-focused economy. The city has been highlighted in a SmartCitiesWorld City Profile, showcasing its commitment to becoming a testbed for new technologies. Sunderland’s strategy includes developing a city-wide digital twin, investing in renewable energy projects, and using AI to improve public services.
One key initiative is the “OnDemand Webinar: Preparing for AI - understanding the data groundwork with Sunderland,” which emphasizes that before deploying AI, cities must have robust data management practices. Sunderland has focused on data standardization, interoperability, and governance to ensure that AI tools can work effectively across different departments. This groundwork is crucial for avoiding silos and maximizing the value of AI investments.
Climate Finance and Resilient Infrastructure
A major theme of the summit was the intersection of climate finance and resilient infrastructure. Cities are increasingly vulnerable to climate change impacts such as flooding, heatwaves, and storms. Digital twins can help model these risks and evaluate the cost-effectiveness of adaptation measures. AI can also optimize the use of funds, directing investments to the most critical areas. The SmartCitiesWorld Summit 2026 demonstrated that a systems-thinking approach is needed, connecting climate goals with economic development and social equity.
Ecomondo, a leading event for green technologies, also participated in the summit, discussing the priorities shaping healthier, more sustainable cities. The organization praised the SmartCitiesWorld platform for sharing practical solutions and building new connections. This collaborative spirit is essential for accelerating the adoption of digital twins and AI in cities worldwide.
Data Foundations and Workforce Readiness
Across all discussions, the importance of data foundations was reiterated. AI systems are only as good as the data they are trained on. Cities must invest in data collection, cleaning, and integration. This includes not only technical infrastructure but also policies for data privacy, security, and ethics. Additionally, workforce readiness is critical. City employees need training to understand and use AI tools effectively, and citizens need digital literacy programs to benefit from new services.
The summit featured a trend report panel discussion on “AI for personalised government services – building trust and inclusivity in cities.” Panelists stressed that inclusivity must be built into AI systems from the start, involving diverse stakeholders in design and deployment. This ensures that services meet the needs of all residents, not just the tech-savvy or well-resourced.
The Intelligent Operating Layer: A Vision for the Future
Combining digital twins and AI creates an intelligent operating layer that can orchestrate city systems in real time. For example, during a heatwave, the operating layer could adjust street lighting to reduce energy consumption, send alerts to vulnerable residents, and activate cooling centers, all while optimizing traffic flow to emergency services. This level of integration requires collaboration across departments and partners, but the potential benefits are immense: reduced emissions, lower costs, improved quality of life, and greater resilience.
Sunderland and Dublin are just two examples of cities leading the way. Many others are embarking on similar journeys, learning from each other through platforms like the SmartCitiesWorld Summit. The newsletters offered by the platform keep stakeholders informed of the latest city interviews, special reports, and guest opinions, fostering a global community of practice.
As the technology matures, the role of strategic procurement, as highlighted by Sam Markey, will become even more important. Cities can use their purchasing power to demand sustainable, interoperable, and secure solutions from vendors. This not only benefits the city but also sends market signals that encourage innovation. Similarly, the cybersecurity considerations raised in the smart lighting panels demonstrate that security must be embedded in digital twin and AI projects from the outset, not added as an afterthought.
The AI revolution in cities is not just about algorithms; it is about building systems that are trustworthy, inclusive, and sustainable. The SmartCitiesWorld Summit 2026 made clear that cities must focus on the fundamentals: data, people, and governance. With digital twins as the canvas and AI as the brush, cities can paint a future that is smarter, greener, and more equitable. The journey is complex, but the tools and knowledge are increasingly available, and the outcomes promise to be transformative.
