Global cities now account for more than half of the world’s population, and the United Nations projects the number to balloon to 68 per cent by mid-century. How will urban residents navigate cities, and how will cities meet essential needs like energy, water, and sanitation? From Singapore to Dubai and London, here are the top smart cities to look for in 2025.

Major projects like Saudi Arabia’s Neom stand as an example of what smart cities offer - improve living standards, manage resources efficiently, and support sustainability. Smart cities, powered by the latest technologies like digital twins, Artificial Intelligence (and now increasingly AGI), Internet of Things (IoT), amongst others, allow real-time monitoring and quick responses to urban needs.

A smart city uses modern technology to improve the quality of life for its residents, support urban living, and address issues such as pollution, waste management, and safety. The goal of a smart city is to create a sustainable and well-connected environment where local people can thrive. What are the top 10 smart cities reshaping the world in 2025?

Smart cities are using advanced digital technologies and rely on a network of sensors, data analysis, and artificial intelligence to create connected systems that improve various aspects of urban life, such as traffic management, energy use, healthcare, and waste disposal.

By 2024, the smart cities market in North America alone is expected to reach US$14.52 billion, with similar growth trends seen worldwide. 

The goal of developing smart cities is to tackle issues linked to urbanisation, resource shortages, and environmental harm. Through technology-based solutions, these cities aim to become more sustainable and efficient as populations grow and resources become more limited. The ultimate aim is to ensure these advancements are fair and beneficial for all citizens, creating urban spaces that support both present and future generations.

Features of a Smart City

A smart city uses technology and new ideas to improve how people live while ensuring resources are used carefully and sustainably. Below are some key features of a smart city, explained simply:

  1. Smart Transport
    Smart cities make it easier for people to move around by improving public transport, using self-driving vehicles, and managing traffic with technology. Singapore has a system that adjusts traffic lights and bus routes based on real-time data to reduce congestion. 
  2. Sustainable Energy
    Smart cities rely on renewable energy sources like wind and solar power. They also use smart grids to distribute energy efficiently. Copenhagen aims to become carbon-neutral by 2025, using wind power and a district heating system to achieve this.
  3. Water and Waste Management
    Managing water and waste is essential in any city. Smart cities use technology to monitor water usage and prevent wastage. Barcelona has a system that checks for leaks and ensures rubbish is collected only when bins are full, saving time and fuel.
  4. Digital Governance
    Smart cities make government services easier to access online. Tallinn, Estonia, allows residents to vote and file taxes through digital platforms. 
  5. Strong Infrastructure
    Smart cities build structures that can withstand challenges like extreme weather or natural disasters. Tokyo has earthquake-resistant buildings and automated systems to respond to emergencies.
  6. Public Safety
    Smart cities use cameras and artificial intelligence to improve safety. London’s CCTV system helps police monitor and reduce crime.
