Why Cities?


Cities are the hub of global power and economy and consume vast amounts of resources. Cities contain the majority of the world's population, and create the vast majority of pollution and emissions that contribute towards global warming.

This consumption of resources is only set to increase with the development of megacities in our lifetime. Massive urban developments of the future could see city populations in Africa and Asia swell to 50 million people or more.

Thanks to innovations in cheap sensor technology, big data, predictive analytics and the arrival of the IoT (Internet of Things), it's becoming easier to tackle all sorts of urban issues.

Here are some of the initiatives taken on by the people running the smartest cities today:


Smart Roads


It is now possible to monitor vehicle and pedestrian levels to optimise or divert traffic depending on conditions. Intelligent, adaptive fast and slow lanes for walking and cycling will also be introduced, and smart traffic lights will start to appear to combat congestion.

Smart Buildings


The introduction of rooftop gardens and vegetation on sides of buildings have helped to lower CO2 emissions whilst also improving insulation. Optimising heating, energy usage, lighting and ventilation are all set to be improved, and wind turbines are more frequently appearing in new building designs.

Smart Lighting


Intelligent and weather adaptive street lights to boost energy efficiency.

Smart Waste Management


Being able to monitor rubbish levels in real-time is becoming increasingly important in order to optimise collection routes and more effectively deal with waste disposal.

Smart Grids


Energy consumption monitoring and management. Uses tech to detect and react to local changes in usage.
