Building cities that deliver the future

As our digital and real worlds become increasingly interwoven, Siemens is helping to shape tomorrow’s smart cities.

Digitalization is the essential key that unlocks solutions and opportunities

The Atlas of Digitalization examines the digital readiness and potential of cities around the world. This serves as a useful indicator of how technology is being embraced, and how much value can still be realized.

Compare the progress of digitalization in cities

Every city has a unique capacity to adapt and grow with the trends that drive transformation. The Atlas of Digitalization presents a fascinating comparison of how cities in diverse parts of the world are using technology to achieve their objectives, from reducing greenhouse gas emissions to building an integrated city infrastructure.



Digitalization readiness scores a city’s current digital infrastructure and its preparation for a connected future.


Digitalization potential scores a city’s opportunities for improvement using digital technology.

Data sources

Our research is based on 21 indicators covering the three themes of Expo 2020 Dubai. Each featured city is assessed for its sustainability, mobility, and opportunity.

We took the most recent indicator data from a broad range of sources to calculate a score out of 10 for each city.
