Sustainable Digital Cities

A European Project



Alhambra, the first sustainable city

Dominating the Spanish city of Granada, the Alhambra is a remarkable testimony to Andalusian architecture. Added to the ancient urban structures, innovative water-management techniques and gardens incorporated into this urban environment make the Alhambra the first model of a sustainable city.



HAMBURG, a smart port

Thanks to its hyper-connected port, the free city of Hamburg is open to the world. Equipped with sensors and heavily automated, the port's new infrastructures make extensive use of renewable energy. The HafenCity – one of Europe's most ambitious urban projects – is now emerging on the brownfield site of the old port.



SMART CITY made in France

With their economy, environment, forms of mobility, energy, and habitat governance, French cities have major assets to achieve what smart cities promise. But can we talk about a 'French model' for smart cities?



VIENNA, a model Smart City

The former imperial capital has accelerated its move into the modern world by drawing up a smart-city strategy based on three pillars: quality of life, resource management, and innovation. The Aspern quarter is emerging as a testing ground for a sustainable digital city.



1,000 solutions for a more sustainable world

How can we achieve cleaner mobility, energy-neutral buildings, and industrial processes that emit less CO2? By developing lucrative technology that creates the jobs, profit, and sustainable growth needed throughout the world. The Nesting Company is a partner of the World Alliance for Efficient Solutions.



ESSEN, a city's ecological transformation

The former mining town – symbol of the Ruhr region's industrial tradition – has reinvented a coal-free, pollution-free future for itself. As the green capital of Europe, Essen's energy transition is built on public-private partnerships and a major renovation plan.
