Our projects

C40 City Solutions Platform

By providing cities and solution providers a program for working together on specific climate challenges at an earlier stage than usual, the C40 City Solutions Platform (CSP), a partnership between CLEAN and C40, ensures that the actors reach a common understanding of the challenges in order to co-create solutions. 

Circularity City

In a few decades, most of the world’s population will live in urban areas. This trend creates major challenges in providing sufficient resources to expand and rebuild cities. Conversely, it also provides ideal conditions for developing new ways to design, construct, and furnish our buildings, where all resources are being reused.


CITIES Innovation Center conducts projects with the aim to increase the storage and flexibility capabilities of the energy system so that 100% renewable energy supplies are both possible and attractive.


The aim of the European Cleantech Internationalisation Initiative (EC2i) is to implement a joint internationalization strategy to help SMEs exploit the cleantech opportunities for collaboration in two target countries: The Unites States and China.
