The International Cleantech Network (ICN) is a global alliance of 22 leading cleantech clusters across four continents. Together with members and partners like C40 Cities, ICLEI, and the Solar Impulse Foundation, we help cities, regions, and global companies tackle their most pressing environmental challenges. 

With fast access to over 7,000+ cleantech SMEs, 250+ knowledge institutions, and 130+ public authorities, ICN accelerates the path from challenge to solution. As an official observer to COP30, we stay at the forefront of global climate policy — and we understand how to navigate international funding mechanisms to turn ambition into action.

Specialized in thematic groups covering energy, circular economy, and watertech solutions — and continually expanding into emerging areas of cleantech innovation.
