 ICN’s vision is to be the leading global network of the best performing cleantech cluster organizations from around the world.

ICN’s mission is to create direct value for stakeholders belonging to the clusters, such as companies, knowledge institutions and local authorities, by using international cooperation to enhance their competitive advantages in the global market.


Climate change, rapid urbanization, the depletion of natural resources and a recent global financial crisis have increased the global demand for sustainable solutions and green technologies. Cleantech SMEs (i.e., energy and environment industries) are on the international forefront, using their innovation capabilities and cutting-edge technologies to meet this growing global demand.



By supporting SME development, cluster organizations have successfully promoted SME internationalization, thus increasing exports and generating regional growth in their home regions.
