Groningen is a member of the Dutch Climate Adaptation Network in medium-sized Cities (KANS). Through this network, Groningen collaborates with other Dutch cities on climate change problems specific to medium-sized cities. The subjects these cities focus on are: (1) climate change on district level, (2) climate adaptation and the new environmental act and (3) city and surroundings. The Ministry of Infrastructure & the Environment, CAS, Tilburg and Planbureau voor de Leefomgeving (Planning Agency for the Physical Environment) are also involved and part of the KANS network inspiration group.
