The 23 local green tripartite partnerships: participating and chairing municipalities
Updated
Which local tripartite partnership does your municipality belong to, and who leads the work? Here is SGAV's (Danish Agency for Green Transition and Aquatic Environment) overview, brought together in one place. The lists date from January and February 2025, and the appointments could change after the municipal elections, so check the current status with SGAV or KL (Local Government Denmark).

How to read the overview
Each tripartite partnership has a number and a name based on the river basin it covers. Many municipalities belong to several partnerships because municipal boundaries and river basins do not align. The chairing municipality and the municipality providing the secretariat may be the same municipality or two different ones.
