The third cohort of 24 Twin Cities from across Europe has been selected in January 2025 to join the Twin Cities portfolio and embark upon a learning journey towards climate neutrality.
Discover the Twin Cities
The selected twenty four cities, coming from across Europe, have been matched with a Pilot City or cluster of cities from Cohort 2 and Cohort 3 already innovating and piloting decarbonisation activities as part of the Cities Mission.

NETZEROCITIES TWINNING LEARNING PROGRAMME
This 17-month programme facilitates knowledge sharing and the transfer of best practices between selected Twin Cities and those participating in the NetZeroCities’ Pilot Cities Programme.
Through practical knowledge exchange and peer learning, Pilot Cities share their experiences with Twin Cities, who, in turn, integrate these lessons into their own urban planning through an Action Plan after the learning cycle’s completion.
