The first cohort of 37 Twin Cities from across Europe has been selected in September 2023 to embark upon a journey of shared learning, best practices, and much more.
Discover the Twin Cities
The selected thirty-seven cities, coming from across Europe, have been matched with a Pilot City or cluster of cities already innovating and piloting decarbonisation activities as part of the Cities Mission. See below the list of Twin Cities and the Pilot Cities they have been paired with.

TWINNING LEARNING PROGRAMME
This 20-month program facilitates knowledge sharing and the transfer of best practices between selected Twin Cities and those participating in the 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 a Replication Plan after the learning cycle’s completion.
