Overview of Replications Plans submitted by Twin cities (Cohort 1, 2023-2025)

The first cohort of the Twinning Learning Programme (Sept 2023 – May 2025) paired 56 Pilot Cities implementing 25 innovative climate-neutral activities with 37 Twin cities eager to replicate their approaches.

Over nearly two years,cities engaged in a structured programme of online workshops, in-person visits, and facilitated exchanges, enabling Twin cities to closely follow pilot implementation and translate insights into Replication Plans tailored to their own contexts.

The programme demonstrated that well-designed peer learning, anchored in real pilot projects, creates tangible outcomes. Twin cities developed Replication Plans across diverse areas such as sustainable mobility, energy decarbonisation, circular economy, and citizen engagement, while also contributing fresh perspectives that strengthened Pilot city efforts.

The result is Europe’s largest peer-learning initiative under the Cities Mission, with 37 Replication Plans now paving the way toward climate neutrality across a broad range of local contexts.
