Cities Mission launches Call for Expression of Interest for new Twinning Learning Programme
On 25 June 2025, the EU Cities Mission launched a Call for Expressions of Interest (EOI) for a new Twinning Learning Programme, designed to support the EU Mission: Climate-Neutral and Smart Cities.
This programme offers ambitious cities aiming to advance their climate action a unique opportunity to partner with selected Mission cities and work together towards the goal of climate neutrality. Over the course of one year (November 2025 – November 2026), participating twin cities will engage in structured peer learning and hands-on collaboration. They will also exchange best practices with their paired Mission city.
The programme aims to
- Enable peer-to-peer learning and mutual inspiration by focusing on concrete climate actions and jointly addressing implementation barriers identified by both Mission cities and twin cities
- Support the replication of effective climate actions through co-creating a tailored replication plan for twin cities
- Build long-lasting partnership between Mission and twin cities beyond the duration of the programme
Twin cities will benefit from
- Three progressive learning modules
- Two in-person site visits (to each of the paired cities)
- Targeted support and resources from the NetZeroCities consortium
- Deliverables that help consolidate learnings and shape local climate action planning
The Call for Expressions of Interest is open from 25 June to 12 September 2025 (17:00 CET) to cities not currently part of the 112 Mission Cities, based in EU Member States or Horizon Europe-associated countries.
Interested cities can access the call and submit their application via the online form.
