NetZeroCities visual announcing peer learning opportunities

Join the Cities Mission Online Discussion Groups

The Mission Platform, managed by NetZeroCities and where ERRIN contributes to citizen and stakeholder engagement, invites expressions of interest from cities across Europe to join the Cities Mission Online Discussion Groups.  

This six-month programme is designed to accelerate local climate action through structured peer learning and expert guidance, offering offer cities the opportunity to learn directly from pioneering Mission Cities that are already implementing ambitious climate-neutral solutions. 

This edition, running from September 2025 to February 2026, will support participating cities with tailored one-to-one expert support, opportunities for study visits to Mission Cities, access to exclusive tools and the Mission Portal and a dynamic peer-to-peer exchange environment. 

Thematic focus areas 

Participating cities will explore solutions across four key areas, guided by cities with hands-on experience: 

  • Innovative financing: Florence & Malmö
  • Decarbonising energy and district heating: Pécs, Lund & Espoo
  • Built environment and circular construction: Helsinki & Oslo
  • Citizen engagement and behavioural change: Helsingborg & Grenoble-Alpes Métropole 

The first edition of this programme brought together 180 participants, underscoring the high level of engagement and the value of peer exchange in driving forward local climate actions. This is an excellent opportunity for cities to co-develop practical approaches to climate neutrality, while leveraging the lessons learned and tested by leading Mission Cities.
