As part of its work within the NetZeroCities project, ERRIN has developed three case studies showcasing the critical role that regions can play in the EU Mission on 100 Climate-Neutral and Smart Cities by 2030, using examples from ERRIN member regions. With their climate-related competencies and responsibilities within national governance structures, and role in implementing national policies and facilitating financing, regions are uniquely positioned to support cities in achieving their climate neutrality goals.

The case studies highlight best practices from the following regions and countries: Blekinge Region (SE), Valencia Region (ES) and Poland (Lower Silesia, Małopolska, Mazovia, Łódzkie and Podkarpackie).
