ClimaGen

ClimaGen focuses on urban greening and renaturing to promote climate-resilient regeneration in European cities, particularly in vulnerable neighbourhoods. ClimaGen contributes jointly to the EU Mission 100 Climate Neutral and Smart Cities by 2030 and the EU Mission Adaptation to Climate Change, and uses methods of the New European Bauhaus.
Time Period

1st January 2025 - 31st December 2028

Location

Belgrade, Gdańsk, Tartu, Torino, Trondheim, Cluj-Napoca, Eindhoven, Gernika, and Thessaloniki

Funded by

European Union  (HORIZON-IA - HORIZON Innovation Action)

Introduction

About the project

Old buildings in vulnerable neighbourhoods pose challenges to achieving net-zero emissions. Climate-resilient regeneration and ecological restoration offer solutions. The EU-funded ClimaGen project will demonstrate how such measures can help achieve net-zero emissions by increasing public green spaces by 25 % in five cities: Belgrade, Gdańsk, Tartu, Torino, and Trondheim. Additionally, the project will implement shorter-term, co-creative measures in four replication cities: Cluj-Napoca, Eindhoven, Gernika, and Thessaloniki. Each of the nine cities will oversee specific work packages, supported by five cross-cutting concepts and four transversal work packages. ClimaGen aims to enhance resilience, prevent maladaptation, and foster collaboration within local governance, incorporating arts, culture, and youth engagement to drive sustainable urban transformation.

Our Role

GIB’s approach and contributions

GIB contributions

Global Infrastructure Basel Foundation (GIB) leads ClimaGen Finance, helping the nine cities turn nature-based solutions into investable projects. GIB supports cities to navigate EU public investment facilities and to access loans, grants and blended finance, co-creating tailored investment and partnership models for each context. GIB brings expertise in sustainable finance and resilient infrastructure. It convenes city-specific arrangements— including de-risking options such as insurance— and develops financing concepts that optimise the value of ecosystem services from urban NbS. GIB contributes insights through City Dialogues and Sense-Making Sessions and channels them into the project’s Impact Model and Guidance Package, enabling replication and scale across Europe. By the end of ClimaGen, concrete urban climate finance initiatives will be co-developed with cities.
