Climate Chance Europe 2026 Summit

On June 3rd and 4th, Brussels will host the Climate Chance Europe Summit 2026, focused on “Climate change adaptation, a lever for resilience and prosperity in Europe : preparing and leading the way.” The event will take place at Espace Le Bel and the Maison de la Poste.

At a pivotal moment for European climate policy, as the European Union prepares to revise its climate adaptation strategy, this Summit will bring together key stakeholders in climate action: local authorities, European and national institutions, businesses, NGOs, researchers, and civil society networks.

Situated at the heart of European climate policy debates, Brussels offers a unique setting to foster exchanges between European decision-makers, local actors, and international organizations. The Summit will also highlight local initiatives in adaptation and territorial innovation while strengthening synergies between local, national, and European climate policies.

Following the previous Climate Chance Europe Summits, held in Liège in 2024 and Marseille in 2025, this new edition aims to further mobilize territories and non-state actors to accelerate the adaptation of European societies to the impacts of climate change.

Over the course of two days, the Summit will provide a space for dialogue, cooperation, and advocacy around concrete adaptation solutions, aiming to strengthen territorial resilience and inform the direction of European policies.

Objectives of the Summit

1. Contribute to the review of the European adaptation strategy

The Climate Chance Europe Summit 2026 takes place at a strategic moment for the European Union, marked by the revision of the EU’s climate change adaptation strategy.

It will serve as a platform for dialogue among European institutions, Member States, territories, and non-state actors to contribute to the direction of this forthcoming strategy. Building on the declarations from the Liège (2024) and Marseille (2025) Summits, the Summit’s discussions will feed into the European debate with proposals and lessons learned from local territories.

Special attention will be given to adaptation financing, nature-based solutions, new tools for climate risk management, and the role of economic and insurance actors in building a resilient Europe.

2. Strengthening multi-level governance of adaptation in Europe

In the face of accelerating climate impacts, adaptation requires strengthened coordination across all levels of governance. The Summit will facilitate exchanges between local authorities, European institutions, national governments, and civil society to enhance the coherence of public policies and their territorial implementation.

Discussions will highlight initiatives led by European territories, as well as innovations developed in Brussels and Belgium. Exchanges will also showcase cooperation between urban and rural territories, territorial adaptation solutions, and multi-stakeholder consultation mechanisms.

3. Giving a voice to non-state actors on the European and international agenda

The Summit will result in the development of a collective advocacy initiative led by the major non-state actor networks mobilized through Climate Chance.

This Brussels Declaration will present key messages and practical recommendations to strengthen adaptation policies and the resilience of European territories. It will be offered for endorsement to major European and international networks of local authorities, businesses, NGOs, and civil society organizations.

The advocacy will then be promoted at major international climate events to reinforce Europe’s contribution to global adaptation efforts.
