External Expert Advisory Board
The External Expert Advisory Board (EEAB) brings together independent experts from across Europe with expertise in urban greening, nature-based solutions, climate resilience, governance, biodiversity and related fields. The Board provides strategic guidance and external perspectives to support the project's quality, relevance and long-term impact. Through their experience and networks, EEAB members contribute valuable insights that help strengthen C2G's approach to building greener, healthier and more resilient cities.
