Citizen
Observers
Welcome to the International Community of Citizen Observers (CoCO), the European platform where your environmental observations are turned into policy action and real-world change.
Uniting for a Greener Future
The Challenge
Across Europe, thousands of citizens monitor their environment, but their efforts are often isolated. This fragmentation dilutes the power of data and slows the potential for systemic change.
Our Solution
The CoCO was born to break these silos. We are a collaborative ecosystem connecting observers, researchers, and policymakers. Here, your data isn't just collected; it's validated, contextualized, and used to build a bridge of credibility that informs and transforms urban governance.
