Citizen Observatories (CO) are initiatives that empower citizens to actively participate in the collection, analysis, and interpretation of data to address various issues affecting their communities and contribute to policy-making and community development.

Five Citizen Observatories (CO) based at four different European cities and regions (pilots) are used to create collectively the GREENGAGE Citizen Observatory Academy (CO Academy). The CO Academy serves as a knowledge base to store and index training materials, success stories, findings and best practices collected from the five CO pilots: Bristol (UK), Copenhagen (DK), Gerace (IT), Turano (IT), and North Brabant (NL).

GREEN Engine is a platform developed to enable GREENGAGE CO activities. It is based on the model of ESA’s Urban-TEP (Urban Thematic Exploitation Platform) and consists of a wide assortment of digital services, tools and infrastructures to support the data-mining cycle (gather – validate – control – analyse – manage – interpret – visualise – publish – exchange). The platform will configure data value chains that combine official data (such as EU Copernicus and municipal data) with crowdsourced data (provided by citizens through wearables or proprietary devices and apps) to generate evidence that inform improved models of urban governance.

GREENGAGE Knowledge Base is a centralized repository of freely available information, training materials, procedures and data that serves as a valuable resource for individuals interested in taking part in Citizen Observatories and used for enhancing productivity and fostering collaborative and continuous learning.
