All Data4GreenDeal’s overall objective is to co-create and shape the European Green Deal Data Space as an open hub for findable, accessible, interoperable and reusable (FAIR) data and standards-based services that support the key priorities of biodiversity, climate change, circular economy, deforestation, and pollution. The focus will be on interoperability concepts that bridge the semantic and technology gaps which currently prevent stakeholders and application domains from multidisciplinary and multi-scale access to data, processing services, and processing platforms.
