All Data for Green Deal (AD4GD) is a European project led by CREAF that will help to unify all Earth observation data in a single space and thus support priority actions of the European Green Deal. Just as a storage room can become an efficient warehouse if everything is sorted, labelled and accessible to everyone, this project aims to ensure that the future Common European Data Space will be an open, traceable and understandable information warehouse. Consequently, decision-makers will be able to consult them easily and undertake more effective policies on biodiversity, pollution and climate change.
