How data are shared and used will determine, to a large extent, the future of democracy and human progress. In this context, the authors of the paper “Sharing is Caring” describe four key requirements that must inform European efforts to ensure that private data are shared and used for the public good in a safe, ethical, and sustainable manner. This paper is part of the “Digitising Europe” initiative and part of a series of discussion papers that are focussed on challenges of European digital policy.
