The European Commission has launched a public consultation to inform the forthcoming Data Union Strategy. The consultation, announced by President Ursula von der Leyen, seeks views from academia, industry, and researchers on enhancing the use of data in Artificial Intelligence, simplifying data-sharing rules, supporting international data flows, and aligning infrastructures and legal frameworks. It also explores the creation of high-quality, interoperable datasets, bolstering cross-border data flows, and ensuring trust in data usage to support generative AI development. The consultation closes on 18 July 2025.
