Open Access for EU projects

With the programmes Horizon 2020 (2014-2020) and Horizon Europe (2021-2027), the European Union is one of the biggest research funders in the world. To ensure free access to project results the EU mandates Open Access for peer-reviewed scholarly publications. You can find short policy summaries here.
