The present study aims to examine, monitor and quantify compliance with the open access requirements of the MGA, for both publications and research data. The study concludes with specific recommendations to improve the monitoring of compliance with the policy
under Horizon Europe, together with an assessment of the efficiency and effectiveness of the Horizon 2020 open access policy.
The key findings of this study indicate that the European Commission’s leadership in the Open Science policy has paid off. Compliance has steadily increased over recent years, achieving a success rate that places the European Commission at the forefront globally (83% open access to scientific publications). What is also apparent from the study is that monitoring – particularly with regard to the specific terms of the policy – cannot be achieved by self-reporting alone, or without the European Commission collaborating closely with other funding agencies across Europe and beyond, to agree on common standards and the common elements of the underlying infrastructure. In particular, the European Open Science Cloud (EOSC) should encompass all such components that are needed to foster a linked ecosystem, in which information is exchanged on demand and which eases the process for both researchers (who only need to deposit once) and funders (who need only record information once).
