Open Science in Horizon Europe

As part of the new Horizon Europe programme, the Commission has developed a comprehensive Open Science policy. Open Science is now considered to be an integral part of the research process, from the initial proposal-writing stage all the way to post-award reporting.

The Open Science approach is based upon open, cooperative work and systematic sharing of knowledge and tools as early and widely as possible. This is seen as crucial for increasing the quality and efficiency of research projects. It also speeds up the advancement of knowledge and subsequently benefits the entire innovation process.

Open Science practices include:

  • Early and open sharing of research
  • Research output management and measures to enable the reproduction of research outputs
  • Providing open access to research outputs (see accompanying guides below on publications and research data)
  • Participation in open peer-review throughout the research process
  •  Involving a range of people in the co-creation of research and innovation agendas (e.g. citizens, civil society representatives and end users)

In Horizon Europe there are both mandatory practices, which are required for all projects, and ‘recommended’ practices (anything from the list above that doesn’t appear under mandatory practices). By including both mandatory and recommended Open Science practices in your proposal you will increase its evaluation score.

Mandatory Open Science Practices

  • Open access to scientific publications under the conditions required by the grant agreement
  • Responsible management of research data in line with the FAIR principles (see accompanying guide on open science re. research data)
  • Information is shared about the research outputs/tools/instruments needed to validate the conclusions of scientific publications or to validate/re-use research data
  • Digital or physical access to the results needed to validate the conclusions of scientific publications (unless exceptions apply)
  • In cases of public emergency, if requested by the granting authority, immediate open access to all research outputs under open licenses. If exceptions apply, access under fair and reasonable conditions to legal entities that need the research outputs to address the emergency

Including Open Science practices in your Horizon Europe proposal

  • Refer to the Horizon Europe Programme Guide for detailed guidance on how to address open science practices in your proposal.
  • Open science practices are considered in the evaluation of proposals, in both the ‘Excellence’ and ‘Quality and efficiency of implementation’ sections.
  • You must provide concrete information on how you plan to comply with the mandatory open science practices. Failure to sufficiently address this will result in a lower evaluation score.
  • Additionally, a clear explanation of how you will adopt recommended practices, as appropriate for your project, will result in a higher evaluation score.
  • If you believe that none of the open science practices (mandatory or recommended) apply to your project, you must provide a justification.
  • See the accompanying guides below on Publications and Research Data for specific guidance on each aspect
