Horizon 2020 policy on Open Access publishing*

Horizon 2020: Open Access required for peer-reviewed journal articles
The European Commission requires the open access publication of academic peer-reviewed journal articles. This must be done in two steps:

  • Step 1: Deposit the article in a repository
  • Step 2: Guarantee Open Access through the repository within the accepted period of embargo (6 or 12 months, depending on field of research)

Support for the Horizon 2020 Open Access policy
If you are currently working for a project of Horizon 2020, you can deposit your publications in the TU/e Repository. This fulfills the first step.

The Information Expertise Center is pleased to provide support for the second step – preparing a publication for Open Access within the period of embargo specified by Horizon 2020. The IEC will then automatically make the article available through Open Access as soon as it is allowed by the publisher. Horizon 2020 specifies that an article must be available through open access within six months after publication. An exception is made for the fields of humanities and social sciences, for which a twelve-month embargo period is allowed.

Determine whether your journal meets all of the conditions of Horizon 2020:

If a publisher does not allow your article to be made available through Open Access in the TU/e Repository within six or twelve months, you have three alternatives:

  1. If the journal of your choice also offers the option of publishing your article through gold Open Access for a fee, you may choose to do so.
  2. Publish in another traditional journal. In doing so, choose a journal that will allow Open Access in the TU/e Repository within the specified period (see embargo list).
  3. Publish in a gold Open Access journal (additional information on gold Open Access publishing).


The European Commission offers the option of paying the costs of Open Access from your project budget. There are no additional funds to which the costs of Open Access can be declared after the end of a project. You must therefore include the Open Access costs in advance in your project budget.
