The Dutch Government, EU and Dutch National Funding organisations actively support the Golden road to Open Access and encourage publishing in Open Access journals. They suggest that research results (both scientific publications and research data) obtained using public funds must be made freely accessible worldwide. The Green road for publishing research results is also accepted for new NWO and Horizon 2020 projects.
Horizon 2020: The European Union has made Open Access publishing mandatory for research funded by grants through the Horizon 2020 programme. Under Horizon 2020, each beneficiary must ensure Open Access to all peer-reviewed scientific publications relating to its results. One is obliged to deposit peer-reviewed articles and final versions of manuscripts in a repository, or do so within 6 or 12 months after publication. Horizon 2020 projects are also invited to submit data management plans or participate in the Open Research Data Pilot, but this is not compulsory yet.
European Research Council (ERC): You are obliged to make digital copies of your publications available in Open Access within six months of official publication. This can be done through your institute’s repository, in discipline-specific repositories (e.g. AgEcon database for research in agricultural e applied economics) or via your own website.
NWO: NWO requests researchers to publish either in fully Open Access journals (Golden road), or to deposit the article in a centrally managed, findable database of the university or a discipline-specific repository (Green Road). That can also be a non-finalised version of an article, the post peer review pre-published version. It will still be possible to postpone a publication e.g. in case of a patent application.
