Along with the benefits of open access, increasing numbers of research funders operate a mandate that funded research be disseminated via open access. For example:
Plan S 10 principles: scientific publications publicly funded by national and European research councils must be published open access.
Sherpa Juliet: Research Funders' Open Access Policies.
Deposit your research in a repository in compliance with publisher author-archiving policies (for example, the Author's Accepted Manuscript version of your journal article).
Research output versions: including the Author's Accepted Manuscript.

Publish your research in an open access (OA) journal:
Gold: peer reviewed articles published in online open access journals that are free to the public. The author or the author's institution is usually required to pay an article processing charge (APC) fee.
Hybrid: subscription-based journals which allow a portion of articles to be open access - usually on payment of an APC.
Platinum: also called diamond OA. journals that are free for authors to publish in and freely accessible online. Platinum OA journals are usually funded by non-profit organisations (e.g. universities) or by donations.
Green: published version or manuscript accepted for publication, available at repository.
Bronze: published version or manuscript accepted for publication, available for temporary or permanent free access.
