“Open Access adds value to research, to the economy and to society. The outputs from publicly-funded research should be publicly available to researchers, but also to potential users in education, business, charitable and public sectors, and to the general public.”

Plan S is an initiative for Open Access publishing that was launched in September 2018. The plan is supported by cOAlition S, an international consortium of research funding and performing organisations. Plan S requires that, from 2021, scientific publications that result from research funded by public grants must be published in compliant Open Access journals or platforms.

“All Irish scholarly publications resulting from publicly funded research will be openly available by default from 2020 onwards and will be accessible on an ongoing basis.”
Research Funders Open Access Mandates
Many funders now require publications, and in many cases data, arising from research to be made available open access. Sherpa Juliet https://v2.sherpa.ac.uk/juliet/ is a searchable database and single focal point of up-to-date information concerning funders' policies and their requirements on open access, publication and data archiving.
These are open access agreements with publishers facilitated by IReL (Irish Research eLibrary) which typically allow corresponding authors from eligible institutions to publish their articles open access immediately on publication. https://irel.ie/open-access/
