Hungarian Academy of Sciences:

"The researchers and employees of the [HAS] - including researchers of the subsidized research units and Momentum research groups - should make their scientific publications Open Access. Open Access could be achieved by i.) self-archiving in institutional or discipline-based repositories, ii.) publishing them in Open Access journals or in hybrid journals offering paid Open Access. The Mandate is obligatory for all scientific publications submitted for publication after January 1st, 2013. Open Access for scientific publications submitted before 2013, or published already, is recommended (through repositories)."  

European Science Foundation:

"Funders should adopt a clear statement in favour of open access, provide a mechanism for funding gold open access and employ clear and binding mandates for green open access."
