I doubt the EU will take the lead on such a thing; the EU has a lot less tolerance for new technologies upending traditional institutions than the US. European universities basically require professors to publish in journals owned by a handful of publishing companies, which has served to cement the power of those publishers (American universities tend to be a little more open minded about new publishing models in my experience). I have heard European researchers complain that people were citing the arxiv version of their papers rather than the "official" version -- it made it harder for them to advance their careers.
