European Union requires Open Access: "Money is essential in OA, and only governments are able to provide sufficient funds on a major scale."
This conflates author-pays publishing in "Gold" OA journals with cost-free author self-archiving of articles published in subscription journals ("Green" OA).
No extra money is needed for Green OA self-archiving. It just requires a clear mandate (requirement) to self-archive, by depositing the author's final, peer-reviewed draft in the author's institutional repository immediately upon acceptance for publication. The deposit should be made OA immediately (or after an embargo period whose allowable length should be as short as possible).
Research Councils UK, under the influence of the publisher lobby, has adopted a mandate that prefers to pay for Gold OA, though it also (reluctantly) allows Green OA. Fortunately, however,
HEFCE (Higher Education Founding Council of England) has proposed to mandate immediate deposit of all articles as a precondition for eligibility for evaluation in the Research Excellence Framework (REF), an important source of top-sliced research funding for UK universities.
The EU OA mandate should be for Green OA only, with immediate deposit required (and no embargoes allowed to exceed 6 months). No extra money should be provided for Gold OA. Publication costs today are still being covered in full by worldwide institutional journal subscriptions. So paying for Gold OA today entails double-paying: subscriptions plus Gold OA fees (poached from scarce research funds).
Journal subscriptions cannot be canceled until all journal articles are available by some other means.
Globally mandating Green OA will provide that other means. Then subscriptions can be cancelled, releasing the institutional funds to pay for Gold OA without having to double pay -- and also driving down the price of Gold OA (currently vastly inflated) to fair, affordable, sustainable levels, by offloading all access-provision and archiving onto the worldwide distributed network of Green OA institutional repositories (phasing out the publisher's print and online edition and their costs):
Post-Green Gold OA will be "Fair Gold." Today's pre-emptive, Pre-Green Gold OA is profligate "Fool's Gold."
