Abstract
In the last 10–15 years, Open Access has become a shared vision of many if not most of the world’s national and international research councils. Open Access as a principle is very well established in the international discourse on research policies; however, Open Access as a practice has yet to transform the traditional subscription-based publishing system, which is as vigorous and prosperous as ever, despite its inherent restrictions on access and usage and its remarkable detachment from the potentials of a 21st century web-based publishing system. OA2020 is a transformative initiative trying to bring a new approach to the transactional side of the publishing system and the ways in which its cash flow is organized. Publishing and financial data are brought together in a way to demonstrate that such a switch would indeed be feasible. OA2020 lays out the path for how this transformation could happen so that Open Access to research results would finally be a reality from the moment of their publication.
Since 2003, the Berlin Conferences have been nodes in a journey whose rationale is to achieve Open Access (OA) in journal publishing by transforming outdated commercial practices into a post-subscription business model. Until very recently, the principal focus of this initiative has been on generating awareness, creating mandates and devising various practical measures, all predicated on an effort to
Rebooting the approach to OA
Our revised aim is to create the conditions in which OA supports researchers in every aspect of their practices, from accessing existing outputs to publishing the results of their own research. From this perspective we can see that it is not the researchers who should be obliged to change; rather, it is the publishing system and its underlying business model that needs an overhaul. For intellectual and career reasons, researchers will naturally aim to publish in established, prestigious journals, so – along with the whole business of scholarly publishing – these must be the focus of our persuasive efforts so that the OA project can inspire an industry-wide shift in the approach to journal-publishing.
Until recently, the entrenched practices in academic publishing have led all sides in the industry to view the current business model as inevitable. The traditional subscription system involves a cash flow philosophy that is predicated on inherent restrictions on use/reuse rights. The task ahead is to induce an inversion of this, such that the cash flow is legitimised by an offer of publication services that deliver a truly OA environment. By shaking off old habits of mind we can deconstruct the functions of publishing to show that registration, certification, dissemination and (possibly) archival record are at the core. We believe that
Articulating this goal inevitably provokes discomforts and challenges, since these proposals are counterintuitive to the knowledge and experience of many (or even most) of those in positions of authority: library directors, heads of acquisitions departments, senior academics in institutions of learning. Typically these leaders have been hampered in their strategic analyses by the insufficient gathering of data or other evidence within their institutions and by understandable anxieties about the financial implications of a transition to OA. The transformation must of course be based on a demonstration of its financial viability; there will need to be pilot programmes and the elaboration of the necessary workflows; and a large international coalition will need to coalesce to commit to the transformation to OA and develop a transition plan.
Bringing data and analysis to the OA debate
To allay fears about an insufficiency of resources or that an OA world would be even more expensive than the current subscriptions system, the Max Planck Digital Library (MPDL) published a white paper in the spring of 2015 that has become a reference document for the OA movement [1,2]. We drew on data from ten years-worth of publishing from all over the world, paying particular attention to the issue of corresponding author share, which is crucial to the viability of an article-processing charge (APC) scheme. Our claim, based on current global annual operating figures, is that there is sufficient ‘money’ in the system to finance the outputs of scholarly communication in an OA world
The starting-point of our analysis is the figure of €7.6 billion as the total global budget.1 The subscriptions-based market produces 1.5 million scholarly articles on the World of Science (WoS) index, or up to 2 million overall; this implies a cost-per-article of approximately €5,000 for WoS articles, or €3,800 overall. By contrast we note that, in an observably consistent picture, the existing APCs are substantially less than €2,000.2 If 2 million research papers are published at an APC of €2,000, then the resultant total of €4 billion gives a 45% buffer within the current system, allowing significant investment in new and improved services, remaining subscriptions, as well as other adjustments. This overview is summarized in Fig. 1.

The financial dimensions of the global scholarly journal publishing.
In the past, various parties have presented cost projections that are based on naïve or inaccurate analyses. An important dimension of our work is the recognition of the need to de-duplicate the raw data that is drawn from bibliographies and institutional repositories so as to reflect the reality that research is increasingly co-authored: by co-authors from different institutions and sometimes beyond national borders. While authors may be recorded recurringly in the bibliographies of all the home institutions, the costs of publishing services are a one-time event. In terms of the share of corresponding author papers, there are differences around the world. In Europe, the proportion is approximately 70%; in the larger and more insular contexts of China and the US, the share is higher, while in smaller or less research-intensive countries the share is lower.

Cost projections for a full-fledged OA scenario in Germany.
Our analysis of the publications volumes in Germany and Great Britain – which are remarkably close to each other – show that whether one relies on a conservative view of publishing costs (i.e., assuming €2,000 per publication) or an actual average APC (i.e., taking the €1,300 from the Open APC Initiative), these countries’ spending budgets are currently substantially greater than the costs of an OA model (Figs 2 and 3). Experts assess the spending of the German higher education institutions for their journal subscriptions to be in the range of €200 million per year. For the UK, those estimates vary from £160 million per year (according to Jisc Collections) to £192 million (according to Research Libraries UK).
We conclude that even for research-intensive countries with high publication volumes an orderly transition to OA publication charges is without financial risk, and will free up resources for additional investment in new services.

Cost projections for a full-fledged OA scenario in the UK.
There are many parallel initiatives around Europe that support OA in various forms, but these are not yet connected to a shared goal. This fragmented impetus shows that this is a timely moment to develop an international transformation programme to align and capitalise on the diverse efforts being made to create an open access environment.
The Berlin 12 Conference held in December 2015 convened 100 delegates from 19 countries, along with some international organizations, and had two principal outputs in support of the proposed transition to OA.3

The goal for all sides in academic publishing is to bring about an orderly transformation of the business of academic publishing: established practices of journal publishing will continue while ‘disruption’ will occur only by a strategic rethinking of the financing. Overall, the OA initiative may be expected to inspire the creation of new and better ways of registering, certifying, disseminating, and archiving the fruits of scholarship in the 21st-century’s digital world.
