Open letter on Plan S in Horizon Europe – CESAER

“Recalling our recent position Open Access in Horizon Europe, the leading universities of science and technology united in CESAER remain strong supporters of open science and open access to scientific publications.

We value the leadership that the European Commission and the European Research Council (ERC) have shown on these important topics, including in their support of Plan S which we also fully support.

It was therefore with surprise that we learned of the ERC Scientific Council’s abrupt withdrawal of their support from Plan S, despite their support since its inception, which was also reiterated last year.

With this letter, I reiterate our association’s strong support for achieving full and immediate open access. We firmly believe that Plan S is an important step towards achieving this goal, as expressed in our position Open Access in Horizon Europe.

We call upon the European Commission to continue their leadership in open science and open access, and we look forward to the full implementation of Plan S in the model grant agreement for Horizon Europe….”


“Recalling our position paper ‘CESAER going towards Open Science’ and ‘Roadmap towards Open Access’, the universities of science and technology united in CESAER are proponents for open science and open access to scientific publications. We support the transition towards making open science the modus operandi in Horizon Europe. We acknowledge the laudable efforts by cOAlition S – a group of national research funding organisations with the support of the European Commission and the European Research Council – to ensure immediate open access to scientific publications and we support ‘Plan S’. In line with our previous statements and our mission, aims and values, we herewith present our advanced position on open access in Horizon Europe.

We support the principles behind Plan S stating that researchers (or their universities) should retain full rights to their scholarly works. For example, any ‘copyright transfer agreement’ where researchers and universities hand over their rights (for their scholarly work or their research data) must be avoided. The retention of rights by researchers and universities is vital as it enables the full utilisation of research outcomes in diverse efforts across all areas of research, education and innovation. We further note the ongoing developments across Europe on copyright laws with open access amendments, such as the Dutch Taverne Amendment and similar efforts in Belgium, Germany, France and other countries. These developments help safeguard the rights of researchers and universities, and we therefore strongly encourage their further deployment. We call on the European Commission to propose EU legislation to give researchers the nonwaivable legal right to share publicly funded and peer-reviewed research findings without embargoes….”
