On 4 September 2018, 11 national research funding organisations, with the support of the European Commission including the European Research Council (ERC), announced the launch of cOAlition S, an initiative to make full and immediate Open Access to research publications a reality. It is built around Plan S, which consists of one target and 10 principles.
cOAlition S signals the commitment to implement, by 1 January 2020, the necessary measures to fulfil its main principle: “By 2020 scientific publications that result from research funded by public grants provided by participating national and European research councils and funding bodies, must be published in compliant Open Access Journals or on compliant Open Access Platforms.”
