On 23 November 2023 the ten ENLIGHT Rectors endorsed joint Open Science principles on the occasion of the ENLIGHT General Meeting in Uppsala. With the joint statement ENLIGHT aims to create a common basis for an Open Science culture. ENLIGHT is committed to implementing an ‘open by default’ approach to online resources, for its teaching, research, outreach and engagement activities, for the benefit of science and society. As an enabler of the quality and impact Open Science plays a key role in the ENLIGHT universities’ higher education transformation agendas. It is a powerful driver for transparency, accountability and reusability and increases collaboration. Main elements of our joint statement are the broad promotion of Open Science with training and sharing of good practices, the importance of FAIR data principles, unrestricted Open Accesss to publications, the support of Open Education materials and Responsible Research Assessment.
