The European University Association (EUA) represents more than 850 universities and national rectors’ conferences in 49 European countries. Through continuous interaction with a range of other European and international organisations, EUA ensures that the independent voice of European universities is heard. EUA takes a comprehensive approach to the transition to Open Science. With this, EUA aims to continue to help its members transition to Open Science, contribute to the development of national, European and institutional policies conducive to the mainstreaming of Open Science, and encourage universities to play a more proactive role in the regulatory and financial frameworks shaping this process. In particular, EUA advocates for a just scholarly publishing ecosystem that is transparent, diverse, economically affordable and sustainable, technically interoperable, and steered by the research community.
