The Chinese Academy of Sciences (CAS), the world's largest research institution with more than 50,000 researchers in about 100 institutes, plans to stop paying for publishing in more than 30 expensive open-access journals from March 1.[1][2] Particularly affected are prestigious titles such as Nature Communications, Cell Reports, and Science Advances, where article processing fees (APCs) reach at least $5,000 per article.[1][2][3] The global average of APC is around 2000 dollars, therefore some other open-access journals such as PLOS One or Scientific Reports remain available to CAS researchers.[1] The policy prohibits the use of academy funds for these fees, and CAS has not yet officially announced the change.[1][2] The researchers received information from the institution's managers, although they are not authorized to speak about it publicly.[1][3] Each year CAS publishes a "list of warning journals" for high fees or other problems.[2] Similar measures are introduced by other countries, for example the German Research Foundation with an upper limit for APC.[2]
