The Library of the ELTE PPK considers sustainability and environmental protection issues to be very important in relation to library operations as well. Therefore, it regularly cooperates with the K21 Green Library Team of the K21 Quality Management Committee  of the ELTE Library Council. Among other things the Library participated in the green library survey conducted in the spring and summer of 2018, which primarily examined the ecological sustainability of the institutions.
