The Society for Ecological Sustainability, SES, is situated in Bad Mitterndorf, Austria, and is a non-profit organization. Its purpose is to spread eco-philosophical ideas and scientific-ecological knowledge as well as to develop concepts of ecological, social and economic sustainability.

During 2000 and 2006 the scientific journal Natur und Kultur: transdisziplinaere Zeitschrift fuer oekologische Nachhaltigkeit was published by our society. The vast majority of the papers published in this journal (in German) can be found on our online library.

Dr. Thomas Seiler, the manager of SES is responsible for our online library.
