The Organizing and Scientific Committee of CEST2021, invites you to participate in the 17th International Conference on Environmental Science and Technology (CEST2021). The conference will be held in Athens, Greece from 1 to 4 September 2021.

The conference is organized by the Global Network of Environmental Science and Technology jointly with the University of the Aegean (Greece) and the National and Kapodistrian University of Athens (Greece). CEST2021 is academically supported by the University of Salerno (Italy), the University of Cincinnati (USA) and the Imperial College London (UK) as well as a group of distinguished scientists – the members of the Conference Scientific Committee.

CEST2021 is under the patronage of UNESCO’s Water Assessment Programme, International Water Association (IWA), A.C.

CEST series proceedings have been included in databases, such as Science Citation Index (ISI) and since 2015, most of the presented papers are also published in cooperating journals - in special issues.

Proceedings of 2021 will be published in the Springer ASTI Book Series (indexed in Scopus):


The proceedings of our previous event have also been accepted for publication in Springer ASTI Book Series. They are in press and we expect to have the book published in a couple of months.
