The International Conference on Environmental Science and Technology is one of the worldwide leading environmental conferences. This biennial conference brings together engineers, scientists, researchers, students, managers and other professionals in order to address and discuss emerging environmental issues. The conference is supported by the multi-disciplinary Global NEST (Network of Environmental Science and Technology); an international scientific movement that has been successfully developing for the last 24 years with members from more than 60 countries. Global NEST is an international scientific movement focusing on innovative environmental issues.

The success of this conference reflects the critical environmental topics that are discussed as well as the quality of the presented papers. All the papers that are selected for either oral or poster presentation undergo a review process. As a result of the improving quality of the papers in previous conferences, the proceedings of the 7^th up to the 12^th CEST have been included in databases, such as Science Citation Index (ISI) and SRCosmos.

A number of presented papers will also be considered for inclusion in special issues of the "Global NEST Journal", “ European Water”, “Desalination and Water Treatment Science and Engineering”, “Chemosphere ” and “Journal of Hazardous Materials” amongst others after the normal peer review process of the journals.

The 13^th International Conference on Environmental Science and Technology will be organized in Athens from 5 - 7 of September 2013 under the auspices of the CITY OF ATHENS and the Hellenic Recycling Agency (HRA).
