A lively, vigorous format, aiming to stimulate delegates to actively participate in conference sessions, as well as to promote discussion and blend in of ideas & expertise between different disciplines.

The 9th International Congress on Environmental Geotechnics, which is the premier conference series in Environmental Geotechnics under the Auspices of the Technical Committee “Environmental Geotechnics” (TC215) of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), will be held on 25-28 June 2023 on the beautiful island of Crete in Greece. The conference theme “Highlighting the Role of Environmental Geotechnics in Addressing Global Challenges” will bring together international leaders in environmental geotechnics and will cover a wide range of topics that relate to advances in research and practice with a focus on safeguarding the geoenvironment, energy and resource harvesting, combating climate change and responding to natural hazards. See the conference themes below.
