Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)

"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

18th SDEWES conference was held from 24 - 29 September 2023 in Dubrovnik, Croatia, and it brought together 646 scientists, researchers, and experts in the field of sustainable development from 58 countries and six continents, out of which 507 attended onsite and 137 online.

We have listened to 568 oral presentations and had the chance to see 56 poster presentations. There were 51 regular sessions onsite and 71 online with 13 special sessions plus four keynote plenary lectures and three panels given by some of the most distinguished experts in the field.

This year we continued with the tradition within the onsite conferencing, by organizing the Project Exchange Event which aroused a lot of interest. 28 projects were presented, and many were interested in hearing about them.

We hope you were as happy as we were as we again had the chance to meet, mingle and share new ideas in person.

All the photos, presentations, and videos of the most important events, as well as participants’ insight on the SDEWES 2023 are available on the conference website, but also at our SDEWES Talks Please feel free to share it with your colleagues and for more information and updates, look for #sdewes and follow us on social media, but also at our SDEWES Talks Please feel free to share it with your colleagues and for more information and updates, look for #sdewes and follow us on social media:
