Cancellation policy: Cancellations or any refund requests must be received in writing before May 28, 2026 in order to obtain a refund minus a 100 EUR administrative charge. After May 28, 2026 refunds are not available, sorry, no exception. Cancelled papers will not be published in Proceedings and will not be invited in the special issue.
No show policy: Authors which do not participate in the Conference, or who participate but do not present their paper according to the guidelines, will have their paper cancelled and the paper will not be published in the Proceedings and will not be publishable in a special issue of any of the journals. In case of no show fee refund is not possible.
Online fees policy: Authors that settle an online fee will present through video or audio narrated presentations on our virtual conference platform with the same publishing policy as if presented in person. Authors will have to present online also in the case the conference is held on-site. Authors that pay an online fee but decide to attend in person will have to settle the fee difference (top up fee). Authors that pay or have paid a regular fee but choose to present in an online mode will receive a SDEWES credit in the amount of their fee difference that may be used for any future SDEWES Conference.
The deadline for the above-mentioned changes will be the same as the cancellation/refund deadline.
Participants that need visa are kindly asked to settle their fee before April 2, 2026, since after that date the time will be too short for visa formalities (see visa page).
