The papers must report original, previously unpublished findings in the fields of sustainable development of energy, transport, water, food and environment systems, their integration, their technical, environmental, economic and social perspectives. All papers will be reviewed under the direction of the International Scientific Committee by the Scientific Advisory Board. The papers with archival value (archival papers), meaning those that contribute significantly to the state of the art and report final results of research, with proper literature review, will be thoroughly reviewed and will be candidates for publication consideration in special issues of several archival journals. The papers that report work in progress without significant contribution to the state of the art, and those lacking a thorough literature review, are invited as conference papers, and will receive less stringent review. Authors are invited to offer suggestion on classification of their papers as "archival" or "conference", when submitting them.

Authors (corresponding author) willing to present a paper should submit an abstract, between 1500-2500 characters long.
The archival abstracts and papers must be written in English, while conference abstracts and papers will also be accepted in Portuguese and Spanish.

Abstract preparation and submission instructions
An abstract is an extremely important part of the paper because it summarizes the entire paper; it is the public’s window to your work and must allow the reviewers to make an intelligent decision about its acceptance. Its typical composition should be:
Motivation for the paper
Objectives
What was done
How it was done and validated
Major results
Conclusions
In writing the abstract, be quantitative, write it clearly and in good English (or Portuguese or Spanish), and do not exceed the imposed 1500-2500 characters length limit.

References
We believe that it would be very useful if the authors thoroughly reviewed the papers that have already been published in partner journals in special issues dedicated to the SDEWES conference series. Such an effort would not only improve the quality of your manuscript, but also promote the awareness of the available information resources that exist in the structure of the SDEWES conference series.

Paper submission, presentation and deadline rules
Each paper to be published in online Proceedings and in special issues of journals will have to be presented at the Conference by one of the authors (presenting author). The papers will not be allowed to be presented by those who are not its authors. Papers not presented will not be published in the online Proceedings and will not be invited in special issues, no matter what the reason for not presenting them is. Each participating author will be obliged to present one paper orally at the Conference. Any additional papers by the same author may be presented in the poster sessions.

Types of contributions:

The papers with archival value (archival papers), meaning those that contribute significantly to the state of the art and report final results of research, with proper literature review, will be thoroughly reviewed and will be candidates for publication consideration in special issues of several archival journals (among others Energy, Applied Energy, Journal of Cleaner Production, Energy Conversion and Management, Renewable and Sustainable Energy Reviews, International Journal of Hydrogen Energy, Journal of Environmental Management, Thermal Science, Waste Management & Research, Clean Technologies and Environmental Policy, Journal of Sustainable Development of Energy, Water and Environment Systems).
Manuscript template with instructions is available to all corresponding/presenting authors of accepted abstracts after logging-in the conference submission system.
