The papers should report original, previously unpublished findings in the fields of sustainable development of energy, transport, water, food and environment systems, their integration, their technical, environmental,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. The review papers are also welcome if they give a thorough review in a particular narrow field with a deep gap analysis. 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", “review” 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.
