The 11th Conference on Sustainable Development of Energy, Water and Environment Systems – SDEWES Conference, to be held in Lisbon in 2016, is dedicated to the improvement and dissemination of knowledge on methods, policies and technologies for increasing the sustainability of development by de-coupling growth from natural resources and replacing them with knowledge based economy, taking into account its economic, environmental and social pillars. One of the main issues of the coming decades is to improve efficiencies by integrating various life supporting systems, using waste from one, as resource in other, and in exact moment when it is beneficial to all, integrating electricity, heating, cooling, transport, water, buildings, industry, forestry and agriculture systems. Sustainability being also a perfect field for interdisciplinary and multi-cultural evaluation of complex system, the SDEWES Conference has at the beginning of the 21st century become a significant venue for researchers in those areas to meet, and originate, discuss, share, and disseminate new ideas.

The papers must report original, previously unpublished findings in the fields of sustainable development of energy, transport, water, food and environment systems, their integration, their technical, environmental,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 abstracts and papers must be written in English. 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 in English, between 1500-2500 characters long.
