The 5th Annual Conference of the Portuguese Association of Energy Economics (APEEN) is fully dedicated to all aspects of the Energy Transition and Sustainability. Climate change and sustainability are challenging energy systems to new levels of innovation, in terms of technology, regulation and social values. The 5th APEEN conference aims to join leading academic scientists, researchers, innovators and business and social stakeholders, through an interdisciplinary context to present, share and discuss the most recent experiences, research results, innovations and ideas around the multiple themes on Energy Transition and Sustainability. It aims to strengthen ties among academia, industry, regulators, authorities and policy makers, as a contribution to achieve sustainable and carbon neutral energy systems.

The 5th Annual APEEN Conference is organized by CENSE (Center for Environmental and Sustainability Research) from NOVA School of Science and Tecnhology.

Call for papers

Authors are encouraged to contribute to the conference with high quality research describing original and unpublished results through extended abstracts that address the topics of the conference (see templates below). A peer-review process will select the best ones for presentation in the conference (e-poster or oral presentation). All accepted extended abstracts will be published through a Book of Proceedings, with ISBN.

All papers accepted for presentation (oral or e-poster) will have the opportunity to be considered for publication in the following journals: International Journal of Sustainable Energy Planning and Management and Sustainability (Special Issues: Energy Systems Sustainability and Multidimensional Perspectives for Energy Poverty Sustainable Mitigation). The selection will be carried out during the peer review process as well as at the conference presentation stage. Full papers submission will be managed by the editor of each Journal. The final decision for paper publication will be made based on peer review reports by the respective Journal.
