The publication represents a compilation of smart and sustainable projects from over 30 islands across 13 European countries, currently under implementation or in the phase of maturation, which were showcased during the 1st Smart Islands Forum that took place on 21 and 22 June 2016 in Athens, Greece. The Forum was organized at the initiative of the DAFNI Network of Sustainable Aegean and Ionian Islands and the Aegean Energy Agency, with the support of the Friedrich-Ebert-Stiftung, the Central Union of Municipalities of Greece and the Covenant of Mayors Office. The report presents the profiles of the majority of European islands involved in climate responsible and innovative projects, providing also an overview of the technologies deployed.
