Forthcoming implementation of international and European environmental regulations, namely Marpol Annex VI and Directive 2012/33/EU, will force ship owners to assess technologies that can allow them to comply with regulation whilst helping them to improve their position in an increasingly competitive market. For the past two years, the team of analysts have worked together in a study leading towards the publication of this report. Our objective has been to analyse which technology would give the best results for the ship owner to comply with environmental regulations concerning emissions from a financial point of view. As a result of this study, different scenarios on technology uptake towards 2030 for the Southern European SSS fleet have been defined.The results published in this report are not definitive predictions of the Mediterranean shipping sector in 2030. We hope to portray a general picture of the most convenient technological options for different kinds of vessels.
