The development of a global framework for regulating GHG emissions from shipping is one of the most intensively discussed environmental topics in last decade. In general, shipping is considered an environmental friendly mode of transportation due to its energy-efficiency results. In July 2011 came a first mandatory global GHG reduction measure for the shipping industry. However, market-based mechanisms were also considered, since it is expected that there will be substantial growth in world trade during the next decades. These measures claim to regulate GHG emissions from international shipping in a cost effective and non-discriminatory way while achieving environmental targets and enhancing the sector’s ability to invest in technological improvements. However, stakeholders have serious disagreements about the mechanisms, which seem to bring discussions to a deadlock. The aim of this paper is to provide an inter-subjective view of the current status, based on cause and effect analysis on the conflict areas.
