Maritime transport is responsible for about 2.5% of global greenhouse gas emissions representing around 1000 million tons of CO 2 annually. The situation of shipping emissions that strongly depends on future economic grows is aggravated by the fact that global green house gas (GHG) emissions are predicted to increase between 50 and 250% by 2050. This is not compatible with the internationally agreed goal of keeping global temperature increase below to 2 ∘ C compared to pre-industrial levels, which requires worldwide emissions to be at least halved from 1990 levels by 2050. Furthermore, ship owners are facing barriers implementing energy efficiency technologies to reduce CO 2 mainly due to reliability, and financial and economic constraints as well as due to the complexity of change. Energy consumption and CO 2 emissions of ships could be reduced by applying operational measures and implementing existing technologies. Further reductions could be achieved by implementing new innovative technologies. The aim of this study is to compare and review low carbon and advanced technologies that may help to reach international GHG reduction goals. A comparison table describing the different technologies, the estimated capital cost, technology readiness as well as the potential GHG reduction is drawn. The table also indicates if the technology suits better to new projects or to retrofitting. The comparison may help the key players to select the most convenient technology for their new projects. It will also be helpful for conversion of existing vessels.
