Recent studies present that vessels’ energy consumption and CO2 emissions could be reduced by up to 75% by applying operational measures, by proceeding to actions on efficiency improvement and by implementing existing technologies. Additionally, further reductions could be achieved by implementing new technologies (3rd IMO Green House Gas study 2014).
These kind of studies have led IMO and EU to adopt regulations for monitoring and reporting the CO2 emissions and the Energy Consumption of the Maritime Industry, e.g. EU MRV regulation, SEEMP, etc., with new regulations already on the way.
