The Computing Methods for CO₂ Emissions in Maritime Transports

Nowadays the global climate changes have determined the international bodies to take measures in order to reduce emissions that contribute to the greenhouse effect. The main component of the exhausting gases produced by diesel engines is the CO₂ emissions, considered responsible for the greenhouse effect appearance. The CO₂ occurrence is largely dependent on the fuel carbon content as used in the diesel engines and further on the fuel consumption. In this context, it is worthwhile considering the maritime transportation activities taking place since 2011 when IMO took steps to reduce the emissions of CO₂ from the exhaust gases of marine diesel engines on ships, enforcing their energy efficiency standards. This paper presents a summary of the main methods for determining the CO₂ masses from the exhaust gases of marine diesel engines. These computation methods highlight usage opportunities from the sustainable management principles point of view, promoting the concept of energy efficiency onboard the ships. The undertaken researches open new perspectives in regulation framework, offering new tools for GHG ship emissions’ monitoring and evidence.
