The broader analysis of greenhouse gases such as CO2, and of other, non-greenhouse gases, such as SO2 and NOx is already very high on the International Maritime Organization’s (IMO) agenda. Various analyses of many aspects of the problem have been and are being carried out and a spectrum of measures are being contemplated. The authors have developed a web-based tool that is freely available online for calculating the exhaust gas emissions (CO2, SO2 and NOx) of specific types of ships under a variety of operational scenarios. It can be used for example by ship owners who need to know both the amount of emissions that their ships produce, and, indirectly, the bunker consumption, in order to choose between alternative scenarios that are both economic and more environmental friendly. In this paper, the algorithm that is behind the web tool as well as the practical importance of this tool are presented. Actual scenarios based on data provided by shipping companies are used and possible ways to incorporate the webtool into actual decision-making are analyzed.
