Emission inventory assessment for a container vessel

This paper presents estimates of exhaust emissions from a container vessel during its voyages by using current best-practice inventory methodology. Emission estimates are performed for both criteria air pollutants and greenhouse gases. Two approaches, power-based and fuel-based, are applied for emission calculations, where the former involves multiplying power-based emission factors by engine power consumptions and the latter utilizes fuel based emission factors with fuel usage data. With the use of latest emission factors and real data on vessel activity profiles, our emission estimates provide better representation of the actual vessel emission performance. Moreover, good consistency between power-based estimates and fuel-based estimates proves reliability in emission inventory results.
