Air pollution from cruise ships is receiving increasingly more attention. However, the management systems for emissions to air within cruise companies are still insufficiently developed, since the focus is on other environmental factors, such as garbage and wastewater. In order to enhance these management systems, this thesis is exploring a number of aspects that are intended to make air emission management in cruise companies more effective. In order to answer the defined research questions, semi-structured interviews as well as an industry benchmark have been chosen. These interviews have been conducted at a cruise company and at several external stakeholders. During the interviews it has been explored who the main stakeholders of air emissions from cruise ships are and what requirements these stakeholders have concerning air emission management. It has been found that the cultural background of a stakeholder is considered to have an influence on the priority with which environmental issues are perceived. Further, NOX, SOX, PM and CO2 have been identified as the most important pollutants, while NOX, SOX and PM being a problem on a regional basis whereas CO2 is considered to be a global problem. Further, the benefits and concerns related to the installations of continuous emission monitoring systems, that measure a variety of exhaust gases directly in the ship‟s stack and have recently been introduced for marine applications, are explored. This analysis has shown that a CEMS is an indispensable tool for effective air emission management in a cruise company, which provides a number of benefits to the company, given the fact that these systems can prove to operate in a marine environment. Finally, this thesis proposes a KPI system that considers the various demands of all stakeholders, in order to ensure that the data, which a CEMS provides is effectively used in order to ensure continuous emission reductions. The proposed KPI system uses a form of abstraction as well as a differentiation between a ship‟s operational modes in order to provide the KPI user with one single air emission KPI. These KPIs have been designed for each functional level within a cruise company.
