This master thesis has developed a market selection model for the comprehensive assessment and analysis of markets for sustainable packaging solutions. The goal was to create a model characterized by simple handling, attractive design and flexible adjustment possibilities. The theoretical part of the thesis deals with different influencing factors from the areas of internationalization, model conception and selection of criteria. The focus lies on the characteristics of B2B markets as well as market requirements for sustainable product solutions. The model construction as well as the instrument selection are supposed to ensure the greatest flexibility possible in order to analyse a high number of alternatives efficiently as well as to analyse a small number of alternatives precisely. To ensure the operational viability of the model, a large number of potential assessment criteria were identified and summarized in a list thus completing the theoretical part of the thesis. After compiling the model, experts from both the fruit and vegetable sector were consulted in empirical interviews. These interviews and their findings were used in order to evaluate the selected criteria according to their importance. Additionally, they proved to be very helpful for the final optimization of the model. After development had been completed, the model was first applied on a real market selection. The goal was to define three target markets for the forthcoming expansion of the Verpackungszentrum GmbH, a packaging manufacturer from Austria. A total of 21 European countries were analysed on the basis of 16 criteria in order to determine the best alternatives possible. Eventually, three countries, which were comprehensively analysed and found compatible to the company's requirements, were selected. Through the results of the analysis as well as further recommendations, the functionality and the practical applicability of the model was proven perfectly.
