Sustainability has become an important strategic driver for the textile industry. In order to measure and communicate sustainable data about a product to the consumers, various labels and tools have recently been introduced to the market. Throughout this jungle of eco-labels and sustainable claims, an industry group was founded with the aim of harmonizing sustainability measurement standards for textile products. This international harmonization organization, the ‘Apparel Coalition’, developed emerging standards together with the major global textile industry players. Even though their agreed measures were shared across the industry, limited studies have been done until now on how to combine the harmonized sustainability data requirements with the different corporate IT landscapes. Therefore, a framework called the ‘House of sustainable garment assessment’ was developed in cooperation with the National Taiwan University within the scope of this thesis, based on strategic requirement assessment methods and Risk Management considerations. The integration of this framework into the real company setting of the adidas group was tested thoroughly and the results were discussed. Finally, managerial implications and future paths were also specified.
