Background: Nowadays, digitalization is one of the megatrends with a significant impact, as it changes societies and businesses. A second megatrend is sustainability, consisting of the ecological, economic and social dimension. Its increasing importance for companies can be highlighted, because it is considered as one of the three top priorities of a firm’s management. However, digitalization and sustainability have to be connected due to their potential for transformation and value creation. In the context of logistics, the interrelation of the two megatrends is especially crucial, as digital technologies have the possibility to support logistics to become more sustainable, which, in turn, can lead to overall sustainability of companies. In this connection, particularly intralogistics is a good field of application, since it represents a high percentage of a firm’s logistics costs.

Purpose: The purpose of this study is to identify how digitalization of intralogistics impacts firms’ sustainability and to examine the reasons why some current digitalization technologies have more influence on firms’ sustainability than others.

Method: With respect to the study’s philosophy, the ontological perspective is relativism and the epistemological view is social constructionism. Moreover, this thesis has a multi-method qualitative approach and an exploratory purpose. It follows an inductive reasoning and includes a case study with four cases. Furthermore, the data is collected through semi-structured interviews as well as secondary data and is subsequently analyzed by using the thematic analysis.

Conclusion: The digitalization of intralogistics has, for the most part, a positive impact on firms’ sustainability. In addition, all three dimensions of sustainability are influenced, and a wide variety of effects are identified. Besides, the economic dimension is mainly recognized to be the most impacted one by the digitalization of intralogistics. Moreover, with respect to the current digitalization technologies in intralogistics, they can be used industry-wide. However, the level of effect of digital technologies in intralogistics and the reasons why some current digitalization technologies have more influence than others are company-specific.
