Corporate sustainability has become a crucial aspect of business strategy, particularly for multinational corporations (MNCs) aligning their operations with global sustainability goals. The successful implementation of sustainability strategies is often influenced by organizational factors, with organizational culture playing a significant role.  This thesis investigates the influence of organizational culture on the implementation of corporate sustainability strategies within an MNC subsidiary. It seeks to understand how different aspects of organizational culture facilitate or hinder the adoption and execution of sustainability initiatives. As a result, an exploratory research approach is employed, utilizing qualitative methods such as interviews. Through in-depth analysis of data collected from a selected MNC subsidiary, the study identifies key drivers and barriers within the organizational culture influencing sustainability strategy adoption and execution. Findings highlight the significance of leadership support, employee engagement, communication channels, and individual beliefs in fostering a conducive environment for sustainability initiatives. This research provides empirical insights into how organizational culture affects the implementation of corporate sustainability strategies, offering practical guidance for organizations to facilitate the effective implementation of sustainability initiatives.
