The rapid advancement of information and communication technologies, along with innovations in hardware, storage, and software driven by globalization and digitalization, have led to the creation of a vast network of interconnected devices significantly contributing to the exponential growth of data. As data centers continue to grow, they contribute increasingly to global carbon emissions, highlighting the need for organizations to incorporate sustainability tactics into their strategic objectives. The purpose of this paper was to investigate the key knowledge management (KM) strategies to be applied as an organizational sustainability tactic. Data across multiple industry sectors were collected and 539 responses were analyzed through a factor analysis in SPSS and by a sectorial standard deviation analysis. Two KM strategies as sustainability tactics were derived, (1) knowledge conversion and application, and (2) knowledge capture and transformation. These findings offer a suggestion for organizations seeking to align their KM practices with sustainability goals, while the sectorial variation in responses suggest sector-specific maturity and emphasis on how KM is operationalized for sustainability outcomes. These disparities imply that while some sectors are advancing in leveraging dark data through structured KM approaches, others may require more tailored interventions, awareness programs, or capacity building to fully harness knowledge for sustainability and data-driven value creation.
