The acceleration of environmental issues, the depletion of natural resources, and the global climate crisis have rendered the concept of sustainability an inevitable common ground for individuals, global policymakers, and the business world. The sustainable consumption approach, built upon the principles of rational resource utilization and the preservation of future generations' rights, holds a central position in mitigating ecological degradation. Concurrently, the ongoing digitalization process reshapes the information acquisition and consumption tendencies of the masses through channels such as social networks, content strategies, artificial intelligence, data analytics, and smart chatbots. This study aims to address the potential of these digital marketing instruments to transform and disseminate sustainable consumption patterns through a holistic approach. Adopting a systematic literature analysis model, the research scans current, high-quality, and directly relevant resources indexed in Web of Science, Scopus, ScienceDirect, and Google Scholar platforms. Generative artificial intelligence technologies were functionally utilized during the classification of documentation and the optimization of textual flow, while all conceptual inferences and syntheses were carried out by the researcher. The findings indicate that sustainability-oriented communications conducted by organizations on digital channels strongly trigger social environmental awareness, eco-friendly product choices, and rational purchasing practices. By proving the critical role played by digital marketing frameworks in serving macro-level sustainability visions, this study intends to guide both the academic literature and field professionals.
