This study explores how social media–driven green marketing shapes sustainable consumer behavior through a systematic literature review. As concerns about sustainability intensify alongside rapid digital engagement, social media has emerged as a crucial platform for communicating environmental initiatives and influencing consumer responses. Despite this relevance, existing studies remain fragmented across theoretical, contextual, and methodological perspectives, limiting a holistic understanding of the topic. Using the PRISMA approach, this research reviews 42 empirical articles sourced from the Scopus database and analyzes them through the TCCM (Theory–Context–Characteristics–Method) framework. The findings show that most studies rely on intention-based theories, particularly the Theory of Planned Behavior, although there is a growing shift toward integrating social, psychological, and technology-oriented approaches. From a contextual standpoint, the literature is largely concentrated in Asian regions and younger demographics, which restricts broader generalization. Furthermore, results indicate that social media–driven green marketing does not directly affect sustainable behavior but works through important psychological mediators such as trust, engagement, and perceived value. These factors significantly influence how consumers interpret and respond to environmental messages online. The effectiveness of such marketing strategies is also shaped by cultural and demographic differences, making context a critical factor. Methodologically, most studies employ cross-sectional surveys and structural equation modeling, limiting the ability to capture causal and dynamic relationships. Overall, this study provides a structured synthesis, highlights research gaps, and suggests future directions, including cross-cultural analysis, stronger theoretical integration, and more rigorous research designs.
