Environmental Management Accounting (EMA) has increasingly developed as an approach for integrating environmental information into accounting practices and managerial decision-making. However, existing studies use diverse concepts and measurements, resulting in fragmented evidence regarding EMA implementation and outcomes. This study aims to map the development, methodological characteristics, applications, and findings of EMA-related research through a scoping review of 30 studies published between 2019 and 2026 across various industries and organizational contexts. The findings indicate that EMA supports environmental cost management, waste management, eco-efficiency, environmental disclosure, environmental performance, and managerial decision-making. Several studies also associate EMA and green accounting with financial performance, firm value, corporate reputation, and sustainability, although the results remain inconsistent. The review identifies key research gaps, including limited standardization of EMA practices, reliance on disclosure-based proxies, small and sector-specific samples, limited use of physical and monetary EMA measures, and insufficient cross-context empirical evidence. Overall, EMA shows substantial potential to strengthen environmental accountability, organizational performance, and sustainability, while further research is needed to improve its measurement and implementation.
