This study systematically reviews the integration of Environmental Management Control Systems (EMCS) and blockchain technology and their combined impact on environmental performance and corporate reputation. Using a qualitative systematic literature review approach, this research synthesizes prior studies published up to 2024 to identify key themes, theoretical perspectives, and empirical findings. The results indicate that EMCS plays a critical role in guiding organizational environmental strategies through monitoring, performance evaluation, and accountability mechanisms, while blockchain enhances transparency, traceability, and data integrity in environmental reporting. The synergy between EMCS and blockchain adoption is found to significantly improve environmental performance by reducing information asymmetry and strengthening stakeholder trust. Furthermore, organizations that integrate these systems tend to achieve enhanced reputational outcomes due to increased credibility and sustainability disclosure reliability. However, challenges such as implementation costs, technological complexity, and regulatory uncertainty remain significant barriers.
