Theoretical Framework: In this topic, the main concepts and theories that underpin the research are environmental accounting and stakeholder theory, providing a solid basis for understanding the context of the investigation.

Research Implications: These findings indicate that while green accounting is essential for ensuring long-term sustainability, its present adoption and acknowledgement in Nigeria may need further progress in order to fully achieve its projected advantages.

Originality/Value: The present study enhances the current body of knowledge by offering an in-depth examination of the influence of green accounting practices on the value of companies in Nigeria. While there has been research on green accounting practices, there seems to be a gap in the African setting as most studies are focused on developed nations and not emerging economies.
