The purpose of this research is to examine the relationship between green ac counting, environmental performance, firm growth, and firm value in energy companies listed on the Indonesia Stock Exchange. The research uses secondary panel data com prising 45 firm-year observations from nine companies during the 2019–2023 period. Samples were selected using purposive sampling based on the consistency of financial reports, sustainability disclosures, and participation in the PROPER program. Data were analyzed using EViews 12. Green accounting was measured using a GRI-based disclosure index, environmental performance was based on PROPER ratings, and firm growth was measured through changes in total assets. The results show that green ac counting has a significant negative relationship with firm value. Meanwhile, environ mental performance and firm growth do not have a significant effect. These findings sug gest that sustainability efforts must be supported by effective financial alignment to en hance investor perception in capital-intensive sectors.
