The energy sector is characterized by high environmental risks; therefore, transparency in environmental cost management and compliance with environmental regulations have become essential factors in strengthening investor confidence. This study aims to examine the effect of Green Accounting and environmental performance on firm value in energy sector companies listed on the Indonesia Stock Exchange during the 2022–2024 period. This research employed a quantitative approach using secondary data obtained from annual reports, sustainability reports, and PROPER data. The sample was selected using a purposive sampling technique, resulting in 54 observations. Data were analyzed using multiple linear regression with the assistance of SPSS software.
