The Effect of Sustainability Report Disclosure on Firm Value With Growth and Leverage as Control Variables

This study examines the effect of sustainability report disclosure on firm value in energy sector companies listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. The background of this research is based on the growing global awareness of the importance of sustainable business practices and the strategic role of the energy sector in the transition toward a low-carbon economy. The research adopts a quantitative approach with a purposive sampling method, resulting in 16 companies that consistently published both annual and sustainability reports. Sustainability disclosure is measured using the Global Reporting Initiative (GRI) 2021 standards, which cover economic, environmental, and social aspects. Firm value is measured using Tobin’s Q ratio as a market performance indicator. The analytical techniques employed include descriptive statistics, classical assumption tests, and simple linear regression using SPSS software. The results show that sustainability report disclosure has a positive and significant effect on firm value. These findings indicate that transparency in sustainability-related information can enhance market perception, build corporate reputation, and contribute to increased firm value—especially in the face of global sustainability demands and investor preferences toward ESG (Environmental, Social, and Governance) aspects.
