PENGARUH PENGUNGKAPAN NILAI LINGKUNGAN, TANGGUNG JAWAB SOSIAL, DAN TATA KELOLA TERHADAP NILAI PERUSAHAAN (Studi Empiris pada Perusahaan Migas Batu Bara yang Terdaftar di Bursa Efek Indonesia Tahun 2023)

This study examines the effect of environmental value disclosure, corporate social responsibility (CSR), and corporate governance on firm value in the oil, gas, and coal sector listed on the Indonesia Stock Exchange (IDX) in 2023. Using an explanatory quantitative approach, the research analyzed 54 companies selected based on PROPER awards from 2022–2023. Environmental value disclosure was measured through PROPER ratings, CSR through GRI G-4 indicators, and corporate
governance through GRI 200. Firm value was represented by Price to Book Value (PBV). Multiple linear regression analysis revealed that all three independent variables had a significant positive effect on PBV. Transparent environmental disclosure signals strong management quality and longterm orientation, CSR initiatives enhance stakeholder trust and reputation, and robust governance reduces information asymmetry, improving investor confidence. These findings underscore the importance of ESG (Environmental, Social, Governance) factors in shaping market perception and enhancing sustainable corporate valuation in high-impact industries.
