Abstract

Purpose of the study: This study aims to analyze the effect of carbon emission disclosure and the environmental performance ratings of the corporate environmental performance rating program on firm value, both partially and simultaneously, in companies listed on the Indonesia Stock Exchange for the period 2022–2024. Methodology: This study employs a quantitative causal-comparative approach using secondary data from corporate and regulatory disclosures. Carbon emission disclosure is treated as a form of corporate social accountability, reflecting firms’ responses to environmental expectations. Firm value is measured using Tobin’s Q, while environmental performance is represented by the environmental performance ratings, which function as a public policy instrument implemented by the Indonesian government. Statistical analysis is used to examine how public regulation shapes market responses to corporate environmental accountability. Main Findings: The results indicate that carbon emission disclosure does not have a significant effect on firm value. The environmental performance have a negative and significant effect on firm value. Simultaneously, carbon emission disclosure and the environmental performance ratings do not have a significant effect on firm value, indicating that environmental information is not yet a major consideration for investors. Novelty/Originality of this study: This study offers novelty by re-examining the effect of carbon emission disclosure and the environmental performance ratings on firm value using the most recent data from the 2022–2024 period. It assesses whether environmental aspects have been utilized by investors as signals in firm valuation and provides empirical contributions to environmental accounting literature and the formulation of sustainable business policies.

Abstract

Purpose of the study: This study investigates the effect of corporate social responsibility disclosure as a social legitimacy mechanism and profitability on firm value in the mining industry. Methodology: This research employs secondary data derived from annual financial statements and sustainability reports of mining companies listed on the Indonesia Stock Exchange. A causal associative quantitative approach with purposive sampling was utilized. Data analysis involved multiple linear regression, classical assumption testing, and descriptive statistical analysis, processed using IBM SPSS Statistics software. Main Findings: The results show that corporate social responsibility disclosure has a positive and statistically significant effect on firm value in the mining sector. In contrast, profitability does not have a significant partial effect on firm value. However, when examined simultaneously, corporate social responsibility disclosure and profitability jointly have a significant influence on firm value. Novelty/Originality of this study: This study offers originality by examining corporate social responsibility disclosure based on the Global Reporting Initiative Standards 2021 as a mechanism of social legitimacy in explaining firm value in the mining sector. Using recent panel data from 2021 to 2024 in Indonesia, the findings demonstrate that corporate social responsibility disclosure plays a more decisive role than profitability in shaping firm value, particularly in industries with high social and environmental exposure.
