A Systematic Literature Review of Carbon Information Disclosure on Value Effect

Objective: This study aims to investigate the value effects of carbon information disclosure, with the goal of understanding its motivations, influencing factors, and consequences. As corporate environmental sustainability and low-carbon transitions gain global attention, carbon information disclosure serves as a key mechanism for organisations to fulfil their environmental commitments, aligning with SDG 13 Climate Action. Theoretical Framework: This study is grounded in stakeholder theory and signalling theory, which provide a solid foundation for understanding how carbon information disclosure influences firm value. These theoretical perspectives help explain how enterprises respond to external pressures and use disclosure as a strategic tool to signal environmental responsibility. Method: A systematic literature review was conducted, screening and analysing 81 papers to synthesise existing research on carbon information disclosure. The review process involved identifying relevant studies, categorising key findings, and examining the empirical evidence supporting the relationship between carbon information disclosure and firm value. Results and Discussion: The findings reveal that carbon information disclosure has significant value effects, influenced by factors such as regulatory pressures, market expectations, and corporate governance. The discussion contextualises these findings within the theoretical framework, highlighting the complexities of disclosure practices and their implications for firms. Limitations and potential research gaps are also considered. Research Implications: The study offers both theoretical and practical contributions by providing insights into how carbon information disclosure can enhance firm value and inform corporate sustainability strategies. Policymakers, investors, and business leaders can leverage these findings to improve disclosure practices and regulatory frameworks, thus supporting the achievement of SDG 13 Climate Action. Originality/Value: This study contributes to the literature by systematically analysing the value effects of carbon information disclosure, offering a comprehensive overview of its drivers and consequences. The findings provide a foundation for future research and inform sustainable corporate decision-making, supporting the global climate action agenda.
