1. Introduction
In the previous decade,
Friedman (
1970) posited that the primary focus of businesses is to expand shareholder value; spending on socially conscious initiatives detracts from this goal. However, concerns about social and environmental issues have recently undergone a paradigm shift. In the most recent KPMG survey conducted in 2022, 96% of the world’s largest 250 companies are now reporting on sustainability, establishing it as a regular business practice (
K.P.M.G., 2022).
The increased interest in ESG (environmental, social, and governance) among scholars has inspired the production of academic write-ups assessing the impact of ESG initiatives on business risk reduction. For example,
Fransisca et al. (
2025) and
Bani-Khaled et al. (
2025) find that ESG compliance enhances corporate efficiency and reputation, thus lowering loan and equity costs. This implies that ESG compliance helps mitigate business risk, leading creditors and investors to lower their expected returns (
Liu & Lee, 2025).
Al-Issa et al. (
2022) and
Chua and Byun (
2025) contend that firms with significant ESG engagement establish efficient supply chains and operating models, earning a competitive advantage that translates into greater financial and operational success. This suggests that businesses with appropriate ESG practices have a lower overall risk profile (
Amuda & Saka, 2025), which ensures firms’ financial stability, thus making them more attractive to investors (
Wedajo et al., 2023).
Rong and Kim (
2024) argue that ESG disclosure enhances the information environment of businesses by reducing information asymmetry, thereby increasing stock liquidity and boosting investors’ confidence.
Huang et al. (
2023) and
S. Chen et al. (
2023) assert that non-financial reporting reduces the likelihood of environmental litigation, making companies less susceptible to litigation risk, particularly with regard to environmental harm. Taken together, recent studies indicate that ESG initiatives play a crucial role in mitigating a firm’s business risks.
Sustainability reporting in Malaysia has undergone a lot of changes since its official establishment. In October 2015, Bursa Malaysia required all listed issuers to report on their sustainability activities in the form of a ‘Sustainability Statement’ in their annual reports under Practice Note 9 (PN9) of the Main Market Listing Requirements. This meant companies had to be accountable for how they manage significant economic, environmental, and social (EES) risks and opportunities. In 2021, Bursa Malaysia released a Sustainability Reporting Guide (Second Edition), along with a comply-or-explain rule for listed issuers to follow a globally recognized sustainability framework (such as the Global Reporting Initiative (GRI) or the Task Force on Climate-related Financial Disclosures (TCFD)), shifting from general disclosure to more standardized and robust reporting. Again, in 2024, the Bursa Malaysia published an expanded sustainability reporting requirement, requiring publicly listed corporations to adhere to IFRS Sustainability Disclosure Standards as the basis for sustainability reporting beginning in 2025. The IFRS Sustainability Disclosure Standards require all listed issuers to include sustainability disclosures in their annual reports. The exchange’s goal is to improve sustainability management responsibility by requiring enterprises to use globally recognized criteria to manage their sustainability-related risks and opportunities (SROs). The amended rules are meant to promote organizational resilience by making it easier for investors to compare sustainability initiatives across organizations. According to KPMG’s 2024 Survey on Sustainability Reporting (
K.P.M.G., 2024), all of Malaysia’s top 100 corporations currently disclose their ESG initiatives through sustainability reporting.
A key question in this changing environment is whether the external audit process is affected by a company’s commitment to ESG initiatives. While all listed companies and new applicants are required to obtain an independent auditor to audit their financial statements, the relationship between material sustainability risks and financial audits is a topic that warrants further research in the Malaysian context. Audit fees directly correspond to how the auditor perceives the level of risk involved, as well as the amount of work needed to perform the audit (
K. Zhang et al., 2023). According to studies, ESG disclosures can impact audit fees in two ways. On one hand, it can reduce the perceived risk of auditors by lowering information asymmetry, which then decreases audit fees (
Yu et al., 2024). On the other hand, it can increase the effort and complexity of the audit, which can increase audit fees, due to additional non-financial information that needs to be assessed and validated (
K. Zhang et al., 2023).
Malaysia’s ownership pattern adds a layer of complexity to the market, as it reveals a sizable share of institutional investors holding more than 5%. These influential shareholders are increasingly concerned with ESG disclosure, viewing it as crucial for long-term value creation and risk mitigation (
Abdelrahman Adam Abdalla et al., 2024). It remains to be empirically tested if their presence imposes pressure that is translated into stronger audit work for the companies performing sustainability activities, perhaps to protect their investment from ESG-related risks.
The objective of this paper is twofold. First, this study aims to ascertain if audit fees are influenced by the ESG disclosure based on the context of Malaysia. The growing global emphasis on business sustainability has introduced new dimensions to audit risk assessment (
K. Zhang et al., 2023). Specifically, studying the relationship between ESG disclosure performance and audit fees provides insights into how auditors perceive and price the risks associated with a client’s ESG activities and disclosure practices (
Y. Li & Meng, 2025).
Next, this paper aims to analyze the role played by institutional owners in influencing the nexus between ESG disclosure performance and audit fees. The substantial shareholdings of institutional investors provide both the incentive and the power to demand the quality audit of a non-financial disclosure, which subsequently influences audit complexity and costs.
This study makes several contributions to the literature. Firstly, by examining the Malaysian context, this study provides valuable insights into how auditors in an emerging economy respond to sustainability disclosures.
Secondly, it enriches the literature on ESG reporting by exploring the role of institutional investors. Previous authors, such as
Du et al. (
2020),
García-Sánchez et al. (
2020), and
Moalla and Dammak (
2023), have attempted to establish a connection between ESG disclosure and audit fees and reach different conclusions. The absence of a moderating factor could be one of the contributing factors to the mixed outcomes. The present study introduces institutional ownership as a key moderating variable to resolve these ambiguities.
Thirdly, the capital markets in emerging economies have experienced a substantial increase in institutional ownership. Regulators have urged institutional investors to play an active role in corporate governance. Specifically, institutional investors are urged to take a more proactive and effective stewardship role in shaping, influencing, and advocating for the ESG agenda within the Malaysian capital market by the Malaysian Code of Governance for Institutional Investors 2022 (
Lamptey et al., 2023). This study echoes the call to explore the implications of the presence of institutional investors on the audit process of ESG-engaged firms.
Fourthly, this study mainly focuses on the Malaysian environment. As Malaysia is an emerging market, the evidence obtained may be generalized to other emerging economies, such as Indonesia, Thailand, and the Philippines, or other countries that share similar institutional structures. Future researchers can utilize the findings in this study to facilitate their search for new research avenues related to the field of ESG reporting.
The study is organized as follows:
Section 2 provides the review of the literature and hypotheses development.
Section 3 discusses the research methodology.
Section 4 describes the empirical results, while
Section 6 wraps up the study.
6. Conclusions
6.1. Summary of Findings
This research examines the relationship between the ESG disclosure performance and audit fees in the Malaysian market, as well as the moderating effect of institutional ownership on this relationship. With the analysis of 323 firm-year observations from the years 2012 to 2020, using the panel data methodology, our study confirms (1) the existence of a positive association between ESG disclosure performance and audit fees, implying that ESG initiatives increase the audit effort; hence, there are higher audit fees, (2) institutional ownership strengthens the positive relationship between ESG performance and audit fees, suggesting that the presence of institutional shareholder demand for quality audits raises the audit fees.
6.2. Theoretical and Practical Implications
This paper offers theoretical and practical implications for multiple stakeholders. For researchers, this study identifies institutional ownership as a critical moderating factor that enhances the association between ESG and audit fees, closing the gap of previous studies. Since Malaysia is an emerging market, the findings could be extended to other developing nations with comparable institutional frameworks, like Indonesia, Thailand, and the Philippines. This study advances the ESG reporting literature by suggesting an additional research avenue for future researchers.
For regulators (including Bursa Malaysia and the Securities Commission), although disclosure mandates enhance transparency, they also add to the costs of compliance, particularly through the increased costs of audits. As such, regulators should consider coming up with additional and specific guidance on ESG verification processes that would help to mitigate these costs.
For companies, the study highlights the cost burden of ESG disclosure, particularly in contexts with high institutional ownership. Firms must recognize such costs as credibility investments rather than simply compliance costs.
For investors, the results show that ownership by institutions acts as a governance tool that improves the credibility of the reporting and thus should be included in the investment decision.
For auditors, this study provides a realistic, evidence-based approach to include ESG disclosure into risk assessments and audit fees. The positive association discovered shows that comprehensive ESG disclosures signify a need for increased auditing work, justifying a fee premium.
6.3. Limitations and Future Research Directions
This study has some limitations that need to be addressed by future research. First, our measure of ESG disclosure performance relies on the Bloomberg score, which, although detailed, may miss some aspects of reporting quality. Subsequent research could implement detailed content analytics on sustainability reports.
Second, this study treats institutional investors as a single group, whereas various kinds of institutional investors (for example, pressure-sensitive and pressure-resistant, domestic and foreign) may define different levels of monitoring intensity. Subsequent research should investigate how these types of investors impact the ESG–audit fee relationship.
Third, given its emerging economy status, Malaysia possesses its own unique characteristics. A cross-country analysis among different emerging markets would enhance the generalization of the findings.
Finally, as Malaysia started to implement the IFRS Sustainability Disclosure Standards on a mandatory basis in 2025, future research could focus on how the regulatory change affects the ESG disclosure–audit fee relationship.
