Sustainability Reporting: The Growing Role of Accountants in ESG Disclosures

By Francine A. Laourou
Business Finances Accounting

In recent years, sustainability reporting has evolved from a peripheral concern to a central element of corporate accountability and transparency. Environmental, Social, and Governance (ESG) disclosures have become critical for investors, regulators, and other stakeholders seeking to evaluate a company’s long-term viability and ethical performance. Accountants, traditionally focused on financial reporting, are increasingly pivotal in ensuring the credibility, accuracy, and integration of ESG information within corporate disclosures. This article examines the expanding role of accountants in sustainability reporting, the challenges and frameworks involved, and the implications for the accounting profession.

The Emergence of ESG Reporting

Sustainability reporting encompasses the disclosure of non-financial information related to environmental stewardship, social responsibility, and governance practices. The rise of ESG reporting is driven by growing recognition that financial performance alone does not capture all risks and opportunities affecting corporate value (Eccles & Krzus, 2018). Climate change, social inequality, and governance failures have underscored the need for comprehensive disclosure frameworks that address these dimensions.

Investors increasingly incorporate ESG factors into their decision-making, motivated by evidence linking strong ESG performance to reduced risk and enhanced returns (Friede, Busch, & Bassen, 2015). Regulatory bodies worldwide are also mandating more rigorous ESG disclosures, exemplified by the European Union’s Corporate Sustainability Reporting Directive (CSRD) and the U.S. Securities and Exchange Commission’s (SEC) proposed climate disclosure rules (European Commission, 2021; SEC, 2022).

Accountants as Stewards of ESG Reporting Integrity

Accountants’ expertise in measurement, verification, and assurance positions them to play a central role in ESG reporting. The profession’s foundational principles—accuracy, consistency, and transparency—are essential for credible sustainability disclosures (IFAC, 2020).

  • Data Collection and Validation: Accountants help design and implement robust data collection systems to capture ESG metrics such as greenhouse gas emissions, labor practices, and board diversity. Ensuring data completeness and reliability is critical given the diverse and often qualitative nature of ESG information (KPMG, 2020).

  • Integration with Financial Reporting: Integrating ESG data with traditional financial reports enhances the holistic understanding of corporate performance. Accountants facilitate this integration by aligning ESG disclosures with financial statements and notes, supporting comprehensive stakeholder communication (Eccles & Krzus, 2018).

  • Assurance and Audit of ESG Information: Independent assurance of ESG reports is gaining prominence to enhance stakeholder confidence. Accountants, especially auditors, apply assurance methodologies adapted to non-financial data, verifying the accuracy and adherence to reporting standards (IAASB, 2019).

ESG Reporting Frameworks and Standards

The proliferation of ESG reporting frameworks presents both opportunities and challenges for accountants. Leading frameworks include:

  • Global Reporting Initiative (GRI): Focuses on stakeholder-centric sustainability reporting, emphasising transparency and disclosure of material ESG topics (GRI, 2021).

  • Sustainability Accounting Standards Board (SASB): Provides industry-specific standards to identify financially material ESG factors relevant to investors (SASB, 2018).

  • Task Force on Climate-related Financial Disclosures (TCFD): Recommends disclosures related to climate risks and opportunities, emphasising governance, strategy, risk management, and metrics (TCFD, 2017).

  • International Sustainability Standards Board (ISSB): Established to develop a global baseline of sustainability disclosure standards, aiming to harmonise ESG reporting (IFRS Foundation, 2022).

Accountants must navigate these frameworks, often selecting or combining standards to meet stakeholder expectations and regulatory requirements. This necessitates a deep understanding of ESG materiality, sector-specific risks, and reporting best practices (KPMG, 2020).

Challenges in ESG Reporting

Despite progress, ESG reporting faces significant challenges:

  • Data Quality and Comparability: ESG data often lacks standardisation, making comparisons across companies and industries difficult. Subjectivity in metrics and voluntary disclosure exacerbate inconsistencies (Eccles & Krzus, 2018).

  • Measurement Complexity: Quantifying social and governance factors presents methodological difficulties. For example, assessing corporate culture or human rights impacts requires qualitative judgment and proxy indicators (Friede et al., 2015).

  • Regulatory Uncertainty: Evolving regulations and fragmented global standards create compliance complexities. Organisations must remain agile to adapt to new disclosure mandates (European Commission, 2021).

Accountants contribute to overcoming these challenges by applying rigorous controls, advocating for standardised metrics, and engaging in policy development (IFAC, 2020).

Implications for the Accounting Profession

The expanding role in ESG reporting is reshaping the accounting profession:

  • Skill Development: Accountants require new competencies in sustainability concepts, data analytics, and assurance of non-financial information. Professional bodies are updating curricula and continuing education to address these needs (IFAC, 2020).

  • Advisory Services: Beyond assurance, accountants increasingly advise clients on ESG strategy, risk management, and reporting frameworks, elevating their role as strategic business partners (KPMG, 2020).

  • Ethical Considerations: Accountants must uphold ethical standards in ESG reporting, ensuring transparency and resisting pressures to misrepresent or greenwash sustainability performance (IAASB, 2019).

Conclusion

Sustainability reporting is no longer optional but a critical component of corporate accountability. Accountants are uniquely positioned to ensure the integrity, accuracy, and relevance of ESG disclosures, thereby supporting informed decision-making by investors and other stakeholders. As ESG frameworks evolve and regulatory demands increase, the profession must continue to adapt through skill enhancement and ethical vigilance. Ultimately, accountants will be central to advancing sustainable business practices and fostering long-term value creation.
