Introduction To ESG Reporting Requirements
ESG reporting requirements are the laws, regulations, and standards that mandate organizations to disclose information about their environmental, social, and governance performance. These requirements have grown significantly in recent years, driven by increasing stakeholder demand for transparency, growing recognition of the financial materiality of ESG factors, and regulatory developments around the world. ESG reporting requirements are designed to ensure that organizations provide consistent, comparable, and reliable information to stakeholders, enabling them to make informed decisions. Understanding ESG reporting requirements is essential for leaders who want to build organizations that are transparent, accountable, and trusted by their stakeholders.
The importance of ESG reporting requirements cannot be overstated. Stakeholders, including investors, customers, employees, and regulators, are increasingly demanding information about organizations’ ESG performance. ESG reporting provides the information needed to assess risks and opportunities, to make investment decisions, and to hold organizations accountable. Organizations that fail to meet ESG reporting requirements risk reputational damage, loss of investor confidence, and regulatory penalties.
ESG reporting requirements are not static. They are evolving rapidly as new regulations are introduced and as existing standards are updated. Organizations must stay current with these developments and must ensure that their reporting practices are compliant with all applicable requirements.
ESG reporting requirements are a multidisciplinary field that draws on accounting, law, and sustainability. They are a critical component of stakeholder engagement and should be integrated into the organization’s overall reporting and governance processes.
The Purpose Of ESG Reporting Requirements
ESG reporting requirements serve several important purposes.
Ensuring Transparency: ESG reporting requirements ensure that organizations are transparent about their ESG performance. Transparency builds trust and enables stakeholders to make informed decisions.
Providing Comparable Information: ESG reporting requirements ensure that organizations provide consistent and comparable information. Comparability enables stakeholders to assess and compare performance across organizations.
Informing Decision-Making: ESG reporting requirements provide information that informs decision-making. Investors, customers, and other stakeholders use ESG information to make decisions.
Promoting Accountability: ESG reporting requirements promote accountability. By requiring organizations to disclose their ESG performance, they enable stakeholders to hold organizations accountable.
Identifying Risks And Opportunities: ESG reporting requirements help organizations to identify risks and opportunities. By disclosing ESG information, organizations can identify areas for improvement.
Driving Improvement: ESG reporting requirements drive improvement. By requiring organizations to measure and disclose their ESG performance, they incentivize improvement.
Meeting Stakeholder Expectations: ESG reporting requirements help organizations to meet stakeholder expectations. By providing ESG information, organizations can demonstrate their commitment to responsible business practices.
Key ESG Reporting Frameworks And Standards
Several key frameworks and standards provide guidance for ESG reporting.
The Global Reporting Initiative
The Global Reporting Initiative Standards are the most widely used sustainability reporting standards in the world. The GRI Standards provide a framework for organizations to report on their economic, environmental, and social impacts.
Global Reach: The GRI Standards are used by 40 percent of all large listed companies, representing 62 percent of global market capitalization. GRI’s reach is genuinely global, used by companies headquartered in 107 jurisdictions worldwide, including 71 percent of market cap for the Global South.
Multi-Framework Practice: Sustainability reporting is a multi-framework practice. Companies using ISSB Standards and ESRS also reference GRI. This demonstrates that GRI is a foundational standard for many organizations.
Impact Materiality: The GRI Standards emphasize impact materiality, focusing on the organization’s impacts on the environment and society. This is a key distinction from frameworks that focus primarily on financial materiality.
Adoption Rates: GRI reporting rates are led by jurisdictions in Asia and Latin America, with the highest levels including Taiwan (China) at 95 percent of companies, Argentina at 82 percent, Colombia at 79 percent, Singapore at 76 percent, Brazil at 71 percent, and Malaysia at 70 percent.
The International Sustainability Standards Board
The ISSB has developed the IFRS Sustainability Disclosure Standards, which provide a global baseline for sustainability reporting. The ISSB standards focus on financial materiality, providing information that is useful to investors.
IFRS S1 and S2: The ISSB has issued two primary standards: IFRS S1, which provides general requirements for disclosure of sustainability-related financial information, and IFRS S2, which provides climate-related disclosures.
Amendments: In December 2025, the ISSB issued Amendments to Greenhouse Gas Emissions Disclosures, which amended IFRS S2. The amendments are effective for annual reporting periods beginning on or after 1 January 2027, with early application permitted.
Effective Date: The revised content is effective from 1 January 2027, with early application permitted.
Adoption: Globally, 582 companies use IFRS S1 and S2 from the ISSB.
The European Sustainability Reporting Standards
The European Sustainability Reporting Standards are the detailed technical standards that specify what in-scope companies must disclose under the Corporate Sustainability Reporting Directive. The ESRS apply the principle of double materiality, requiring disclosure of both financial materiality and impact materiality.
Structure: ESRS contains 2 cross-cutting standards and 10 topical standards. The standards cover general, environmental, social, and governance topics.
Revised Standards: In 2026, the ESRS were revised to shorten and clarify the text of the standards. Mandatory requirements have been moved to the main body of each standard. Application requirements have been reduced and relocated into the body of each standard.
Key Changes: The revised ESRS include updated thresholds for determining if there is significant employment in a country: countries that have 50 or more employees by head count and that are among the countries with the 10 highest number of employees. For the disclosure of incidents of discrimination, only substantiated and verified incidents are required to be reported.
Effective Date: ESRS is required to be applied for financial years beginning on or after 1 January 2027.
The Corporate Sustainability Reporting Directive
The Corporate Sustainability Reporting Directive is a European Union directive that requires companies to report on sustainability matters. The CSRD expands the scope of sustainability reporting to include a much larger number of companies.
Scope: The CSRD applies to all large companies and listed SMEs operating in the EU. It significantly expands the number of companies required to report on sustainability matters.
Double Materiality: The CSRD applies the principle of double materiality, requiring disclosure of both financial materiality and impact materiality. This means companies must report on how sustainability issues affect the company and how the company affects society and the environment.
Reporting Standards: The CSRD requires companies to report in accordance with the European Sustainability Reporting Standards.
Assurance: The CSRD requires limited assurance on sustainability reporting, with a transition to reasonable assurance over time.
The Task Force On Climate-Related Financial Disclosures
The TCFD recommendations provide a framework for companies to disclose climate-related financial risks and opportunities. The TCFD framework is organized around four pillars: governance, strategy, risk management, and metrics and targets.
Governance: The governance pillar focuses on the organization’s governance of climate-related risks and opportunities.
Strategy: The strategy pillar focuses on the impact of climate-related risks and opportunities on the organization’s strategy and financial planning.
Risk Management: The risk management pillar focuses on the organization’s processes for identifying, assessing, and managing climate-related risks.
Metrics And Targets: The metrics and targets pillar focuses on the metrics and targets that the organization uses to assess and manage climate-related risks and opportunities.
Integration: The TCFD recommendations have been integrated into the ISSB standards, and the ISSB has taken over responsibility for climate-related disclosures.
The Sustainability Accounting Standards Board
The SASB Standards are industry-specific standards for sustainability reporting. The SASB Standards focus on financial materiality, providing information that is useful to investors.
Industry-Specific: The SASB Standards are organized by industry, with each industry having its own set of standards. The industry-specific approach ensures that companies disclose information that is material to their financial performance.
Financial Materiality: The SASB Standards are based on the concept of financial materiality, focusing on sustainability issues that are most likely to affect the financial performance of companies in each industry.
Investor Focus: The SASB Standards are designed to be used by companies to disclose information to investors. The standards are focused on providing decision-useful information that is relevant to investors’ investment decisions.
Integration: The SASB Standards have been integrated into the ISSB standards, and the ISSB has taken over responsibility for industry-specific standards.
