ISSB (International Sustainability Standards Board

1. International Sustainability Standards Board (ISSB)

The International Sustainability Standards Board (ISSB) is a pivotal body in the evolving landscape of corporate reporting, aiming to establish globally consistent, comparable, and reliable sustainability-related financial disclosures. This article provides a comprehensive overview of the ISSB, its formation, objectives, standards, implementation challenges, and its relationship to other sustainability reporting frameworks. It is aimed at beginners with limited prior knowledge of the subject.

Background and Formation

For years, the lack of standardized sustainability reporting posed a significant challenge for investors, companies, and other stakeholders. A fragmented ecosystem of frameworks – such as the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), Task Force on Climate-related Financial Disclosures (TCFD), and others – resulted in inconsistent data, making comparisons difficult and hindering informed decision-making. Investors increasingly demanded sustainability information, not as a separate "nice-to-have," but as integral to understanding a company’s financial performance and long-term value creation. This demand, coupled with growing regulatory pressure, spurred the creation of a unified global standard.

The ISSB was formally established in November 2021 by the IFRS Foundation, the organization responsible for the International Financial Reporting Standards (IFRS). The IFRS Foundation recognized the need for a dedicated board to develop sustainability-related disclosure standards that are specifically designed to deliver value to global capital markets. The creation of the ISSB was a direct response to requests from the G20 and other global bodies for a consolidated and standardized approach to sustainability reporting. It effectively consolidated the work of the Value Reporting Foundation (VRF), which previously housed both SASB and the TCFD, bringing these crucial elements under a single umbrella.

Objectives of the ISSB

The ISSB’s core objective is to develop a comprehensive set of sustainability-related disclosure standards that meet the information needs of investors. These standards are designed to:

• **Enhance comparability:** By establishing a common language and set of metrics, the ISSB standards enable investors to compare the sustainability performance of different companies, even across industries and geographies.
• **Improve reliability:** The standards aim to ensure that sustainability information is accurate, verifiable, and subject to appropriate levels of assurance.
• **Increase efficiency:** Standardized reporting reduces the burden on companies to respond to multiple reporting requests from different stakeholders.
• **Support capital allocation:** By providing investors with high-quality, decision-useful sustainability information, the ISSB standards facilitate more informed capital allocation decisions.
• **Drive sustainable practices:** Increased transparency and accountability incentivizes companies to improve their sustainability performance.

The ISSB’s focus is primarily on information that is financially material – meaning information that could reasonably be expected to influence the economic decisions of investors. This differentiates it from broader sustainability reporting frameworks like GRI, which cover a wider range of environmental, social, and governance (ESG) topics, including those that may not be directly financially material. However, the ISSB recognizes the interconnectedness between financial and non-financial performance and aims to build upon the work of existing frameworks, rather than replace them entirely.

The ISSB Standards: IFRS Sustainability Disclosure Standards

The ISSB develops standards known as IFRS Sustainability Disclosure Standards. As of late 2023/early 2024, the key standards are:

• **IFRS S1 – General Requirements for Disclosure of Sustainability-related Financial Information:** This standard establishes the overarching requirements for sustainability-related disclosures. It mandates that companies disclose their significant sustainability-related risks and opportunities, how these impact their financial statements, and the processes they use to identify, assess, and manage these risks and opportunities. It requires disclosures on governance, strategy, risk management, and metrics and targets. The four core elements of IFRS S1 are: Governance, Strategy, Risk Management, and Metrics & Targets. This is the foundational standard.
• **IFRS S2 – Climate-related Disclosures:** This standard focuses specifically on climate-related risks and opportunities. It builds upon the recommendations of the TCFD and provides a more detailed framework for disclosing climate-related financial information. It covers both physical risks (e.g., extreme weather events) and transition risks (e.g., changes in policy or technology). The standard requires companies to disclose their Scope 1, Scope 2, and Scope 3 greenhouse gas emissions. This standard allows for a phased implementation, recognizing the challenges associated with Scope 3 emissions reporting.

The ISSB is actively working on future standards. Areas under consideration include biodiversity and ecosystems, human capital, and water. These standards will likely follow a similar structure to S1 and S2, focusing on financially material information. The ISSB aims to deliver a complete suite of disclosure standards covering all key sustainability topics over the coming years.

Key Concepts and Definitions

Understanding the ISSB's terminology is crucial. Some key concepts include:

• **Sustainability-related risks and opportunities:** Events or conditions that could affect a company’s financial performance, future cash flows, or access to capital due to sustainability factors.
• **Materiality:** The threshold at which information is considered important enough to influence the decisions of investors. The ISSB emphasizes *financial* materiality.
• **Value Chain:** The full range of activities, resources, and relationships involved in creating and delivering a company’s products or services. This is particularly important for Scope 3 emissions reporting.
• **Governance:** The processes and structures through which a company is directed and controlled.
• **Transition Risks:** Risks associated with the shift to a lower-carbon economy, such as changes in regulation, technology, and consumer preferences.
• **Physical Risks:** Risks arising from the physical effects of climate change, such as extreme weather events and sea-level rise.
• **Scope 1 Emissions:** Direct greenhouse gas emissions from sources owned or controlled by the reporting company.
• **Scope 2 Emissions:** Indirect greenhouse gas emissions from the generation of purchased electricity, steam, heat, or cooling consumed by the reporting company.
• **Scope 3 Emissions:** All other indirect emissions that occur in a company’s value chain, both upstream and downstream.

Implementation Challenges and Timelines

Implementing the ISSB standards presents several challenges for companies:

• **Data availability and quality:** Gathering accurate and reliable sustainability data can be complex and resource-intensive, particularly for Scope 3 emissions. [1](McKinsey on Scope 3) provides detailed analysis.
• **Integration with financial reporting:** Integrating sustainability information into existing financial reporting processes requires significant changes to systems and controls.
• **Assurance:** Obtaining independent assurance of sustainability disclosures is crucial for building trust, but the market for sustainability assurance is still developing. [2](EY Sustainability Assurance) offers insights.
• **Capacity building:** Companies need to invest in training and development to ensure that their staff have the skills and knowledge to implement the standards effectively.
• **Cost:** Implementation can be costly, especially for smaller companies.

The ISSB is encouraging early adoption of the standards. Many jurisdictions are considering mandating ISSB-aligned reporting. The timelines for mandatory adoption vary:

• **EU:** The European Union is integrating ISSB standards into its Corporate Sustainability Reporting Directive (CSRD). [3](ESMA CSRD)
• **Canada:** Canada has indicated its intention to mandate ISSB-aligned reporting.
• **United States:** The SEC (Securities and Exchange Commission) is considering climate-related disclosure rules that are informed by the TCFD and ISSB standards. [4](SEC Climate Disclosure)
• **Other Jurisdictions:** Many other countries are actively evaluating the ISSB standards and considering their adoption.

Relationship to Other Frameworks

The ISSB standards are designed to work alongside, rather than replace, other sustainability reporting frameworks.

• **GRI:** While the ISSB focuses on financial materiality, the GRI provides a more comprehensive framework for reporting on a wider range of sustainability topics. Companies may choose to report using both frameworks, with the ISSB standards informing their financial disclosures and the GRI standards providing more detailed information on their broader sustainability performance.
• **SASB:** The SASB standards, which were previously housed within the VRF, provide industry-specific guidance on financially material sustainability topics. The ISSB standards build upon the SASB standards and incorporate many of their key concepts.
• **TCFD:** The ISSB’s Climate-related Disclosures standard (S2) is directly based on the recommendations of the TCFD.
• **CDP:** CDP (formerly the Carbon Disclosure Project) is a global disclosure system for environmental data. Companies may continue to report to CDP in addition to complying with the ISSB standards. [5](CDP website)
• **Integrated Reporting (<IR>):** The ISSB standards align with the principles of Integrated Reporting, which emphasizes the interconnectedness between financial and non-financial performance. [6](Integrated Reporting website)

The Future of Sustainability Reporting

The ISSB represents a significant step forward in the evolution of sustainability reporting. The move towards global standardization is expected to improve the quality, comparability, and reliability of sustainability information, ultimately leading to more informed investment decisions and a more sustainable global economy. However, challenges remain, including the need to address data availability, assurance, and the evolving landscape of sustainability risks and opportunities. Ongoing collaboration between the ISSB, regulators, companies, and other stakeholders will be essential to ensure the continued success of this important initiative.
