The Role and Impact of the International Sustainability Standards Board (ISSB)

A Catalyst for Clarity: Introduction to the ISSB

At the UN Climate Change Conference (COP26) in November 2021, the establishment of the International Sustainability Standards Board (ISSB) marked a pivotal moment for global sustainability reporting. The ISSB was conceived as a response to the pressing need for standardized sustainability reporting, recognizing the demands from investors and stakeholders for clear and internationally consistent metrics to evaluate companies’ environmental, social, and governance (ESG) performance.

As per the ISSB’s mission, it aims to create a unified approach to sustainability reporting, streamlining the complex web of existing frameworks. This endeavour not only alleviates the burdens of compliance but also fosters greater uptake by businesses. Sir Ronald Cohen, the pioneering advocate of impact investing, aptly encapsulates the ISSB’s vision: “By creating global standards for sustainable investing, the ISSB will play a vital role in addressing the urgent challenges of our time.”

The ISSB’s Fundamental Objectives

The International Sustainability Standards Board is geared towards aligning sustainability reporting with capital market requirements, thereby enabling investors to make well-informed decisions. The ISSB acknowledges that the plethora of existing sustainability frameworks has led to fragmented and inconsistent reporting practices, obstructing meaningful comparisons across industries and regions. Its primary objective is to bridge this information gap, enhancing the reliability, usefulness, and comparability of sustainability disclosures.

The ISSB’s strategic approach involves collaboration with stakeholders from various sectors, including government bodies and corporations. By leveraging the expertise of existing disclosure frameworks, the ISSB aims to design a global baseline that addresses the multifaceted challenges posed by sustainability reporting. In the words of Mary Schapiro, Vice Chair of the TCFD, “The ISSB’s efforts will usher in a new era of financial disclosures that integrate climate and sustainability, strengthening the resilience of financial markets.”

IFRS Foundation’s Authority and Expertise

The ISSB derives its authority from the International Financial Reporting Standards (IFRS) Foundation, a seasoned player in the realm of financial reporting. The IFRS Foundation’s track record of over three decades in setting globally accepted accounting standards lends credibility to the ISSB’s mission. While the ISSB and the International Accounting Standards Board (IASB) have distinct goals, they share a common commitment to enhancing transparency and comparability in corporate reporting. The establishment of the ISSB signifies a paradigm shift, where financial statements alone no longer suffice to reflect a company’s sustainable value over time.

Unpacking the ISSB’s Scope

The ISSB’s recent milestones include the release of exposure drafts, and inviting stakeholder input on key sustainability reporting standards. These drafts encompass IFRS S1 (IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information (PDF)), General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 (IFRS S2 Climate-related Disclosures (PDF)) Climate-related Disclosures. The former proposes a universal structure for sustainability disclosures, drawing inspiration from sector-specific standards like the Sustainability Accounting Standards Board (SASB). The latter aligns with the recommendations of the Taskforce on Climate-related Financial Disclosures (TCFD), focusing on climate-related governance, strategy, risk management, metrics, and targets.

By amalgamating the SASB standards, IFRS S1 underscores the importance of industry-specific nuances in sustainability reporting. This acknowledgement reflects the ISSB’s commitment to accommodating the diversity of sustainability challenges faced by different sectors. As aptly stated by Christine Lagarde, President of the European Central Bank, “The ISSB’s integration of sectoral expertise ensures a tailored yet cohesive approach to sustainability disclosures.”

Incorporating Existing Standards: A Holistic Approach

The amalgamation of standards within the ISSB reflects its intention to create a comprehensive repository for organizations seeking guidance on sustainability reporting. The ISSB’s alignment with the Value Reporting Foundation, which houses the SASB and the Climate Disclosure Standards Board (CDSB), underscores its commitment to simplifying compliance. Leveraging sector-specific expertise and existing guidelines ensures that organizations can navigate the complex landscape of sustainability reporting with greater ease and accuracy.

As the ISSB evolves, it grapples with the incorporation of other sustainability standards such as the Global Reporting Initiative (GRI) and the European Sustainability Reporting Standards (ESRS). These frameworks emphasize a double materiality approach, transcending financial impacts to encompass societal and environmental effects. The ISSB’s collaborative approach reflects its dedication to harmonizing the diverse perspectives within the sustainability reporting ecosystem.

Towards a Coherent Future: Conclusion

The emergence of the International Sustainability Standards Board is a watershed moment in the evolution of sustainability reporting. By consolidating existing frameworks, embracing sector-specific expertise, and aligning with global initiatives, the ISSB is poised to usher in an era of standardized, transparent, and comparable sustainability disclosures. As organizations adapt to the changing landscape, the ISSB’s impact resonates far beyond the realm of financial markets—it is a beacon guiding companies towards sustainable practices that resonate with stakeholders and investors worldwide. In the words of Margaret Mead, “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has.” The ISSB stands as a testament to the power of collaboration in shaping a more sustainable future.
