IFRS S1 & S2: Transforming the Landscape of Sustainability Reporting


The International Financial Reporting Standards (IFRS) have long been the bedrock for consistent and transparent financial reporting globally. However, the landscape is evolving, and on June 26, 2023, the International Sustainability Standards Board (ISSB), an initiative of the IFRS Foundation, introduced two groundbreaking standards – IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures. These standards mark a significant leap towards harmonising sustainability reporting globally, influencing how companies divulge their environmental, social, and governance (ESG) performance.

The modern business landscape demands a comprehensive approach to reporting that extends beyond financial metrics. The ISSB’s introduction of IFRS S1 and S2 signifies a strategic move towards integrating sustainability factors into mainstream financial reporting, emphasising the need for businesses to address environmental and social impacts alongside financial performance.

The Birth of ISSB: Paving the Way for Global Sustainability Reporting Consistency

The ISSB, launched at COP26, aims to elevate the consistency and quality of sustainability reporting by aligning it with financial reporting regulations. Operating alongside the International Accounting Standards Board (IASB), the ISSB amalgamates the Climate Disclosure Standards Board (CDSB) and the Value Reporting Foundation (VRF), known for the Integrated Reporting Framework and the Sustainability Accounting Standards Board (SASB) Standards. This cohesive approach underscores the increasing importance of sustainability reporting in the business world.

The collaboration between CDSB and VRF within the ISSB creates a holistic platform for reporting that addresses both financial and sustainability dimensions. This union signifies a collective effort to provide businesses with a standardized framework, promoting not only transparency but also accountability in disclosing ESG-related information to stakeholders.

IFRS S1 outlines the general prerequisites for disclosing sustainability-related financial information. This encompasses details about a company’s sustainability risks and opportunities, governance of sustainability matters, and overall sustainability performance. Aligned with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), IFRS S1 lays the foundation for a standardised approach to sustainability reporting.

Companies adopting IFRS S1 gain a structured framework to communicate their commitment to sustainability. The standard necessitates a comprehensive disclosure of sustainability risks, pushing organisations to assess and address their environmental and social impact. By providing specific guidelines on governance practices related to sustainability, IFRS S1 encourages businesses to embed responsible practices within their corporate DNA.

In addition to addressing risks and opportunities, IFRS S1 prompts companies to delve deeper into their supply chain sustainability, urging a comprehensive examination of environmental and social impacts throughout the value chain. This broader scope ensures that companies not only manage their direct impact but also consider the implications of their entire business operations on sustainability.

Complementing IFRS S1, IFRS S2 focuses specifically on climate-related financial information. It delves into a company’s greenhouse gas emissions, climate-related risks and opportunities, and its strategy for addressing climate change. These specifications are vital not only for meeting regulatory requirements but also for empowering investors to make more informed decisions by considering a company’s climate resilience.

The introduction of IFRS S2 represents a major stride towards integrating climate considerations into financial decision-making. By mandating the disclosure of climate-related risks and opportunities, the standard equips investors with critical information to assess a company’s preparedness for climate change. This not only serves the interests of investors but also aligns businesses with global efforts to mitigate climate impacts.

IFRS S2 prompts companies to go beyond the quantitative aspects of greenhouse gas emissions by emphasising the qualitative aspects. This involves disclosing the measures taken to mitigate emissions and demonstrating a commitment to proactive climate action rather than mere compliance. The standard encourages a narrative that goes beyond numbers, underlining the strategic thinking behind a company’s approach to climate-related challenges.

Effective Implementation and Transition

The standards are effective for annual reporting periods beginning on or after January 1, 2024, with early application permitted, provided IFRS S2 is also applied simultaneously. This allows companies to proactively adopt these standards and align their sustainability reporting with the evolving global landscape.

The transition to IFRS S1 and S2 signifies a strategic move towards a future where sustainability reporting is as integral as financial reporting. Early adopters have the advantage of showcasing their commitment to sustainable practices, positioning themselves as leaders in a business environment increasingly shaped by ESG considerations.

Benefits of Implementing IFRS S1/S2:

1. Improved Transparency and Consistency

IFRS S1 and S2 pave the way for more transparent and consistent sustainability reporting, facilitating easier comparisons between companies.

By enhancing transparency, businesses adopting IFRS S1 and S2 contribute to building trust among stakeholders. Standardised reporting allows for a clearer understanding of each company’s sustainability journey, enabling investors and other stakeholders to make more informed decisions.

2. Enhanced Investor Decision-Making

Investors gain access to crucial information, empowering them to make informed decisions that align with sustainable practices.

Incorporating sustainability metrics in financial reporting assists investors in aligning their portfolios with their ESG goals. This integration ensures that investment decisions reflect not only financial performance but also a commitment to sustainable and responsible business practices.

3. Reduced Costs

Designed for efficiency, IFRS S1 and S2 offer a cost-effective solution, allowing companies to meet sustainability reporting requirements across multiple jurisdictions.

The efficiency of IFRS S1 and S2 lies in their ability to streamline sustainability reporting, minimising the burden on companies. The cost-effectiveness of these standards ensures that businesses can meet their sustainability reporting obligations without excessive financial strain.

Challenges and Considerations in Implementing IFRS S1/S2

1. Data Collection and Management:

Companies may face challenges in collecting and managing extensive sustainability-related financial information, necessitating robust systems and processes.

Businesses may need to realign their reporting structures to seamlessly integrate IFRS S1 and S2 with existing financial reporting frameworks. This adaptation necessitates careful consideration of reporting workflows to avoid redundancy and ensure a cohesive disclosure strategy.

3. Training and Skill Development:

Employees may require training to understand and implement the new reporting requirements, emphasising the need for skill development in sustainability reporting.

As companies transition to IFRS S1 and S2, investing in training programs becomes crucial. Employees need to develop the skills required to navigate the complexities of sustainability reporting, ensuring accurate and effective compliance with the new standards.


In conclusion, the introduction of IFRS S1 and S2 by the ISSB marks a pivotal moment in the evolution of sustainability reporting. These standards not only provide a framework for transparent and consistent reporting but also empower investors to make decisions that promote sustainable practices. As we move towards a future where ESG considerations are integral to financial decision-making, these standards become a cornerstone for businesses committed to environmental and social responsibility.

The adoption of IFRS S1 and S2 is not merely a compliance measure; it represents a strategic shift towards a business paradigm that values environmental and social sustainability as key drivers of success. Companies embracing these standards signal financial stability and a commitment to addressing the challenges of our time, making sustainability an integral part of their corporate ethos.
