International Sustainability Standards Board (ISSB)

Understanding sustainability reporting can be challenging because different frameworks serve different purposes. The International Sustainability Standards Board, or ISSB, provides a globally consistent, investor-focused approach to sustainability disclosures. ISSB offers a clear example of how sustainability reporting is evolving to meet the needs of capital markets while remaining comparable across industries and countries.

What is ISSB

The ISSB was established in 2021 by the IFRS Foundation to create a global baseline for sustainability reporting. Its goal is to harmonize ESG disclosures, ensuring comparability, reliability, and integration with financial reporting, helping investors and stakeholders understand how environmental, social, and governance factors may affect enterprise value, and assess long-term value and climate-related risks.

The ISSB creates comprehensive sustainability disclosure standards with a focus on financial materiality. It builds on existing frameworks, including TCFD recommendations, and aims to provide a unified global baseline for reporting sustainability-related information.

Investor-focused approach

A distinguishing feature of ISSB is its emphasis on investor decision-making. The standards guide companies to report sustainability information that is relevant for assessing risks, opportunities, and long-term performance.

This approach encourages organisations to focus on issues that are financially material rather than reporting all sustainability topics indiscriminately. As a result, ISSB helps improve transparency and comparability in sustainability reporting across markets.

Core standards and structure

ISSB standards provide guidance on governance, strategy, risk management, and metrics and targets, often aligned with TCFD principles. Implementing ISSB standards involves identifying financially material sustainability topics, collecting accurate data, and presenting disclosures in line with the framework’s guidance.

Organisations may integrate ISSB reporting with other frameworks like GRI or SASB to satisfy different stakeholders’ needs while keeping investor-focused disclosures clear. Digital tools and data management systems support consistency, transparency, and comparability across reporting periods.
