The ISSB is an independent, global body responsible for developing and publishing environmental, social, and governance (ESG) disclosure standards. The ISSB's mission is to create a comprehensive set of standards that helps companies provide investors and other stakeholders with consistent, comparable, and reliable sustainability information.
Established in 2021, the ISSB was created in response to investors looking for reliable ESG information from companies. The ISSB standards simplify this process by standardizing disclosure to help investors more effectively compare and analyze ESG performance across companies. The ISSB also serves to harmonize and merge previously disparate frameworks to simplify the reporting process.
The ISSB was established by the International Financial Reporting Standards (IFRS) Foundation, which also oversees the International Accounting Standards Board (IASB). This ensures that ISSB standards are aligned with existing financial reporting frameworks and that sustainability reporting is integrated into mainstream financial reporting.
It’s estimated the ISSB standards may affect 100,000 to 130,000 companies worldwide. This is largely due to the International Organization of Securities Commissions (IOSCO), which is considered the global standard setter for securities regulation, endorsing the ISSB standards in 2023. Companies may choose to adopt the standards voluntarily in response to stakeholder pressure and growing demand for transparency. Some countries, such as Australia, Brazil, Canada, Japan, Mexico, Singapore, and the UK, have also mandated or are developing ISSB-based regulations.
While exact rules for compliance vary based on jurisdiction, company size, and other factors, impacted businesses are expected to report as early as 2025. In general, the companies in scope are publicly traded — but in some countries, they also apply to larger private companies.
In June 2023, the ISSB published its inaugural standards, IFRS S1 and S2:
IFRS S1 and S2 simplify the evaluation of a company's sustainability and climate-related practices, enabling investors with more informed decision-making.
IFRS S1 outlines the general requirements for a complete set of sustainability-related financial disclosures, including all risks and opportunities that could affect the entity’s cash flows, access to finance, or cost of capital.
IFRS S2 is a topic-based standard that specifies disclosures relating to climate, including all risks and opportunities that could affect the entity’s prospects.
These standards are designed to be applied in conjunction with IFRS S2 building on IFRS S1. Both standards require disclosures about governance, strategy, risk management, and metrics and targets.
In time, the ISSB is planning to release other topic-based standards, eventually establishing specific guidelines for many ESG-related topics.

The ISSB relates to and expands on many other global sustainability reporting frameworks, including (but not limited to):
The TCFD is a framework that helps organizations disclose information about climate change, but was disbanded following the ISSB’s release of IFRS S1 and S2. While the TCFD is still available for use, companies are encouraged to instead use IFRS S2 as the new baseline for climate-related disclosures.
The CDSB and VRF formally consolidated under ISSB and no longer exist independently.
CDP and ISSB collaborate to more closely align CDP’s climate questionnaire with IFRS S2.
