In today’s global market, companies face increasing pressure to align with diverse sustainability reporting frameworks such as IFRS Sustainability Disclosure Standards, GRI, and ESRS. This guide provides an in-depth look at how businesses can navigate these complex requirements, ensuring transparency and consistency across different jurisdictions.
We will first provide an overview of the key information related to the ISSB S1/S2, GRI, and ESRS standards. We will then describe the approach followed to map the relevant disclosure parts from the underlying digital taxonomies that reflect these standards, presenting them in the form of tagged inline XBRL reports. This work will serve as the foundation for a future proof-of-concept mechanism that will enable companies, investors, and analysts to remap the machine-readable parts of sustainability reports to a variety of ESG standards.
