The International Financial Reporting Standards Foundation has made available a Jurisdictional Readiness Assessment Guide and associated tool to help jurisdictions evaluate how prepared their markets are to adopt or otherwise use International Sustainability Standards Board (ISSB) Standards. The materials are intended to support evidence-based decisions on the pace, scope and sequencing of regulatory actions and to help identify capacity-building priorities. The readiness review framework covers the reporting ecosystem, reporting entities and the broader support system, and includes practical examples from the experiences of nearly 40 jurisdictions that have already taken steps to adopt or use ISSB Standards. It also draws on insights from 19 jurisdictions where requirements are already in effect. The guide and tool sit within the IFRS Foundation’s Regulatory Implementation Programme toolkit, alongside resources to help jurisdictions consider approaches, rationales and timelines for using ISSB Standards. The release coincides with regulators convening for the first meeting of the IFRS Foundation’s Jurisdictional Adopters Working Group, which is intended to facilitate multilateral discussion of ISSB Standards use and address cross-border considerations to mitigate fragmentation in regulatory reporting.
