ISSB moves forward on targeted GHG disclosure amendments

On 25 September 2025, the ISSB advanced its work on targeted amendments to IFRS S2 Climate-related disclosures, aiming to address practical challenges in reporting greenhouse gas (GHG) emissions

These amendments include several key changes designed to clarify requirements and increase flexibility for reporting entities, such as: 

  • relief confirmed for disclosing Scope 3 Category 15 emissions beyond financed emissions; 
  • retention of the Global Industry Classification Standard (GICS) for disaggregating financed emissions, with a more flexible approach allowing entities to select a relevant classification system and justify their choice; 
  • extension of jurisdictional relief from using the Greenhouse Gas Protocol (GHG Protocol) and the applicability of that relief for the use of Global warming potential (GWP). 

Regarding the due process, all 12 ISSB members present unanimously confirmed that no further public consultation would be required. The amendments are therefore expected to be published by the end of 2025, with an effective date of 1 January 2027.
