Suite of Corporate Standards: Quarter 3 2025 Technical Working Groups Update    

GHG Protocol currently has five Technical Working Groups in process. Below is a high-level update about what each workstream has been working on between July and September 2025. You can view the materials from Technical Working Group meetings in GHG Protocol’s Standards Development and Governance Repository.      

• Corporate Standard Technical Working Group: The TWG has begun discussions on phase 2 topics including base year recalculation (Subgroup 1) and data quality (Subgroup 3) and has continued to make progress on the phase 1 topic of consolidation approaches (Subgroup 2). Preliminary phase 1 outcomes agreed upon by the TWG were presented to the Independent Standards Board (ISB) in July, with ISB decisions planned for this fall.
• Scope 2 Technical Working Group: The TWG’s proposal to update the location- and market-based methods was approved by the Independent Standards Board (ISB) to proceed to public consultation this fall (10–1 votes in both cases). The 60-day consultation will gather feedback on draft updates, including updated emission factor hierarchies and hourly and regional matching criteria, with feasibility measures including load profiles for hourly matching, exemption thresholds for smaller organizations, a legacy clause for existing contracts, and an anticipated phased implementation period before adoption of the revised standard. In parallel, the ISB directed electricity sector avoided emissions concepts to advance under the cross-sector Actions & Market Instruments workstream.
• Scope 3 Technical Working Group: The TWG completed phase 1 revisions across its three subgroups and presented them to the ISB for review in July, with ISB decisions planned for this fall. The Scope 3 TWG began work on phase 2 topics, beginning with boundary setting updates for each of the individual scope 3 categories.
• Actions and Market Instruments Technical Working Group: The AMI TWG is currently producing a Phase 1 White Paper, which provides key concepts, principles, and approaches for multi-statement reporting of actions and market instruments in a comprehensive and transparent GHG report. The TWG will meet in an in-person workshop this fall to accelerate progress, then submit TWG recommendations to the ISB in December. If agreed by the ISB, the white paper is intended to be published by the end of the year, summarizing key deliverables of AMI Phase 1 work.  
• Forest Carbon Accounting Technical Working Group: The TWG has concluded its work developing forest carbon accounting proposals for the ISB. The ISB is still discussing the tradeoffs between the different forest carbon accounting proposals.
