On September 9, 2025, the Greenhouse Gas Protocol (GHG Protocol) and International Organization for Standardization (ISO) announced a new strategic partnership to harmonize and co‑develop greenhouse gas (GHG) accounting standards. This announcement raises the stakes for the GHG Protocol's ongoing update process, which promises significant changes to its existing suite of corporate standards and guidance.

Key Takeaways

  • What's New: ISO and GHG Protocol will combine the ISO 1406x family with the GHG Protocol Corporate, Scope 2, and Scope 3 Standards into harmonized, dual-logo standards and will co-develop a new PCF standard.
  • Why it Matters: A single, interoperable framework should reduce duplicative work and conflicting terminology, making it easier for companies, auditors, and policymakers to compare emissions data.
