The International Organization for Standardization (ISO) and the Greenhouse Gas (GHG) Protocol have announced a strategic partnership to harmonize and co-develop global standards for greenhouse gas emissions accounting and reporting. Under this agreement, they will integrate their respective existing standards, such as ISO’s 1406X series and the GHG Protocol’s Corporate, Scope 2, and Scope 3 standards, into a unified, co-branded portfolio. They also plan to jointly create a product carbon footprint standard to better track emissions across supply chains.

This collaboration aims to reduce fragmentation in carbon accounting, simplify reporting for organizations, strengthen consistency across jurisdictions, and support more credible, science-based decarbonization efforts. With a shared “global language” for emissions data, the partnership is intended to bolster trust among companies, policymakers, verifiers, auditors, and investors – helping accelerate climate action worldwide.
