ISO and GHG Protocol Announce Strategic Partnership for Unified GHG Emission Standards

【ISO-GHG Protocol Strategic Partnership】 The International Organization for Standardization (ISO) and the GHG Protocol announced on September 9, 2025, a partnership to harmonize existing GHG standards portfolio and jointly develop new standards for GHG emission calculation and reporting. The GHG Protocol is a joint initiative of the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD). 【Standards Integration Content】 They will integrate major GHG standards to develop harmonized, co-branded international standards. This includes ISO 1406X series on GHG along with GHG Protocol corporate accounting and reporting, Scope 2 (indirect emissions from electricity, heat, and steam supplied by other companies), and Scope 3 (indirect emissions other than Scope 2) standards. 【Product Carbon Footprint Standards】 Recognizing the need for consistent approaches across carbon accounting activities, both organizations will collaborate on developing product carbon footprint standards as decision-making guidance for decarbonization, reflecting growing corporate demand for access to more detailed data across entire value chains. 【Integration Effects and Outlook】 The integration of ISO 1406X series and GHG Protocol standards brings together technical rigor, policy relevance, and practicality in one standard. Both organizations will leverage their respective influence and credibility to accelerate global adoption and promote substantial emission reductions. ISO standards are used in government legislation and regulation, while GHG Protocol standards are utilized in major sustainability and information disclosure initiatives.
