WASHINGTON DC (October 24, 2025) – Following the announcement of a strategic partnership between the International Organization for Standardization (ISO) and GHG Protocol to deliver unified global standards for greenhouse gas (GHG) emissions accounting in September, the two organizations are launching their first joint working group to develop a new product-level GHG accounting standard.

The standard will be developed under joint governance of ISO and GHG Protocol, with contributions from experts across both organizations. To enable this, ISO Working Group 8 (within Technical Committee 207/Subcommittee 7), will be expanded into a Joint Working Group (JWG) under agreed Terms of Reference. This structure ensures broad participation and technical depth from across the GHG accounting ecosystem.

Building on ISO 14067 and the existing GHG Protocol Product Life Cycle Accounting and Reporting Standard, the new standard will maintain continuity with existing frameworks while advancing toward a unified global methodology. The JWG will in particular seek to leverage and build on existing approaches and new ideas by initiatives in the ecosystem, with the objective of developing a standard which is truly fit-for-purpose in line with the changing needs of corporates, investors and regulators.

GHG Protocol is now calling for experts to join the JWG and help shape a best-in-class standard focused on facilitating practical application.

Background on the Partnership

A key deliverable of the ISO-GHG Protocol strategic partnership is the joint product-level standard that responds to growing demand for granular emissions data across value chains. It will support credible decarbonization strategies, enhance market transparency, and enable implementation of mechanisms such as Carbon Border Adjustment Mechanisms (CBAMs) through a harmonized methodology.

“This joint product-level standard reflects the deepening of our collaboration with GHG Protocol and our shared commitment to global consistency in GHG accounting. As expectations for accurate product-level emissions data rise, organizations need clear, credible methodologies they can trust and apply. By combining the strengths of both systems and drawing on broad technical expertise, we aim to deliver a standard that supports actionable climate strategies, strengthens market confidence, and enables more effective decarbonization across supply chains,” Sergio Mujica, ISO Secretary General said.

“This announcement marks another step toward global convergence in greenhouse gas accounting under our partnership with ISO. By aligning our efforts and inviting broad participation, we are laying the groundwork for a standard that is coherent, inclusive, and practical. Our shared goal is to ensure that all systems – from traditional approaches to emerging digital infrastructures – can connect to a common methodological foundation,” Geraldine Matchett, Chair, Steering Committee Chair, GHG Protocol said.  

Call for Experts

GHG Protocol is inviting experts with technical knowledge and practical experience in areas such as product-level GHG accounting, life cycle assessment, and value chain emissions to participate in the JWG on behalf of GHG Protocol. The organization also welcome experts working on emerging frameworks to exchange product-related GHG data across the value chain to help shape a standard that is both robust and future-ready.

“Developing a globally relevant product-level GHG standard is a collective effort – we invite experts from across disciplines, sectors, and regions to be part of this. Together, we can build a standard that reflects the complexity of real-world systems and supports effective climate action,” Alexander Bassen, Chair, Independent Standards Board, GHG Protocol said.

How to Apply

Experts are invited to submit an Expression of Interest through this form. Applications are due by November 30th, 2025, but we strongly encourage early submissions. Applications will be reviewed on a rolling basis to allow for timely onboarding and to help identify and fill any gaps in expertise as the JWG is formed.

The responsibilities, composition, and expectations of the JWG will be outlined in forthcoming Terms of Reference.
