On 29 July 2026, GHG Protocol and the International Organization for Standardization (“ISO“) announced plans to develop a single global corporate greenhouse gas (“GHG“) accounting standard (“New Corporate Standard“). The initiative aims to reduce fragmentation across reporting frameworks and provide a more consistent and interoperable foundation for climate-related reporting worldwide. Its Standard Development Plan is available here.

The New Corporate Standard will integrate the GHG Protocol’s Corporate Standard, Scope 2 Guidance, Scope 3 Standard and the developing Actions and Market Instruments framework with ISO 14064-1. A consolidated public consultation is planned for Q2 2027, while publication of the final version of the New Corporate Standard is expected in Q4 2028.

The development of the GHG Protocol’s standards has long been dominantly supported by the World Business Council for Sustainable Development (“WBCSD“), one of the initiative’s founding partners together with the World Resources Institute (WRI). CBCSD is a partner organisation of WBCSD and oversees the development of the New Corporate Standard on a continuous basis in particular via monthly WBCSD Global Partner Network meetings.
