In July 2026, the GHG Protocol announced significant updates to its corporate standards development process, marking an important step toward more consistent and globally aligned greenhouse gas accounting.  

Key highlights: 

One Global Corporate Carbon Standard 
GHG Protocol and ISO will work together to develop a single, harmonized corporate carbon accounting standard, reducing complexity and improving global consistency. 

Scope 2 Accounting Update 
The results of the public consultation on Scope 2 accounting have been released, providing valuable insights that will shape future guidance on electricity-related emissions. 

Actions & Market Instruments 
Preliminary feedback from the Request for Information (RFI) on Actions and Market Instruments has been shared, helping define how organizations account for climate actions beyond their value chains and the use of market-based instruments. 

Why this matters 

As climate disclosure requirements continue to expand through frameworks such as CSRD, ISSB, CDP, and voluntary net-zero commitments, organizations need transparent, credible, and interoperable carbon accounting standards. These updates represent a major step toward a globally harmonized approach that will improve comparability, reduce reporting complexity, and strengthen confidence in corporate GHG reporting.
