The application window to participate in the Joint Working Group (JWG) to develop the new product-level GHG accounting standard in partnership with ISO officially closed on November 30, 2025. We are excited to share that we received 459 applications from across sectors and regions. We sincerely thank everyone who applied and expressed interest in contributing to this important work.  

The GHG Protocol Secretariat is now conducting a thorough review of all applications received and will propose a selection of candidates for the GHG Protocol Independent Standard Board approval. If specific gaps are identified during this process, the Secretariat will recruit additional members on a rolling basis to address those gaps. Confirmations of acceptance and the list of selected JWG members will be communicated publicly in the first quarter of 2026.

Actions and Market Instruments Technical Working Group In-Person Workshop

The Actions and Market Instruments (AMI) Technical Working Group (TWG) met earlier this month in Washington D.C., to discuss the AMI White Paper currently in development, which will be the basis for a public consultation in Q1 of 2026.  

More than half of the TWG joined in person, while other participants joined online. In their feedback, participants highlighted that they particularly appreciated the live discussions, the spirit of a shared purpose, learning from practical examples from different sectors and the constructive work undertaken in breakout sessions.

"The successful in-person workshop was a milestone in the acceleration of the AMI work. The whole team was deeply impressed by the commitment and engagement of all participants on site and online - even during late hours given the different time zones," said Ralf Pfitzner, acting lead of the AMI workstream.
