Experts convened in Guangzhou, China from 10 – 15 October 2025, kickstarting the development of a standard Data Model for Carbon Credit Markets (ISO/AWI TS 32214) under the ISO Technical Committee 322 (Sustainable Finance) Working Group 5 (ISO/TC 322/WG 5). WG 5 is convened by Alvin Lim (Singapore) and supported by project leaders, Evan Kong (Singapore) and Dr Lao Weilun (People’s Republic of China).
The proposed standard is in the preparatory stage, and experts are preparing the working draft for review. The Reference Data (Model/Schema) seeks to identify key attributes that support the financing, tracking and trading of carbon credits. The development of this standard taps on the expertise of existing initiatives in the carbon markets. This includes the work of CAD Trust, G20-initiated Common Carbon Credit Data Model supported by the Climate Data Steering Committee, and the Carbon Data Open Protocol, all of which are contributing actively as nominated experts of WG 5.
This standard is a step forward in global cooperation to develop common data practices and enhance coordinated guidance for scaling efficient carbon markets to deliver climate finance. The working draft is expected to be finalised in 2027 for public consultation.
Developing ISO standards is an international, multi-stakeholder and consensus-driven process. Interested parties may get involved through their respective national standards bodies.
