T/CAB 0417-2025 “Low-carbon Hydrogen, Clean Hydrogen and Renewable Hydrogen” Chain of Custody
Basic Information
Scope
This document stipulates the general requirements for the implementation of the supervision chain of the production and sale of clean hydrogen, low-carbon hydrogen, and renewable hydrogen; the special requirements for each link; and the methods of supervision chain and declaration. This document applies to the supervision of the production and sale of low-carbon hydrogen, clean hydrogen, and renewable hydrogen that have been evaluated and labeled in accordance with T/CAB 0403—2025, "Greenhouse Gas Product Carbon Footprint Quantification Methods and Evaluation—Hydrogen". This document establishes transparent and traceable standards for the supervision chain of production and sale, ensuring the transfer of the low-carbon attributes of the hydrogen energy industry chain and the quantifiability and verifiability of the green attributes of hydrogen products, thereby providing technical support for carbon market transactions, green financial innovation, and international hydrogen trade. It stipulates the requirements for the implementation of the supervision chain of the production and sale of clean hydrogen, low-carbon hydrogen, and renewable hydrogen.
