Recently, State Administration for Market Regulation (SAMR) and National Standardization Administration of China (SAC) released 12 national standards for carbon capture, utilization and storage (CCUS), which will come into effect on July 1, 2026.
CCUS is a globally recognized key technological means for achieving the goal of carbon neutrality. The standards released this time cover important processes such as carbon capture, transportation, and storage, as well as basic links such as terminology and emission reduction assessment.
As for carbon dioxide capture, standards such as GB/T 46877-2025, Carbon dioxide capture—General requirements for post-combustion CO2 capture system, stipulate the classification, composition, and technical requirements of post-combustion carbon capture systems, as well as evaluation methods for key performance indicators, operation evaluation, and management requirements.
As for carbon dioxide transportation, GB/T 46875-2025, Quality requirements for carbon dioxide medium entering long-distance transportation pipeline, determines the quality indicators, sampling, testing methods, and inspection rules for the medium entering long-distance transportation pipelines.
As for carbon dioxide storage, standards such as GB/T 46878-2025, Carbon dioxide capture, transportation and geological storage—Geological storage, specify the screening, selection, and evaluation methods for the storage sites, and clarify the evaluation methods for storage volume, the design of injection operation plans and risk management, as well as the requirements for storage engineering management.
As for commonalities and general requirements, standards such as GB/T 46872-2025, Carbon dioxide capture, transportation and geological storage—Vocabulary—Cross cutting terms, systematically define key terms and delineate the accounting boundaries, processes and methods for the greenhouse gas emission reduction of CCUS projects.
These standards will effectively unify basic concepts, provide unified technical specifications, testing methods and evaluation standards for key CCUS processes. They will promote technological innovation and industrial application along the CCUS chain, and contribute to carbon reduction and high-quality development.
