China National Standards for CCUS (GB Series)

The GB/T CCUS system record predates the January 2026 twelve-standard package (covered in cn-ccus-national-standards-2026) and remains the system-level entry: capture efficiency, pipeline safety, saline-aquifer monitoring and utilisation-product environmental assessment as the standing technical red lines for Mt-class demonstrations, with ISO alignment as the export strategy. Read the two records as system (this one) plus package (the 2026 one): the system sets the standing rules, the package adds the dated instruments. Its scores below reflect the system role — methodology base for carbon-market accounting and operating-risk reduction — while dated standard numbers live in the package record.
