Ordos city has introduced a new set of technical standards aimed at strengthening greenhouse gas accounting in the coal-chemical industry.

The series, titled Requirements for Greenhouse Gas Emission Accounting and Reporting in the Coal-Chemical Industry, was released under the leadership of the Ordos Inspection and Testing Center.

The standards cover six core coal-chemical segments – coal-to-methanol, coal-to-liquid, coal-to-olefins, coal-to-synthetic natural gas, coal-to-ethylene glycol, and coal-to-urea – filling a gap in carbon accounting guidelines for sub-sectors of the industry. They are expected to support the industry's green and low-carbon transformation and lay a solid technical foundation for its future inclusion in the national carbon market.

Designed around the industry's complex and diverse processes, wide-ranging emission sources, and highly interconnected production links, these standards address key challenges such as inconsistent accounting methods and unclear system boundaries. They establish a scientific, systematic, and highly operable framework for greenhouse gas accounting.

The standards define clear boundaries for enterprise-level carbon accounting, helping prevent deviations and data disputes caused by ambiguous scopes. They map emission points across the entire production chain – from raw material processing and energy conversion to product synthesis and waste treatment. They also standardize accounting methods, data collection, and data quality management to ensure emissions data are measurable, traceable, and reportable.
