1 Scope

GB/T 32151.47-2024 is the man-made fibre part of the Chinese greenhouse gas accounting and reporting series, and China produces the great majority of the world's chemical fibre. The sector's emissions are dominated by energy: polymerisation and spinning need large quantities of steam and electricity, and drawing, texturing and heat setting add more, while the direct process term includes the nitrous oxide and other emissions specific to particular polymer routes and the solvent-recovery systems of the cellulosic processes. The standard sets the accounting boundary of a chemical fibre production enterprise, the measurement and monitoring requirements, the calculation steps and methods for the fuel combustion, process and purchased energy emissions, the data quality management and the content and format of the report, with informative annexes giving the reporting template and the default values of the parameters. For a fibre producer, or for a textile brand asking a Chinese supplier for a verified emissions figure, this is the method behind the number. It takes effect on 1 May 2025.

This document defines the terms and definitions for greenhouse gas emissions accounting and reporting by chemical fiber production enterprises, and stipulates the accounting boundaries, measurement, monitoring, and It also describes the measurement and testing requirements, data quality management, report content and format, and the accounting steps and methods. This document applies to the accounting and reporting of greenhouse gas emissions by chemical fiber production enterprises.
