1 Scope

GB/T 32151.54-2025 is the Chinese national standard covering accounting the emissions of a sulphuric acid plant - the boundary, the fuel and electricity, the process emissions and the credit for the heat exported, since a contact plant is a net energy producer and the accounting has to reflect that honestly. Part 54 of the sector accounting series, first edition. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the accounting boundaries, measurement and monitoring requirements, accounting procedures, and accounting methods for greenhouse gas emissions from industrial sulfuric acid enterprises. Law, data quality management, report content and format. This document applies to the accounting and reporting of greenhouse gas emissions from industrial sulfuric acid plants.
