1 Scope

GB/T 32151.29-2024 is the mechanical equipment manufacturing part of the Chinese greenhouse gas accounting and reporting series, and it applies to an enormous population of Chinese factories. For a machinery maker the emissions are mostly indirect, purchased electricity for machining, assembly, compressed air and lighting, with direct emissions from heat treatment furnaces, welding gases, painting ovens and the plant boiler; the accounting difficulty is not the physics but the boundary, since these firms buy castings, forgings and components rather than making them and the line between the enterprise's own emissions and its supply chain has to be drawn consistently. The standard sets exactly that boundary, then the measurement and monitoring requirements, the calculation steps and methods for each emission source, 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. It takes effect on 1 April 2025.

This document specifies the accounting boundaries, accounting steps and accounting procedures for the accounting and reporting of greenhouse gas emissions of machinery and equipment manufacturing enterprises. Methods, data quality management, report content and format. This document applies to the accounting and reporting of greenhouse gas emissions by machinery and equipment manufacturing enterprises.
