1 Scope

GB/T 32151.24-2024 is the greenhouse gas accounting and reporting requirement for electronic equipment manufacturers, part of the Chinese sector series. Electronics is a distinctive case in carbon accounting, and the reason is not electricity: it is the process gases. Semiconductor and display fabrication uses perfluorocarbons, nitrogen trifluoride and sulfur hexafluoride, whose global warming potentials run into the thousands and tens of thousands, so a small mass leaking or passing uncombusted through an abatement unit dominates the whole inventory. The standard sets the boundary of the reporting entity and of the emission sources, the accounting method for the fuel combustion, process and fugitive emissions and for purchased electricity and heat, the treatment of the process gases including the emission factors and the abatement efficiency and how it must be evidenced, the activity data requirements and their quality, the calculation of the total, the reporting format and the records to be retained. For an electronics manufacturer reporting in China, or a customer asking for the number, this is the method behind it.

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