1 Scope

GB/T 32151.28-2024 is the mining part of the Chinese greenhouse gas accounting and reporting series. A mine's inventory has an element that no factory's has: fugitive methane released from the strata during extraction and afterwards, which in a gassy coal mine can exceed everything the machinery burns, and which has to be estimated from ventilation air measurements and drainage records rather than from a fuel invoice. Around it sit the ordinary terms, diesel for haulage and loading, explosives, electricity for hoisting, ventilation, dewatering and beneficiation, and the fuel burnt in the ancillary plant. The standard sets the accounting boundary of a mining enterprise, the measurement and monitoring requirements, the calculation steps and methods for the fuel combustion, process and fugitive emissions and for purchased energy, the data quality management and the content and format of the report, with informative annexes giving the reporting template and the default parameter values. It takes effect on 1 April 2025.

This document specifies the accounting boundaries, accounting and reporting scope, accounting steps and methods, data and other aspects of greenhouse gas emissions of mining enterprises. Quality management, report content and format, etc. This document applies to the accounting and reporting of greenhouse gas emissions by mining enterprises.
