1 Scope

China's national requirements for greenhouse gas emission accounting and reporting by carbon material production enterprises. It is Part 34 of GB/T 32151 and specifies the accounting boundary, the calculation steps and methods, the data quality management, and the content and format of the report, with a schematic of the accounting boundary for a typical carbon material plant, a report format template, default parameter values, a data quality control plan template, and a normative annex on the value requirements and supporting documents for the emission factor of non-fossil energy electricity. Carbon materials are the graphite electrodes used in electric arc steelmaking, the carbon anodes consumed in aluminium smelting, and the specialty graphites used in nuclear, semiconductor and battery applications. Their production has an emissions profile shared with almost no other sector, for two reasons. The first is that the raw material is carbon: petroleum coke and coal tar pitch are calcined, mixed, formed and baked, and a substantial fraction of the carbon put in leaves as carbon dioxide rather than as product - the volatile matter driven off during calcination and baking is burnt, and the binder pitch loses much of its mass. That is a process emission, not a combustion one, and it happens whatever fuel the plant uses. The second is graphitisation: the baked article is heated to around three thousand degrees Celsius by passing an electric current through it, which is one of the most electricity-intensive operations in any industry. The normative annex on non-fossil energy electricity is therefore the part with the largest commercial consequence here, since it sets what a producer must demonstrate to claim a lower factor for renewable power. Issued on 23 August 2024 and in force since 1 March 2025.

This document specifies the accounting boundaries, accounting steps and methods, data quality management, and management, report content and format. This document applies to the accounting and reporting of greenhouse gas emissions from carbon material manufacturing enterprises.
