1 Scope

GB/T 32151.42-2024 is the copper smelting part of the Chinese greenhouse gas accounting and reporting series. China smelts around half the world's copper, and the sector's emissions have a shape of their own: flash and bath smelting are autogenous, so the sulfide feed itself supplies much of the heat and the direct combustion term is smaller than it would be in another metallurgy, while the electricity for the electrolytic refining and for the oxygen plant is very large, and the carbonaceous reductants and fluxes give a process term. The secondary route from scrap has a different profile again. The standard sets the accounting boundary of a copper smelting enterprise, the measurement, monitoring and testing requirements, the calculation steps and methods for the fuel combustion, process and purchased energy emissions, the data quality management, and the content and format of the report, with informative annexes giving the reporting template, the default parameter values and the data quality guidance. It takes effect on 1 April 2025.

This document specifies the accounting boundaries, measurement and monitoring/detection requirements, accounting steps and methods of greenhouse gas emissions from copper smelting enterprises. Data quality management and report content and format. This document applies to the accounting and reporting of greenhouse gas emissions from copper pyrometallurgical smelting enterprises that use copper concentrate or crude and miscellaneous copper as raw materials. This document is not applicable to the accounting and reporting of greenhouse gas emissions from copper hydrometallurgical smelting enterprises that use copper ore as raw material.
