1 Scope

GB/T 32151.21-2024 is the foundry part of the Chinese greenhouse gas accounting and reporting series. A foundry's emissions come from three distinct places and the standard keeps them apart: the fuel burnt in cupolas, rotary and other melting furnaces, the very large electricity draw of induction and arc melting, and the direct process emissions from the carbon that is oxidised in the charge, from the carbonate fluxes and from the binder and carbonaceous additives that burn off in the mould. China casts more metal than any other country and the sector is highly fragmented, so a common method matters more here than in a concentrated industry. The standard sets the accounting boundary of a foundry enterprise, 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, 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 requirements, accounting steps and methods, and data for greenhouse gas emissions of foundries. Data quality management, report content and format. This document applies to the accounting and reporting of greenhouse gas emissions from foundries.
