1 Scope

GB/T 32151.43-2024 is the lead smelting part of the Chinese greenhouse gas accounting and reporting series. China smelts more lead than the rest of the world combined, from both concentrate and, increasingly, from recycled battery scrap, and the two routes have quite different emission profiles: the primary route carries process emissions from the reduction of the ore with carbonaceous reductants and from the flux carbonates, while the secondary route is dominated by fuel and by the organic material entering with the scrap. The standard sets the accounting boundary of a lead smelting enterprise, the measurement, monitoring and testing requirements, that is what must be weighed, metered and analysed, and the calculation steps and methods for the fuel combustion, process and purchased energy emissions, followed by the data quality management and the report. Informative annexes give the default parameter values and the data quality guidance. For a smelter, an auditor or a buyer of Chinese lead asking for a carbon figure, this is the method behind the number. 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 lead smelting enterprises. Data quality management and report content and format. This document applies to lead concentrate, crude lead, lead-containing materials (waste lead storage batteries, metallic lead waste and other lead-containing materials) as raw materials. Calculation and reporting of greenhouse gas emissions from lead smelting enterprises, including mineral lead smelting enterprises and recycled lead smelting enterprises.

3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Greenhouse gas The natural and human-caused gases in the atmosphere that absorb and emit radiation from the Earth's surface, atmosphere, and clouds. The gaseous component of radiation with wavelengths in the infrared spectrum.

Note. The greenhouse gases referred to in this document include only carbon dioxide (CO2). [Source: GB/T 32150-2015, 3.1, modified]
