T/AIAC 009-2024 Green aluminum carbon footprint evaluation criteria

Scope

Main Technical Content: 1. Scope This document specifies the general requirements, quantification methods, evaluation system, evaluation methods, and evaluation results for the evaluation of the green aluminum carbon footprint. This document is applicable to the evaluation of the green aluminum carbon footprint. 2. Normative References This document does not have any normative references. 3. Terms and Definitions The following terms and definitions are applicable to this document. - **Green aluminum**: Aluminum products produced using green electricity, green processes, and recycled aluminum during the life cycle of the aluminum product, with the aim of mitigating climate change. Note: This document only refers to electrolytic aluminum. - **Green aluminum carbon footprint**: The greenhouse gas emissions during the life cycle of a green aluminum product, from the input of raw materials to the factory output, expressed in carbon dioxide equivalents. - **Greenhouse gas**: Gaseous components in the atmosphere that naturally exist or are produced by human activities, capable of absorbing and emitting radiation in the infrared spectrum from the Earth's surface, atmosphere, and clouds. Note: The greenhouse gases covered in this document are carbon dioxide (CO2) and perfluorocarbons (PFCs).

[Source: GB/T 32150-2015, 3.6] - **Process emission**: Greenhouse gas emissions from physical or chemical changes during production, waste treatment, and other processes, excluding fuel combustion. [Source: GB/T 32150-2015, 3.8] - **Emission factor**: A coefficient that characterizes the greenhouse gas emissions per unit of production or consumption activity. [Source: GB/T 32150-2015, 3.13] - **Functional unit**: A unit used as a reference for quantifying the perfor
