IAI Scope 3 Calculation Tool & Guidance

Published in

2022

The International Aluminium Institute (IAI) Scope 3 Calculation Tool is designed to evaluate Scope 3 emissions for the aluminium value chain based on the GHG protocol guidelines.

This Guidance document facilitates commonly understood and harmonised Scope 3 GHG emission calculations within the primary aluminium value chain. It is based on the Corporate Value Chain (Scope 3) Accounting and Reporting Standard, containing a materiality assessment for 15 categories in each primary aluminium value chain production step. This Excel-based Tool utilises the user’s input data and publicly available emission factors to generate an indicative result and can also be used together with aluminium sector-specific tools that are available on the GHG Protocol website.

A simple illustration depicts a cloud with "CO2" written inside it and a sun partially visible behind. Below the illustration, the words "GREENHOUSE GASES" are displayed against a teal background, brought to you by the International Aluminium Institute.

Reference document on how to treat scrap flows in carbon footprint calculations for aluminium products

In 2022, the IAI published Guidelines on Transparency that state that when reporting the cradle-to-gate carbon footprint of products that contain scrap there should be full transparency on the methodology used for the carbon footprint calculation. This reference document, summarising three potential approaches, should serve aluminium producers to disclose the methodology they ...
