PUBLIC REVIEW: Reference Document on Carbon Footprint Calculations of  Aluminium Scrap

International Aluminium Institute’s reference document on how to treat scrap flows in carbon footprint calculations for aluminium products

Welcome to our public review! We value your input on this topic very much.

Thank you for participating in the public review for the International Aluminium Institute on how to calculate the cradle-to-gate carbon footprint of aluminium products containing recycled aluminium. 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 all potential approaches, should serve aluminium producers to disclose the methodology they are using to calculate the carbon footprint of their products in a transparent way. This document is based on a research project executed by life cycle assessment and eco-design consultancy Solinnen for IAI on the same topic.  

Responses will be accepted from 9th January – 6th February 2023.

Please find the IAI reference document and an excel tool using three selected methodologies for a complex scrap flow system for download here.

Please add your comments to the ”Comment Template” and email it to: Marlen Bertram, IAI’s Director – Scenarios & Forecasts.

All comments will be analysed, and the reviewer will be informed by the practitioner if modifications were performed or the reason why the comment was not considered.
