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.
