 our value chains. For further details, refer to our 2024 Scope 1, 2 and 3 Emissions Calculation and Climate Methodology report. We engaged KPMG to provide limited assurance on Scope 3 emissions estimates in 2024. 1. To identify and calculate Scope 3 emission sources across our operations, we have used the WRI and WBCSD, Greenhouse Gas (GHG) Protocol: A Corporate Accounting and Reporting Standard (Revised Edition) (2015), GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard (2013) and the Technical Guidance for Calculating Scope 3 Emissions (version 1.0). We estimate the emissions from our customers' processing of iron ore, bauxite, alumina, titanium dioxide, salt and copper concentrate using a combination of internal emissions modelling, regional and industry level emissions factors and production and sales data. Third party shipping and transportation of our products to our customers, intercompany transport of products and transport of fuel and other supplies are also calculated and reported. Emissions associated with the manufacture and supply of purchased and capital goods are included in the Scope 3 inventory. Scope 3 emissions deemed to be material at Group level are reported on an equity basis as part of our disclosures in the Annual Report and our submission to the Carbon Disclosure Project. Where there are significant changes to the calculation methodology of Scope 3 categories to improve the maturity and accuracy of reported emissions, an approximate equivalent to the historical reported numbers using the new methodology will be provided.
