 Scope 1 and 2 emissions and are aligned with 1.5°C pathways. We adjust our baseline to exclude reductions achieved by divesting assets and to account for acquisitions. Our definition of net zero applies to our operational (Scope 1 and 2) emissions on an equity basis. See pages 49 - 57 for detail on how we are reducing emissions in our own operations. Scope 1 emissions are direct GHG emissions from facilities fully or partially owned or controlled by Rio Tinto. They include fuel use, on-site electricity generation, anode and reductant use, process emissions, land management and livestock. Scope 2 emissions are GHG emissions from the electricity, heat or steam brought in from third parties (indirect emissions). This is consistent with the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD)’s Greenhouse Gas (GHG) Protocol: A Corporate Accounting and Reporting Standard (Revised Edition) (2015).

See our 2024 Scope 1, 2 and 3 Emissions Calculation and Climate Methodology report and our 2024 Sustainability Fact Book for further detail on our emissions reporting methodology. We engaged KPMG to provide reasonable assurance over the 2024 Scope 1 and 2 data. Changes to our 2018 baseline include: Review of Scope 1 emissions factors and greater alignment with regional factors specified in government reporting (<1% change to emissions). Acquisitions and divestments: Addition of Matalco aluminium metal recycling assets into reporting and baseline. Acquisition of Mitsubishi's interest in Boyne Smelters (11.65%), Sumit
