 machinery, electrical equipment) of 3.0Mt CO 2 e. Due to the nature of our businesses, many of our purchased inputs are from hard- to-abate sectors, such as caustic, coke, pitch and steel. In accordance with Rio Tinto’s stated position to put the energy transition at the heart of our strategy, in 2024 we launched our Sustainable Procurement Principles and revised Supplier Code of Conduct , outlining the expectations we have for ourselves and our suppliers to strive to ensure that the procurement of our goods and services aligns with our commitment to strive for impeccable ESG credentials and responsible business practices. We expect our suppliers to share this commitment to environmental responsibility. We work with more than 20,000 suppliers across complex multi-layered supply chains. To address upstream emissions, we are taking a systematic approach, prioritising engagement with 50 of our highest-emitting suppliers (representing over 40% of our procurement-related emissions), and referencing decarbonisation as evaluation criteria for new sourcing in high-emitting categories. The prioritisation of suppliers and categories followed the assessment of the sources of emissions across the Global Procurement portfolio (and available abatement pathways) and deliberately focuses our efforts on the largest sources. Ongoing refinement of the measurement and reporting methodology will inform our priorities in future. In 2024, we issued a baseline questionnaire to inform our engagement with 50 high- emitting suppliers, and returned a 100% response rate. We validated and discussed responses in follow-up supplier engagements with a focus on understanding maturity, opportunities for partnership and improvement opportunities. We have now developed and implemented decarbonisation criteria to evaluate new sourcing in high emissions categories. In 2025, we will sustain and deepen engagements with the 50 high-emitting suppliers, building on 2024 engagements and continue to reference decarbonisation criteria to evaluate new sourcing in high emissions categories. 1.
