Note: Emissions are presented on an adjusted equity basis. 1. The compliance period for the Safeguard Mechanism is from 1 July to 30 June and does not align with our calendar year reporting. So the carbon credits used towards our 2024 net emissions calculation include Australian Carbon Credit Units (ACCUs) that were retired for compliance for the period 1 January to 30 June 2024 plus a projection of the number of ACCUs we expect to retire for the period 1 July to 31 December 2024. See Nature-based solutions section on pages 56 - 57 for further detail.

Strategic report | Our approach to ESG | Climate Action Plan

Progress, lessons learned and our approach today Our approach to decarbonising our operations has evolved since 2021 when we first set our targets and CAP. This is partly due to the challenge of developing new technologies and implementing large-scale physical infrastructure projects. We have also found opportunities to contract renewable electricity and use renewable diesel.

| Aim to install 1GW ofwind and solarcapacity in thePilbara (using ourcapital)                      |     | The emissions reductions we have achieved since 2018 are mostly the result of decarbonising power, but developing large-scalerenewables projects in the Pilbara has taken longer. We need timeto engage with Traditional Owners and to find appropriate sites. Inaddition, as we do not expect to deploy battery-electric haul trucks in the Pilbara before 2030, we now estimate we requireapproximately 600-700MW of renewable power capacity to displace 80% of our gas consumption for power generation. We are makingprogress and have now completed construction of a 34MW solar power plant at Gudai-Darri along with battery storage at Tom Price.Together with the Ngarluma Aboriginal
