 updated our reporting methodology and now use market-based Scope 2 emissions in our primary metric and target.Consequently, the Bell Bay Aluminium and ISAL smelters, which are physically co-located and contracted with hydropower facilities, nowreport emissions under this new methodology.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |

We face two underlying challenges in delivering net reductions in absolute emissions. First, production growth increases emissions and we need additional abatement to address this. This growth may be brownfield (such as in the Pilbara) or greenfield (such as Simandou). And secondly, in our existing mining operations, increasing work indexes, with longer haul distances and declining ore grades, typical for the mining sector, mean that more energy is required to achieve the same level of production output. Our adjusted gross Scope 1 and 2 emissions were 30.7Mt CO 2 e in 2024. In 2024 we made significant progress and reduced our emissions by 3.2Mt CO 2 e. This has primarily been achieved by new renewable energy contracts, including the limited use of unbundled renewable energy certificates in locations where new generating assets are under development or where power purchase agreements have been agreed . In addition we have made commitments to projects that are expected to deliver abatement of around 3.6Mt CO 2 e per year in future periods mostly through renewable electricity and biofuels. In addition, imminent investment decisions could deliver further abatement by 2030 and include new energy solutions at BSL and fuel- switching and electrification in the Queensland Alumina Limited (QAL) and Yarwun alumina refineries. Our 2025 target is to reduce net emissions by 15% below 2018 levels. In 2023, we reported that while we expected to have committed to abatement projects representing more than 15% of group emissions, that delivered abatement would lag this target. Since then, we have executed a number of commercial partnerships and transactions that have allowed us to decarbonise faster. We have now reduced gross operational emissions, by 14% below our 2018 levels. After applying high integrity offsets our net Scope 1 and 2 emissions are 17% below our 2018 baseline. Progress on abatement will not be linear. Delays are the result
