©2023, Rio Tinto, All Rights Reserved 104 In May 2023, our Boron operation became the world’s first open pit mine to go 100% biofuel – reducing up to 45kt of CO2e per annum Biofuels approach • Electrification will be the most efficient and cost-effective pathway to our zero-emission end state for diesel we believe, with meaningful effect post 2030. In the interim, we need to develop and deploy alternative abatement solutions available today, such as biofuels. • Biofuels critical to our transition and pivotal in supporting our near-term emission reduction commitments (2030). It is technically feasible with successful trials at Boron and Kennecott Copper operations. • Key challenge is access to sustainable non-edible feedstock at acceptable product premiums – we must consider the GHG impact across full life cycle of the biofuel (both scope 1 and scope 3). • In current markets, this is challenging and results in product costs higher than diesel fuels and we expect sustainable biofuels will likely continue to be relatively expensive outside subsidised regions. • The pragmatic pursuit of biofuels as an interim decarbonisation solution serves multiple benefits: - Protects us against carbon tax scenarios; - Enables a response to carbon penalties or subsidy opportunities; and - Affords time for suppliers, markets, supply chains and regulators to mature future zero-emission electrification technologies and ensure safe deployment in our operations. • We are exploring opportunities to support the development of the biofuel value chain, influence the type of biofuel feedstock and build scale. Above: Neste MY Renewable Diesel is a Hydrotreated Vegetable Oil (HVO) made from 100% sustainably sourced renewable raw materials – used at Boron Below: Biofuel powered truck at our Boron operations in California Boron case study • In May, we fully transitioned to renewable biofuel at Boron in the U.S, reducing up to 45kt of CO2-e per year. • Boron is the first open pit mine globally to fully transition to renewable biofuel. • Trial conducted in 2022 in partnership with Neste and Rolls-Royce to use Neste MY Renewable Diesel™ - 100% renewable raw materials such as used cooking oil and animal fat waste. • Trial showed trucks with renewable diesel delivered similar performance and reliability to conventional diesel. • Important first step and will lead to further opportunities to decarbonise our operations with biofuels and an excellent example of what can be achieved when partners (State of California, Neste and Rolls-Royce) collaborate toward a carbon reduction goal.

The proposed renewable portfolio to displace the majority of gas usage is value accretive. Partnerships We are exploring a number of innovative solutions to accelerate decarbonisation, such as use of existing land access and post-mine closure land for future renewable developments. This includes collaboration with Traditional Owner groups in the region. Progressing studies We are continuing to study and negotiate the development of the proposed coastal solar farm. We are also pursuing additional opportunities to decarbonise our operations by advancing studies on other sites adjacent to our network (including additional solar/wind and battery solutions). Potential coastal solar site being studied Accelerated schedule with first operations starting from 2027 - 2030 Close proximity to operations, reducing transmission infrastructure spend “This will strengthen our existing partnership and provide long term benefits for our community, while also ensuring that we can protect and preserve the areas of cultural, spiritual and environment significance within our Ngurra.” Michael Woodley, YEC chief executive
