 trials were successfully carried out at RBM and RTIT Quebec Operations sites this year, thus completing industrial qualification. And, at IOC, we completed a plant trial of substituting coke with biocarbon. In 2025, we aim to develop bioenergy supply sources (biofuel and biocarbon) to support the industrial ramp-up of the new joint venture Évolys TM . We also plan to complete phase 2 of the BlueSmelting™ technology validation and the installation and commissioning of an electric boiler at IOC.

Nature-based solutions

| Nature-based solutions and carboncredits decarbonisation spend1$70m(2023: $45m) |

In 2022, we set up a team dedicated to developing and investing in nature-based solutions near our operations, because we believe they are a win for people, nature and climate. Over the last 2 years, we developed our high-integrity criteria - based on our own standards as well as international best practice, guidance and principles. We have identified new projects to develop and existing ones to scale up, and partnered with NGOs and other experts to deliver our program. Today, we are on track to enable 500,000 hectares of high-integrity nature-based solutions across Argentina, Australia, Guinea, Madagascar and South Africa by the end of 2025. These projects are enablers for activities that support sustainable livelihoods for the communities where we operate, while protecting and restoring nature, and delivering high-quality carbon credits. Our projects complement structural abatement. How we use carbon credits We anticipate that we will retire approximately 1.1 million Australian Carbon Credit Units (ACCUs) for compliance with the Safeguard Mechanism for the calendar year 2024. In alignment with our updated CAP, we will limit the use of voluntary and compliance carbon credits towards our 2030 climate target to up to 10% of our 2018 baseline emissions (~3.6 million). Carbon credits retired as offsets towards our climate targets must pass our due diligence assessment, including meeting our high-integrity criteria.
