 assess future extreme events and inform risk and resilience assessments, operational strategies and financial planning. Climate change projections are available for every site in our portfolio (including non- managed assets). Down-scaled climate change projections are available for over 60 climate change variables and future emission scenarios from the IPCC Coupled Model Intercomparison Project 5 and 6 (CMIP5 and CMIP6). We have completed flood risk modelling for 100% of our managed and non-managed assets. These span present- day, medium and long-term time horizons. 2. Physical risk identification and assessment Our approach to quantifying and assessing physical risk covers individual assets (bottom-up) and Group level (top-down). We first identify climate risks and opportunities across varying time horizons and emission scenarios. Next, we evaluate their potential financial and non-financial consequences and likelihood, then we prioritise these risks by materiality for effective risk management and appropriate resource allocation. This process is integrated within the Rio Tinto Risk Management Information System. The scope of our assessments includes our operations and the environments in which we operate, our people, the communities who host us and our supply chain. 3. Resilience planning and adaptation Our resilience planning identifies the most appropriate resilience measures to manage climate risks and adapt to them. We comprehensively evaluate an investment decision before funding is approved. This includes prioritising projects and engaging key stakeholders to seek alignment on the investment and its implementation. 4. Monitoring and evaluation We actively and regularly monitor risks, with clearly defined roles and responsibilities. We continually evaluate the latest generation of climate change data and emerging technologies to assess the risk profile of our assets and infrastructure over time. Where we have identified a material change to the economic, social, environmental or physical context of the risk, we revisit the assessment process.

Risks and impacts We have identified 8 Group-level material physical climate risks. The table below takes into account both the short-term risk that could emerge during current operations and the long-term risk associated with climate change.
