. In assessing the risk of various hazards under different emissions scenarios projected for 2050, there is a notable shift in the risk profile for various perils across our operating sites. The number of sites at risk from coastal inundation, riverine flood and surface water flood increase under both future emission scenarios. Of all hazards, riverine flood sees the largest increase by 2050 under a high emissions scenario. The number of operating sites at risk from cyclonic wind, extreme wind, forest fire, freeze-thaw and soil subsidence is not expected to materially change with future emissions scenarios. Considerations and limitations Our climate physical risk modelling acknowledges limitations and uncertainties due to the dynamic nature of the Earth’s climate and unpredictable future GHG emissions. These models represent plausible futures, not predictions, and are useful for assessing risks and informing strategic decisions. The accuracy of our analysis depends on the quality of asset data and assumes no changes in operations or design standards. Each asset is assigned an archetype, which may not fully capture its unique characteristics, affecting the risk profile. This analysis is iterative, evolving with new insights and projections. We plan to update it regularly to reflect changes in our asset base, guiding our physical resilience program.
