Aon's Impact Forecasting has evolved traditional catastrophe modelling for reinsurance by encompassing underwriting, new product development, and automated accumulation control to help insurers make strategic decisions. As a result, insurers can streamline their catastrophe modelling workflows.

Aon has continued to update and refine its ELEMENTS catastrophe modelling platform, which forms part of the Impact Forecasting Toolkit. This helps catastrophe modellers obtain new insights and manage the process from start to finish. This includes the ability to use an insurer's own loss data to customise various model components. It also comes with the reporting capabilities to communicate results to senior management and regulators.

Included within Aon's work this year with the Impact Forecasting platform, has been its support of the Canadian government in the development of its national flood programme using the Impact Forecasting Canada flood model hazard component, and to increase the flood resilience for homeowners in peak flood risk zones. The firm said it had also worked with Malaysian insurers to fulfil the Climate Risk Stress Testing exercise.

Its work was not just limited to Canada and Malaysia. Other major events covered in 2025 included the Myanmar earthquake and floods in the US and Mexico.
