Aon has enhanced the scope of its climate risk monitoring tool to include quantification of tropical cyclone and flood, an enhanced user interface and direct client access. The updates also include a new hazard vulnerability component based on location occupancy types.

Climate Risk Monitor was introduced to clients last year with the aim of providing analyses of climate impact on a range of chronic and acute perils including flood, drought, extreme rainfall, extreme heat, freeze, tropical cyclone and wildfire under different climate change scenarios.

The new functionality includes: identification of clients’ riskiest individual locations and geographical concentrations of risk; the most impactful perils on individual assets and portfolios; geographical visualisations of changing risk; and risk assessment methodology and uncertainty for regulatory and reporting purposes.

Global insured losses from natural disasters in 2024 were estimated at US$145bn according to Aon’s 2025 Climate and Catastrophe Insight report.

Aon says its Climate Risk Monitor provides insights into the potential impacts of these
events, enabling businesses to make informed decisions and build resilience against future climate-related challenges.”

In December 2024, Aon announced a collaboration with flood expert, Fathom, to add high resolution data functionality across flash flooding, river flooding, coastal flooding and rising sea levels. It enables clients using the solution to assess US, UK and Japan flood risk at a resolution of 10 sqm, and 30 sqm for other regions globally.
