Fathom and Altitude expand collaboration to strengthen real-world climate adaptation decisions for investors and corporates

Intro

Fathom and Altitude, AXA Climate’s climate risk platform, today announce the expansion of their collaboration to further integrate Fathom’s probabilistic models into Altitude’s decision-support platform for investors and corporates.

This initiative reflects growing demand for scientifically robust flood hazard data that can be translated into clear financial and resilience insights. Altitude is using Fathom’s models to support investors and corporates in assessing exposure and informing capital allocation decisions in response to the rising cost of physical climate risks.

The integration includes data from FathomDEM+, Fathom’s latest terrain model, which uses machine learning to deliver near-LiDAR-quality elevation data globally, improving the accuracy of flood hazard assessment across portfolios and regions.

The Altitude platform leverages physical indicators – such as water depth for various probabilities – to assess flood risk by asset type and provide accurate adaptation recommendations.

“Working with Fathom helps us provide scientifically validated risk assessments ready for real-world decision making. The probabilistic nature of their models allows us to quantify multi-peril flood hazards across a wide range of scenarios. This gives our clients an unparalleled view of exposure, supporting precise risk pricing and capital allocation as global climate risk intensifies.” 

– Théophile Bellouard, VP of Altitude, AXA Climate.


“After three years of working together, we’re delighted to evolve our collaboration with Altitude. Seeing our models embedded within platforms like Altitude is a strong validation of our glass-box approach and the growing expectation that financial risk decisions are grounded in transparent, defensible science.”

– Harry Vardigans, Head of Insurance at Fathom.

Founded at the University of Bristol in 2013, Fathom is a leading provider of global flood risk intelligence for the world’s largest insurers, financial institutions and engineering organizations.

Based in Paris, Altitude is AXA Climate’s science-based climate and nature-related risk platform, supporting investors and corporates to develop sustainable investment strategies and strengthen the resilience of their value chain.
