Our technology: the Climate Risk Engines
The Climate Risk Engines were created in 2012.
Developed by scientists, engineers and climate risk experts, this was the first time the cost of physical climate risk had been quantified in this way.
Today, the Climate Risk Engines are one of the most flexible, powerful and trusted sources of physical climate risk data in the world.
The Climate Risk Engines use engineering-based methods to assess exposure and vulnerability of asset archetypes to understand the likely damage and failure probability of assets caused by extreme weather and climate change hazards.
The coverage is global, granular, sophisticated and under constant improvement.

The Climate Risk Group’s science team is continually adding new hazards to our analysis. We prioritise those that have the greatest impact on people, business and finance, and the widest application.

Our latest data release
At XDI, we believe that data needs to be in the hands of those who will use it to drive change, including citizens and civil society organisations. We release information publicly to generate debate and increase understanding.
Measuring Corporate Resilience Whitepaper 2025
Measuring Corporate Resilience: The Case for Performance-Based Adaptation.
This white-paper proposes a breakthrough approach to adaptation reporting: the P-FIVE framework. The P-FIVE model focuses on what matters most — the performance outcomes of adaptation measures — enabling machine-readable, scalable reporting that can help companies demonstrate resilience and allows stakeholders to accurately assess and compare physical climate risk.
Adaptation is no longer optional. As climate hazards intensify, companies that transparently report their adaptation strategies as part of their physical climate risk analysis, and alongside their emissions reductions, will be best positioned to secure capital, maintain operations, and build long-term value. The P-FIVE framework can offer a clear, actionable path for businesses to show how they are safeguarding their assets, employees, and communities in a warming world.

Statement on fossil fuels and weapons industry
XDI chooses not to provide services wholly directed towards enabling the expansion of fossil fuel production and use. Specifically, we will not provide physical risk analysis for new sites for coal mines, gas or oil fields or coal or gas-fired power plants. XDI recognises that many of our existing clients and resellers provide lending, consulting services or other support to the fossil fuel industry, including its expansion. XDI views our work as crucial to helping our clients understand the costs of catastrophic climate change and informing their business decisions and strategies such that they pursue pathways towards rapid decarbonisation and resilience. On a case by case basis, XDI may choose to add a company to the list of prohibited companies appended to this policy if XDI deems that company to be contributing to the expansion of the fossil fuel industry without appropriate plans to phase out these activities.
In view of the extensive and irreparable harm caused by the international weapons industry, XDI will not provide business services to companies that dominate this industry. XDI chooses not to provide services to companies, including their associated entities, whose business depends upon the continuation of war and conflict and the misery and environmental damage it inflicts. Specifically, XDI will not provide services to those among the 100 largest weapons manufacturers that derive 50% or more of their revenue from weapon sales. These companies will be those identified by the Stockholm International Peace Research Institute in 2021 or their associated entities.
