Our values

Our goal is to accelerate action on climate change by embedding physical climate risk data in all decisions

As the physical climate risk experts, we’re here to help you - whether at the start of your journey, or advanced, we deliver actionable results.

We’re independent



XDI is part of The Climate Risk Group, a group of companies committed to quantifying and communicating the costs of climate change.

We’re serious about climate

Ours is a mission-driven company.

We exist to help our clients and community understand and manage unavoidable climate change, whilst demonstrating the imperative for a low carbon world.  

We see every contract as a collaboration. We are trusted by governments, NGOs, companies, banks and communities  - and while some see themselves in opposite corners - we believe it will take all actors working together to solve this challenge.

We’ve got heart



Data and information alone do not create change: data needs humanity and humanity needs ambition.

Our vision is not just to identify physical climate risks, but to also mitigate them.

Our goal is a more climate-resilient community.

Our approach is to work with you over the course of your climate risk journey.

Our clients are global

We analyse assets in over 175 countries

Adapt and thrive in a climate changing world

Our story

Global leaders in physical climate risk analysis since 2007

Backed by a team of specialists across science, engineering and software development, XDI provides best in class expertise in physical climate risk analysis to inform capital allocation, planning and risk management decisions.

Our work helps key decision makers understand the costs of unmitigated climate change at the asset, firm and investor scale.

Today, XDI is an international company with offices in Europe and Australia.

We’re always looking for dedicated climate specialists

Our data has been tested by the demands of the global market since 2007

climate risk globe scheme

The Climate Risk Engines have driven innovation in defining, pricing and responding to physical climate risk.

The Climate Risk Engines extract dynamically downscaled global and regional climate change models and combine these with global and local data sets, applying bespoke probabilistic algorithms to produce decision-ready financial and risk metrics.

Results are expressed in a range of engineering or financial metrics to inform decision-making at all scales.

Award winning technology

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.

Our hazards

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.

2023 XDI Global Hospital Infrastructure Physical Climate Risk Report

PUBLIC DATA RELEASE

How risky is your hospital?  A physical climate risk assessment of over 200,000 hospitals around the world.

XDI has analysed over 200,000 hospitals around the world for risk of damage from 6 different climate change hazards from 1990 until the end of the century. The risk arising from two different emissions scenarios (i) RCP 8.5 (around 4.3 ºC) and RCP 2.6 (1.8 ºC or under) was compared. The analysis was published ahead of the inaugural Health Day at the COP28 UN Climate Conference.

As part of the report, XDI has also released the names, location and level of risk (high, medium, low) for each individual hospital in the analysis (200,216 hospitals).  XDI is urging all governments to check for high risk hospitals in their region and conduct further analysis to understand and reduce this risk.

For access to the Individual Hospital Dataset please email [email protected]

Key findings

  • Without a rapid phase out of fossil fuels, up to 1 in 12 hospitals worldwide will be at high risk of total or partial shutdown from extreme weather events by the end of the century  - a total of 16,245 hospitals. This is almost twice as many hospitals as are currently at high risk. A residential or commercial building with this level of risk would be considered uninsurable.
  • All high risk hospitals  will require adaptation, where practical. Even with this enormous investment, relocation will be the only option for many.
  • 71% (11,512) of high risk hospitals by 2100 will be in low and middle income countries.
  • Limiting global warming to 1.8 degrees celsius with a rapid phase out of fossil fuels would halve the damage risk to hospital infrastructure compared to a high emissions scenario.
  • Today, South East Asia has the highest percentage of hospitals at high risk of damage from extreme weather events in the world. With high emissions, almost 1 in 5 hospitals (18.4%) in South East Asia will be at high risk of total or partial shutdown by the end of the century.
  • South Asia has the highest number of hospitals at risk, reflecting the high population. By 2050, a third of all the most high risk hospitals (3,357) in the world will be in South Asia if emissions are high. By 2100 this could increase to 5,894.

  • Hospitals located on coastlines and near rivers are most at risk. Today, riverine and surface water flooding dominates the risk of damage to hospitals. Towards the end of the century, coastal inundation rapidly increases (exacerbated by sea-level rise) and becomes the most significant hazard after riverine flooding by 2100.

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.
