Our Theory of Change

We believe that when people can quantify the costs of climate change, it empowers them to plan for resilience, to innovate, and to change the way things are done.
We strive to build the most powerful and accurate risk engines possible using the best data and technology available.


We build from the ground up using bespoke code, running on specially configured banks of high-speed servers. We use engineering methods focused on the physical mechanisms that undermine the ability of an asset, system or person to function. We use statistical and probabilistic methods to compute how extreme weather and climate change will cause such harm going forward.

Accuracy within

Risk is the science of uncertainty. And managing uncertainty is a bedrock of climate science. Our job is to build a bridge between the two. We interrogate models of the global and regional climate at large spatial scales, and use those to adjust weather and hazards data that may be highly localised, where differences of just metres can be the difference between safety and damage.


We are one of the biggest and most tenacious climate adaptation teams in the world. Our skills span applied science, engineering, finance and public policy. We pride ourselves on cutting edge work and the ability to work with many sectors - from insurers and banks, to utilities and governments and environment groups and community service organisations. Our record on innovation and outcomes speaks for itself.

Our Latest Engine: CRE Paragon

Our latest computing solution - CRE Paragon - boasts more than 872 CPU cores using a cluster of 12 high speed AWS servers.
It'™s named after the Intel's Massively Parallel Supercomputer of the same name that that ran in the 1990s. By spinning up parallel instances on CRE Paragon we can diagnose current and future risks to portfolios exceeding 1 million assets. CRE Paragon was first used to compute the climate and extreme weather risks to the 1.5 million mortgages held by the Commonwealth Bank. CRE Paragon'™s current record is 14.7m properties in a single run.

Climate Risk Est 2005

A lot has happened over the last 15 years. Climate Risk was established in 2005 with the specific mission to compute the costs of climate change risks to society, so that the costs of inaction on emissions could be understood. Registered in Sydney, Australia the company quickly delivered precedent setting work with the global insurers Zurich that highlighted the need for forward looking actuarial analytics. A project on the role of telecommunications companies commissioned by Telstra '˜Toward a high Bandwidth Low Carbon Future'™ was presented in Davos and formed the basis of two UN conferences.

    AdaptWater, NCCARF Award

    Working with a consortium of water utilities and the Australia Government, Climate Risk and Sydney Water developed software to undertake cost benefit analysis and adaptation planning across large numbers of highly engineered assets... The system went through international peer review by scientists, engineers and financial analyst and went on to win a national award from the climate science community. AdaptWater has been used continually since its launch, informing adaptation of assets worth up to a quarter of a billion dollars.

    AdaptInfrastructure & AdaptRoads

    The Climate Risk Engines were now able to process an ever expanding range of fixed and linear assets; water, wastewater, power, roads, rails and telecomm's. New commodities were added like data flows and customer disruptions... AdaptInfrastructure was even expanded to look at government owned housing, requiring a major increase in processing capability to 100,000 assets. The AdaptRoads project identified the risks of road surfaces being burned out by wildfires, or pot-holed by flooding. The system also expanded to include ‘traffic’ as a reporting KPI. Processing capacity expanded from handling hundreds of assets to 1,000s.

    Climate Valuation

    To support the democratisation of climate change risk analysis, the Climate Risk Engines were harnessed to analyse residential property at low costs for use by home buyers and the real estate industry. Uptake has peaked at over 4,000 report downloads per day!

    XDI Launches

    The Climate Risk Engines now made the jump to treating sectors separately to providing comparative analysis within a single platform. This enabled benchmarking sectors against one another using the same scenarios. It provided the ability to analyse cross-dependent risks, which could ripple through a supply chain and whilst also finding opportunities for cost-sharing and collaborative adaptation.

    World EasyXDI, BTA Award

    XDI Sydney Project wins the Better Together Award. Supporting XDI’s global ambition’s Climate Risk Engines have provided the heavy lift behind www.EasyXDI.com which aims to analyse any infrastructure, at any time this century, anywhere on the planet... To access data on changes to the climate is relatively straight forward in most places, but to compute physical and financial risks based on weather data, forests, soils, coasts, elevations and flood maps is perhaps the most ambitious project of its type ever undertaken in private sector adaptation research.
