Since 2006, decision makers have come to our team to understand the physical impacts of climate change to their business operations.

XDI’s analysis is underpinned by the Climate Risk Engines, developed through extensive commercial engagement with industry and government.  From the outset, insights provided by the Climate Risk Engines have steered the conversation around climate change adaptation for a committed group of professionals who understood the need to find language and processes to incorporate climate risk and adaptation into decision making.

As the sophistication and power of the analysis evolved, a new understanding of more complex risks to larger businesses and governments began to emerge. Beyond individual assets, there was a need to analyse climate risk at an ecosystem level; to see the impacts of failures to power, water and transport infrastructure to people and organisations that depend on them.

In 2011 the XDI vision was born; to make possible a systems analysis of how climate risk affects not just one organisation but all of its upstream and downstream interdependencies. This is XDI, The Cross Dependency Initiative. A whole system vision of climate impacts that accounts for all physical risks, powered by a world class benchmark of computational analysis.

XDI’s award winning analysis supports decision making in finance, business and governments world-wide, with detailed, investment ready information for physical climate risk. With its core technology already tried and tested in the market, XDI has been perfectly placed to meet the rapid growth in demand for climate risk analysis since the release of the TCFD Recommendations working with clients world wide, providing sector specific customisable solutions.

XDI’s range of third party, company intelligence products provide institutional investors with high level insights on extreme weather and climate change risks to a single company or group of companies. Aggregated information gives investors an understanding of the investee’s physical climate risk profile in simple financial metrics, based on the assets a company owns or leases around the world. 

Global leaders in Physical Climate Risk Analysis since 2006

XDI strives for the highest quality in the information that companies and communities use to make decisions. Globally, XDI analysis ranks the highest for hazards covered, geographical reach, and capacity for analysis of large numbers of assets. It is the most rigorous analysis available and, with sophisticated online data visualisation in XDI Platform, the most flexible.

Our People

XDI Management Team


Rohan Hamden

Advanced MBA (International Finance and Management), B.Sc (Biotechnology) B.AppSc. (Cons & Park Mgmt.)


Rohan is the CEO of XDI: The Cross Dependency Initiative, which provides infrastructure risk assurance services based on climate change science, infrastructure engineering and advanced statistical methodsRohan began his career as a fire fighter. After nearly 15 years in government, his last role was as the Director of the Climate Adaptation Program for South Australia. He designed and led the implementation of the States multi-award winning climate change adaptation program. This program has seen a transformation in how communities and industries work together to adapt to climate change. Rohan has advised various state and national governments on their climate adaptation programs in Australia, Canada, USA and the UK. In 2017 he co-founded XDI with a vision of mainstreaming climate information into infrastructure and financial decision making. 

Ruth Tedder

Zafi Bachar brings 20 years of experience to his Project Manager role with XDI. He was one of the founders of the multi-award winning Green Steps program at the Monash Sustainability Institute, and later worked for Origin Energy, ICLEI, AECOM, and multiple municipalities in Victoria and South Australia. More recently, Zafi worked with the South Australian State Government Department for Environment and Water facilitating innovative urban adaptation partnerships.

Michael Bojko


Senior Analyst

Michael leads the team in scientific research and the detailing of asset data with climate hazards, exposure and vulnerability. He specializes in land use planning data in  high growth corridors for XDI land use planning analysis. Recent projects he has lead consider climate impacts on human health, liveability, the environment and infrastructure, and assessing the effectiveness of different adaptation strategies to reduce these impacts.

Anastasia Martinez

BEnvSc, BSustEnv(Hons)

Senior Analyst/Project Manager

Anastasia works closely with a wide range of organisations to marry XDI technology with the complex data and analysis requirements of clients.  She specialises in water sensitive urban design, cost-benefit analysis and urban heat microclimate modelling.  Anastasia brings to XDI her expertise on the impacts of green infrastructure and tree canopies to urban heat sinks and human liveability.  

Climate Risk Engines Team

Karl Mallon 2

Dr. Karl Mallon 

B.Sc. (Physics), Ph.D. Mech. Engineering.  University of Melbourne

Director, Science and Systems

Karl is a founding board member of The Climate Bonds Initiative (London), Co-Director of XDI and Director of Science and Systems at Climate Risk Pty Ltd.  In his role at Climate Risk, he developed the Climate Risk Engines that underpin XDI’s analysis. Since 2006, Karl’s work has focussed on developing systems to understand the complex play of climate change variables that impact an organisation’s physical assets, human resources and management processes. From 2011, Karl and his technical team have been engaged in developing qualitative and quantitative processes that capture this complex challenge. A major focus has been the integration of hazard, engineering and financial data into high-speed cloud computing software to provide decision support systems for governments and corporations.

Karl has worked in climate change mitigation, policy and technical analysis since 1991 in Europe and Australia, and specialised on climate adaptation since 2005. His interests vary widely, from working on policy issues with international government and non-government organisations; financial issues in the insurance and institutional investment sectors; and the risks to infrastructure, local government and residential assets.  Karl is editor and co-author of ‘Renewable Energy Policy and Politics: A Handbook for Decision Making’ published by Earthscan (London) and a contribution author for ‘Practical Adaptation Studies’, published by Wiley.
