Frequently Asked Questions
What does TransZero do?
The TransZero web platform provides an interactive dashboard for subscribers to upload their property assets, model the risk and then translate their climate risk findings into practical decision-useful risk metrics.
What sectors does TransZero support?
The TransZero platform supports a very wide variety of business interests and alternative use cases for physcial climate risk. Key sectors include real estate, retail, asset management, banking, insurance and international development. Typical clients include sustainability officers, risk managers, underwriters and investors. .
How is Transzero different from traditional ESG dashboards or climate scenario reporting tools?
TransZero is an asset-level risk and resilience modelling platform which focuses on providing high resolution physical risk modelling and damage assessments for 10 x different climate hazards globally (down to 5m x 5m grid resolution). This is in contrast to other ESG tools and dashboards which provide only aggregated country or regional sector scores.
Unlike other climate scoring tools, TransZero quantifies the losses of climate risk by associating the hazard intensity of particular climate risks to the likely financial damage likely to be experienced on an annual basis.

Which climate hazards (“perils”) do you model?
We model 10 core physical climate perils. This includes both fast-onset (e.g. windstorms) and slow-onset (e.g. sea level rise) perils:
River flood
Surface flood
Sea Level Rise
Extreme heat
Drought
Extreme hail
Wildfire
Landslide
Windstorm
Subsidence
At what resolution do you model risk?
We can model any location in the world. Using either a user-defined latitude/longitude or a property level address, our geocoding engine models climate risks down to individual asset-level resolution. Model resolution varies but for the Europe, US, and Australia our hazard modelling goes down to 5m x 5m grid resolution.
Which climate scenarios do you use?
We model both the current day probability of climate risk (as of 2026) based on historical weather experienced to date as well as a range of alternative future climate pathways based on the recommended emission scenarios of the International Panel Of Climate Change (IPCC). These globally recognised Shared Socioeconomic Pathways (SSPs) incorporate the complexity of early and late efforts to reduced Greenhouse Gas (GHG) emissions resulting in different global warming outcomes.
TransZero models how these different climate perils will alter the risk to property assets through damage frequency and severity at decadal intervals from 2026 through to 2100.
Are there uncertainties in climate risk modelling?
While climate science has made ground-breaking advances in the physical risk modelling, climate systems are chaotic and highly uncertain. TransZero aims to reduce uncertainty through use of:
Ensemble modelling – use multiple climate models (GCM) rather than a single model.
Alternative SSPs / RCPs climate scenarios – TransZero offers a range of climate scenarios rather than a single-path prediction.
Transparent methodology – technical guides and documentation in TransZero help provide clear messaging around model sources and methodologies.
Do you support firms in their climate-related disclosures requirements?
Yes. Our modelling supports the physical risk component of all major climate-related disclosure reporting. See here for more detail. This includes:
TCFD-aligned frameworks (UK)
Bank Of England (Prudential Regulation Authority) and Solvency II (UK)
Securities and Exchange Commission (US)
ISSB climate standards (Global)
CSRD / ESRS requirements (Europe)
We provide quantified physical risk quantification, data, charts, maps, insights, and scenario analysis to support both internal and external regulatory reporting for climate disclosures.

Do you model transition risk as well?
Our core expertise is physical climate risk and resilience. However, we can integrate outputs into broader climate risk frameworks that include transition risk considerations such as policy change, carbon pricing and sector exposure where required.
How do you translate climate hazards into financial risk?
We combine the climate hazard intensity and probability at an individual location (or portfolio of locations) with the respective property/asset valuation and engineered fragility curve to estimate site level damages. TransZero’s expertise in geocoding, hazard probability, asset vulnerability and mitigation impacts are key to providing accurate risk and financial loss scoring. This helps clients identify material risk concentrations, supporting capital planning and impairment analysis as well as estimate the ROI of adaptation measures on their portfolio.
How is Transzero different from traditional ESG dashboards or climate scenario reporting tools?
Yes. Clients can upload their primary assets as well as their first and second-tier suppliers. The platform models these and makes connections allow users to quantify how climate risk can compound across different global supply chains. This allows companies to build redundancy measures and build resilience into their globalised business models.
Can TransZero model supply chain climate risk?
What if we don’t have precise supplier location data?
That’s fine. TransZero have a range of geocoding engines that can take precise or approximate address information and convert this into precise latitude / longitude location information. TransZero also provides a geocoding report to highlight the success of geocoding large property/asset portfolios.
How do you support resilience and adaptation planning?
Beyond risk identification, we help clients:
Prioritise high-risk assets
Compare adaptation investment options
Stress-test capital expenditure plans
Identify geographic diversification opportunities
Develop phased resilience roadmaps
How is Transzero different from traditional ESG dashboards or climate scenario reporting tools?
This is entirely dependent on your company’s risk profile, internal/external reporting requirements and how your property portfolio may have changed within a time-period.
However, the recent trends and recommendations in climate risk management and disclosure reporting (SS5/25) are moving towards climate risk as an ongoing process and strategy (not a periodic box ticking exercise). This is why we developed TransZero as a subscription service to help facilitate continual assessment and modelling for companies.
How often should climate risk modelling be updated?
Can your models integrate with our internal risk systems?
Yes. Climate risk outputs can be delivered via:
API integration – seamless integration of results and climate data through use of TransZero’s Application Programming Interface.
Application downloads of data – export data, charts, map images, and plain-language summarises from the TransZero application into standard office formats for reporting or workflow integration. We design delivery to align with existing risk and reporting workflows.
How do you validate your modelling?
Validating climate risk models is arguably the most important factor in model development. This includes:
Benchmarking climate risk models and data against hazard and financial loss data relating to historical events
Third-party hazard data comparisons
Research literature reviews of similar studies.
Sensitivity testing
Alignment with peer methodologies
