What this category does
Climate risk and catastrophe modeling providers estimate how hazards such as floods, wildfires, hurricanes and extreme heat could affect a portfolio, a property or a business. Their output is usually a risk score, an expected loss or a set of scenarios for a location, and it feeds underwriting, lending, disclosure and capital planning.
These products combine hazard models, exposure data and assumptions about how buildings and operations respond. The result depends on all three. Two providers can disagree on the same address because they model the hazard at different resolutions or assume different vulnerability for the same building.
Expect the sales process to be consultative. Vendors in this field often tailor outputs to a buyer's portfolio, which is useful, but it also means a demonstration may show a polished example that differs from what you receive.
How buyers evaluate
Buyers commonly run a pilot on a sample of their own assets, then compare results across providers and against losses they have actually seen. Where a provider's output differs from the others, a good vendor can explain why. A pilot of one to three months is typical, and the review often involves risk, data and compliance teams, not only the buyer who found the vendor.
RFP criteria include the hazards covered, the geographic resolution, the climate scenarios and time horizons offered, whether results are explained or only scored, the audit trail for regulators, delivery by API or in bulk, and the licensing terms for using results in client reports.
Ask for documentation of the method. Regulators and auditors increasingly expect a buyer to describe where a risk number came from, so a score without an explanation is a liability.
Buyers sometimes treat climate risk numbers as more precise than they are. Projections look decades ahead and depend on scenario assumptions, so a sensible vendor presents ranges and states its uncertainty. Be wary of any provider that gives a single figure for a distant year without explaining what it assumes.
Questions to ask a vendor
- Which hazards do you model, and which do you not model at all?
- At what resolution, and how do you treat locations near a boundary?
- Which climate scenarios and time horizons are available?
- How was the model validated, and is the validation documented?
- Can I see the inputs behind a single result for an asset I know?
- May I include your outputs in reports that go to clients or regulators?
- How often are models updated, and are past results restated when they change?
How to read the capability facts
Profiles list forecast types such as climate projections and historical data, the parameters covered, the regions served and the industries a vendor works with. Use the industries field to find vendors with experience in insurance, finance or real assets, since their outputs are shaped for those users.
The facts show scope and not method. For this category, the method is the product, so treat a profile as a way to build a shortlist and ask for the technical documentation next.
Consider who will use the output, too. A risk team may want the full detail, while a client-facing team wants a short summary it can defend. Ask whether the vendor supplies both, and whether the summary can be traced to the detail behind it.
Where to go next
Build a shortlist by hazard and region, then ask each vendor for method documentation and a pilot on a sample of your assets.
