Physical Climate Risk Scoring

Deriving asset- and portfolio-level physical climate risk scores from satellite-observed hazard data — flood extent, heat stress, wildfire burn scars, drought indices — at sovereign scale.

Every bank, insurer, pension fund and infrastructure ministry now faces mandatory disclosure of physical climate risk under TCFD, ISSB and emerging national frameworks. The problem is that commercial risk scores are black boxes produced by foreign vendors using proprietary models calibrated on datasets you cannot audit. When a regulator or a bond market asks your sovereign wealth fund to prove its methodology, 'we licensed a score' is not an answer.

Satellite observation is the only way to measure physical hazard at the asset level, globally and repeatedly. A constellation combining multispectral optical imagery, SAR for flood and subsidence detection, and thermal infrared for heat-island and drought mapping can produce annual hazard layers at 10–30 m resolution across the entire national territory. Those layers feed a scoring model — flood return periods, wildfire proximity, extreme-heat days, coastal inundation probability — that can be re-run on demand as climate projections or exposure inventories change.

A sovereign physical climate risk platform does three things a rented score cannot: it lets the central bank set the hazard definitions that match national building codes and land-use law; it lets the treasury stress-test the sovereign balance sheet against classified asset registers; and it gives regulators the raw imagery to verify any institution's self-reported score. That is the difference between compliance theatre and genuine financial stability intelligence.

What matters

ISSB S2 and TCFD require disclosure of methodology, not just a score — sovereign observation chains are auditable end-to-end in a way that licensed third-party scores are not.
Flood return-period maps derived from SAR change-detection are 3–5× more spatially precise than reanalysis-only models, directly affecting capital adequacy calculations for exposed infrastructure.
Wildfire burn-scar and drought-index products derived from national satellite imagery can be withheld from foreign counterparts during sensitive sovereign debt restructuring negotiations.
Re-calibrating hazard layers after an extreme event takes hours on a sovereign pipeline; waiting for a vendor update can take weeks, creating a regulatory reporting gap.

Sovereignty score: 8/10 — A nation that relies on foreign vendors for its physical climate risk scores surrenders control over the methodologies that will determine capital flows, insurance pricing and regulatory legitimacy across its entire economy.

Foreign commercial risk-score providers operate under their own governments' export and data-sharing regulations — a vendor can be compelled to alter, withhold or reprioritise hazard products during bilateral tensions, directly distorting a nation's financial stability assessments.
Mandatory climate disclosure regimes (TCFD, ISSB S2, EU CSRD) require auditable methodology chains; a licensed score cannot satisfy a regulator demanding primary evidence, creating legal exposure for both financial institutions and the prudential authority.
Sovereign asset registers — power grids, defence installations, state-owned enterprises — cannot be submitted to a foreign SaaS platform for risk scoring without breaching national security classification requirements, making a domestic pipeline non-negotiable for whole-of-government stress testing.
Climate hazard data is increasingly a geopolitical instrument: controlling the national flood and drought record gives the sovereign treasury negotiating leverage in climate finance, loss-and-damage discussions and catastrophe-bond structuring that no rented score can provide.

Reference architecture

Payload: Multispectral optical imager (10 bands, 400–2500 nm, 10 m GSD) for burn-scar, drought and vegetation stress; thermal infrared channel (8–12 µm, 100 m GSD) for land surface temperature and heat-stress mapping; X-band SAR (3 m spotlight, 30 km swath) for flood extent and subsidence detection via InSAR
Bus class: ESPA-class microsat, 150–200 kg, 600 W payload power; optical and SAR payloads can be split across two complementary bus types within the same programme to reduce schedule risk
Orbit: Sun-synchronous LEO at 520–560 km; 12-satellite walker constellation providing 2–3 day revisit at equator and daily revisit at mid-latitudes; local time of descending node 10:30 for optical consistency with Sentinel-2
Ground segment: 3-station national network (X-band downlink, S-band TT&C) co-located with existing meteorological ground infrastructure; ESA/KSAT backup downlink agreement for contingency; national HPC centre for SAR InSAR processing
