Physical climate risk for portfolios

Physical risk, measured at the asset.

Lenders, investors and insurers must assess and disclose the physical climate risk of the assets they finance. Models give a first view; measured hazards at key sites, such as flood levels, heat and ground movement, show what the assets actually face and whether adaptation works.

  1. Insurance and finance · Physical climate risk for portfolios

    Disclosure needs evidence

    Lenders, investors and insurers must assess and disclose the physical climate risk of what they finance, and supervisors expect them to manage it. Models give a first view; measured hazards at key sites show what assets actually face and whether adaptation works.

  2. What is measured

    Water, heat and ground

    Gauges at sites and nearby watercourses measure flood levels, weather stations measure heat and extremes, and GNSS receivers on structures measure ground movement, so each key asset has its own record of the hazards it meets. Each reading carries its time and its quality flags.

    Flood gauges · Weather stations · GNSS
  3. The base node

    Measured against modelled

    The node records hazard levels and events at each site, compares them with the modelled hazard for that site and builds the event and impact record that disclosures and adaptation reviews need. Nothing is lost when a link drops; the node keeps it.

  4. Radio and links

    Around each asset

    Points around an asset reach a gateway over a low-power link and the node sends data over cellular. Measured hazards join portfolio risk tools and reach asset owners under the sharing agreement. Each link is chosen for the place, not from a catalogue.

  5. How it works

    From a flood to a repriced loan

    A warehouse rated low flood risk floods twice in a year; gauges record the depths. The lender’s risk team compares them with the model, updates the site’s risk, agrees a flood defence with the borrower, and discloses the change with evidence.

    Scope the portfolio

    The scope reads the portfolio, its modelled hazards, the most exposed and most valuable sites, and disclosure duties. Nexus Observatory Inc. returns the site selection, sensor plan, reporting and a price per site and per year. Every assumption in the scope is written down and priced.

  7. From order to operation · Survey

    Survey key sites

    Crews survey key sites with asset owners: watercourses and drains, flood marks, exposure for weather, structures for GNSS and coverage. Findings are recorded with photographs. Every finding is kept with the site record for the crews who follow. Findings shape the kit for each site before anything is built.

  8. From order to operation · Permits

    Owner agreements

    Asset owners and borrowers agree to monitoring and data sharing with lenders, investors and insurers. Every agreement is kept with the site record. Approvals are tracked site by site, so nothing waits unseen. No crew goes to site before its approvals are in place.

  9. From order to operation · Build

    Build and calibrate

    Sensors are calibrated against references, radios paired, gateways and nodes configured with each site’s modelled hazards and thresholds, enrolled with their identities and run together before they ship to the sites. Test results travel with the kit to the site.

    Open the Station Builder
  10. From order to operation · Install

    Install around assets

    Crews install gauges on watercourses and drains, weather stations and GNSS receivers on structures at each site, raise gateways and connect nodes with the asset owner’s staff. Every point is surveyed to a benchmark and photographed. The site record is updated before the crew leaves.

  11. From order to operation · Commission

    Commission against the model

    Each node proves its identity. Readings are checked against references and nearby official stations, and the first months of measured hazards are compared with the modelled hazards for each site so differences are known early. Results are signed and kept with the site record.

  12. From order to operation · Operate

    Disclose with evidence

    Risk teams see measured hazards and events across key sites, compare them with models, and use the record in disclosures, pricing and adaptation reviews. Reports for owners and funders come from the same record. Every alert and action is kept on the record.

  13. From order to operation · Maintain

    Review each year

    Each year, measured hazards are compared with models and disclosures updated, sensors checked and recalibrated, and software updated in rings. Every change is kept. Spares and procedures travel with the crews. Maintenance history stays with each site for its whole life.

  14. Data products

    For risk, disclosure and owners

    Risk teams at lenders, investors and insurers receive measured hazards by site; climate risk analysts receive model comparisons; disclosure and reporting teams receive event and impact records; asset owners and borrowers receive adaptation evidence, each tied to site and time.

    See the data products
  15. Evidence

    Disclosures on evidence

    Measured hazards support climate-related disclosures, the taxonomy’s climate risk and vulnerability assessment and supervisory expectations on climate risk. Measurements follow the WMO and hydrological guides, and every event is kept with its site. Records are open to the people who must check them.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextClimate-related disclosure standards require entities to disclose physical risks and their effects, the European taxonomy asks for a climate risk and vulnerability assessment of financed activities, and bank supervisors expect climate risks to be managed. Measured site data strengthen assessments built on models.

Hazards

  • Floods at assets models rated low risk
  • Heat that reduces output and damages equipment
  • Subsidence under buildings and infrastructure
  • Adaptation measures that cannot be shown to work
  • Disclosures that rest only on models

02What must be measured

What, where, how often, and under which rules.

Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below.
