01In brief

The short answer.

The Climate and Nature Financial Risk methods page sets out the methods the platform relies on, among them climate and atmospheric science, ecology and biodiversity science, and scenario design and stress testing, with their assumptions, validation and limits. Each analysis lists its assumptions and data, reports ranges and confidence beside central estimates, is checked against observations or other models, and states what it cannot show.

Canvas · draft to published versionDesign, not a record
Analysis and uncertainty: systematic evidence synthesisA question is framed with its owner and a protocol registered; records are searched, screened and checked for eligibility by two reviewers; data are extracted, synthesised and graded for certainty before a brief is written. Design of the process, not a record of a run.

03Spatial finance

Assets on the grid, and the portfolio they make.

Where a portfolio's assets sit, and how much of its value is most exposed. Hypothetical assets, not an assessment.

Sixteen assets at real towns, and the share of portfolio value in the most exposed places.Hypothetical assets and design scores, not advice.
05Methods

Top-down and bottom-up climate risk.

06Spatial statistics

Hazard at the right resolution.

Asset-level work depends on hazard resolution and on joining correctly: a coarse flood grid can misclassify assets near river channels. Methods at GCRI spatial statistics; measurement gaps at model and measurement gaps.

07Uncertainty

How uncertainty is reported.

  1. 01

    State assumptions

    Each analysis lists its assumptions and the data it depends on.

  2. 02

    Quantify where possible

    Ranges and confidence are reported alongside central estimates.

  3. 03

    Validate and compare

    Models are checked against observations and, where possible, against other models.

  4. 04

    Publish limits

    What an analysis cannot show is stated beside what it can.

08Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Uncertainty quantificationCharacterising and propagating the uncertainties in a model to state confidence in its outputs.
Sensitivity analysisRepeating an analysis under different assumptions to show how much the result depends on them.
Model validationIndependent testing that a model performs as intended and is fit for a stated use.
Climate and atmospheric scienceClimate science studies the physical processes that govern the atmosphere, oceans, cryosphere and land surface over seasons to centuries.
