Climate Scenario Lab

Turn climate scenarios into decisions your business can use.

A focused engagement that translates selected physical and transition scenarios into transparent, decision-relevant implications for underwriting, claims, investments, profitability or capital.

When the Lab helps

Start with the decision—not with a library of scenarios.

The Lab is designed for a defined management question where climate uncertainty needs to be translated into a financial or actuarial view.

01

Portfolio resilience

Identify concentrations and compare how selected pathways may affect portfolio performance.

02

Underwriting and pricing

Test how material climate drivers could influence exposure, claims or pricing assumptions.

03

ORSA, SST and ERM

Develop a traceable quantitative view that can inform risk assessment and management discussion.

04

Strategy and investment

Compare financial sensitivities and clarify the actions that deserve further analysis.

Suggested scope

A controlled prototype with a clear line of sight to action.

Scope is agreed around one priority decision, selected scenarios and a manageable portfolio, business unit or risk type. This keeps the analysis proportionate and makes assumptions easier to challenge.

A typical Lab focuses on:

One decision question, one or two portfolios or functions, and a limited set of relevant pathways and time horizons.

  1. 01

    Frame

    Define the decision, material exposures, metrics, boundaries and success criteria.

  2. 02

    Select

    Choose relevant pathways, variables, time horizons and reference data.

  3. 03

    Translate

    Map scenario variables to actuarial, financial or operational risk drivers.

  4. 04

    Quantify

    Build a transparent prototype and test impacts, sensitivities and limitations.

  5. 05

    Decide

    Review findings with management and agree priorities for refinement or integration.

What you receive

Enough structure to support a decision—and a defensible next step.

01

Scenario scope note

Decision question, selected pathways, time horizons, metrics and analytical boundaries.

02

Translation framework

A documented link from climate variables to business and financial risk drivers.

03

Prototype analysis

Transparent calculations, scenario comparisons and sensitivity tests at the agreed level.

04

Assumption register

Key assumptions, data limitations, expert judgements and areas requiring validation.

05

Management readout

A concise presentation of findings, implications and potential management responses.

06

Next-step roadmap

Priorities for refinement, governance, integration, additional data or model development.

A proportionate engagement

Clear inputs and clear boundaries.

Typical client inputs

  • Portfolio or exposure data at an agreed level of detail
  • Existing risk assessments, models and relevant assumptions
  • Materiality criteria, risk appetite and decision context
  • Access to relevant business, risk and actuarial stakeholders

Normally outside the Lab

  • Development of new climate-science projections
  • A full production model or enterprise-wide implementation
  • Independent assurance or formal model validation
  • Legal opinions or certification of regulatory compliance

Start with the management question

What scenario decision are you trying to make?

A short initial discussion will help determine whether a focused Scenario Lab is the appropriate next step and how it should be scoped.
