Climate Risk Model: what it is and how it turns climate risk into operational decisions

When climate changes faster than infrastructure, what makes the difference is not the ability to react to an event, but the ability to understand its possible consequences in advance.

If Climate Risk Assessment defines the process through which hazards, exposure and vulnerability are analysed, the Climate Risk Model is the analytical engine that makes it possible to estimate the probability of climate events, the intensity of phenomena, asset fragility, economic and functional impacts, and intervention priorities.

Its goal is not to describe risk in theoretical terms, but to make it measurable and usable in decision-making.

In this article, we clarify:

  • What a Climate Risk Model is
  • How it differs from Climate Change Models
  • What data it uses
  • How it works with probabilistic scenarios
  • How it is validated
  • How it supports CAPEX, OPEX, operational continuity and resilience

What is a Climate Risk Model?

A Climate Risk Model is an analytical model designed to estimate physical climate risk on assets, infrastructure, networks, operational processes and business systems. It combines climate, geospatial, physical, operational and economic data to transform complex information into indicators that can support decision-making.

In a Climate Risk Assessment, three fundamental dimensions are analysed: hazard, exposure and vulnerability.

The Climate Risk Model integrates these components and translates them into quantitative or semi-quantitative assessments of expected impacts.

ComponentFunction in the modelExample
HazardIdentifies the climate threatFlood
ExposureAssesses where the asset is locatedFacility near a flood-prone area
VulnerabilityMeasures the asset’s fragilityInsufficient protection
ImpactEstimates the potential effectDowntime, physical damage, cost increase

The goal is not to forecast the weather or determine with absolute certainty what will happen in the future. Rather, the model is used to estimate plausible risk scenarios and support concrete decisions on where to intervene, with what priority and with what level of investment.

The value of a model is not measured by its ability to eliminate uncertainty, but by its ability to make it readable and manageable.

In this way, climate risk stops being an isolated piece of information and becomes an element that can be integrated into business processes and adaptation strategies.

Difference between Climate Risk Models and Climate Change Models

The two tools are different but complementary, because they answer different questions:

Climate Change Model → “How is the climate changing?”

Climate Risk Model → “What impact could this change have on my assets?”

Climate Change Models

Climate Change Models simulate the evolution of the climate system over time. They analyse variables such as:

  • Temperature
  • Precipitation
  • Sea level
  • Frequency of extreme events
  • Hazard intensity
  • Future climate patterns

These models help us understand how the climate could evolve over the coming decades based on different emissions scenarios.

Climate Risk Models

Climate Risk Models add further layers of analysis to the variables of Climate Change Models, connected to the assets and activities that need to be protected:

  • Physical assets
  • Critical infrastructure
  • Local vulnerabilities
  • Operating costs
  • Economic losses
  • Service continuity
  • Decision-making priorities

Example of integration between the two models

Let us imagine an industrial facility located near a river in an area that has recorded increasingly frequent flood events over recent decades.

A Climate Change Model can show that, over the next thirty years, the intensity and frequency of extreme rainfall will increase in that territory, making flooding events more likely.

A Climate Risk Model uses this information to assess how that change could affect the facility. It can estimate the probability of flooding in production areas, potential damage to equipment, expected days of downtime and associated economic impacts, helping to define intervention priorities and adaptation investments.

Why use a Climate Risk Model for assets and infrastructure?

Two apparently similar assets can present very different levels of risk depending on their geographical location, elevation, proximity to rivers, coastlines or landslide-prone areas, construction characteristics, maintenance level, operational redundancy, dependencies on external networks and their criticality for operational continuity.

A Climate Risk Model helps understand how risk can translate into concrete consequences for assets and which interventions can reduce impacts over time.

It makes it possible to:

  • Identify the most exposed facilities
  • Estimate physical and economic impacts
  • Define intervention priorities
  • Support adaptation plans
  • Reduce downtime and unexpected costs
  • Strengthen the resilience of critical infrastructure

It is through the ability to connect climate scenarios, vulnerability and possible consequences that risk becomes a concrete variable supporting decisions.

An accurate model can establish that:

  • A railway line exposed to heat stress may require interventions on materials or new maintenance strategies.
  • An electrical substation located in an area exposed to wildfires may require protection buffers, dedicated monitoring systems and measures to reduce the vulnerability of the most exposed infrastructure.
  • A logistics hub exposed to extreme rainfall can generate delays across the entire supply chain, while a water network subject to prolonged drought periods may require investments in redundancy and alternative supply sources.

Probabilistic climate risk models

Probabilistic climate risk models are currently one of the most advanced approaches to physical risk assessment.

Unlike deterministic models, they do not return a single absolute value, but produce a distribution of possible scenarios, assigning each one a probability of occurrence.

This approach is particularly useful because climate risk inevitably contains margins of uncertainty.

This type of model can estimate:

  • Probability of an event occurring
  • Expected intensity
  • Frequency of critical threshold exceedance
  • Potential damage
  • Average economic impact

Among the most commonly used outputs are:

  • Annual Expected Loss (AEL) → example: expected average annual economic loss of €500,000
  • Risk Score → example: asset classified as high risk, equal to 8.5/10
  • Downtime Probability → example: 25% probability of operational downtime by 2050
  • Scenario 1-in-100 years → example: event with a 1% probability of occurring each year

When risk is translated into clear information, it becomes easier to assess the available options and guide decisions.

Those who manage assets and infrastructure can:

  • Compare different investment options
  • Assess trade-offs between possible interventions
  • Define acceptable risk levels
  • Establish adaptation priorities based on quantitative evidence

Input data for a Climate Risk Model

The quality of a model depends directly on the quality of the data that feeds it.

The more accurate, granular and up-to-date the data, the more reliable the estimates produced.

In Climate Risk Assessment, geospatial data already represents a fundamental component. Within a Climate Risk Model, it becomes one of the central elements for scenario simulation and impact quantification.

The main categories of input include:

Climate data

  • Historical series
  • Temperature
  • Precipitation
  • Wind
  • Drought
  • Sea level
  • Future climate scenarios

Geospatial data

  • Asset coordinates
  • Elevation
  • Land use
  • Distance from rivers or coasts
  • Hazard maps

Asset data

  • Infrastructure type
  • Age
  • Materials
  • Design standards
  • Maintenance status

Operational and economic data

  • Plant downtime costs
  • Maintenance costs
  • CAPEX
  • OPEX
  • Operational criticality

The role of data in building the model

How risk models are validated

Risk model validation is what makes it possible to distinguish a reliable result from an output that is difficult to interpret or use in decision-making.

For this reason, every Climate Risk Model must undergo continuous checks that assess its robustness, consistency and ability to represent risk realistically.

This requires analysis conducted on multiple levels:

  • Backtesting on past data
  • Control of the assumptions underlying the model
  • Verification of the quality and completeness of the datasets used
  • Sensitivity analysis with respect to the most relevant variables

Validation is not only used to measure the accuracy of simulations. It is also used to understand how the model reacts to changes in initial conditions and how robust its estimates are across different contexts.

For this reason, a model should not be assessed solely on the basis of its technical complexity. Equally important are:

  • Transparency of the methodologies used
  • Consistency of the analytical framework
  • Possibility of being updated over time
  • Ability to produce genuinely usable insights

One of the most common mistakes is relying on a numerical output without understanding the assumptions, limitations and margins of uncertainty that influence the result.

The most advanced best practices do not simply return a numerical result. Each output is accompanied by methodological explanations, confidence levels and alternative scenarios that help interpret the risk correctly and use it in decisions.

Integrating models into business processes

A Climate Risk Model creates value only when it becomes part of the decision-making process. It is not a tool to be consulted occasionally, but an information base that supports operational, strategic and investment decisions.

Integrating models into business processes helps improve activities such as:

  • Asset management
  • Predictive maintenance
  • Business continuity
  • Investment planning
  • Procurement
  • Risk management
  • Climate adaptation strategies

For this to happen, the model must be embedded in a continuous process that accompanies the entire asset management cycle.

The integration of the model into business processes develops through several key activities:

  • Collecting and updating asset information
  • Modelling risk based on climate, territorial and operational data
  • Identifying and prioritising the most critical assets
  • Defining mitigation, adaptation or protection interventions
  • Continuous monitoring and periodic updating of scenarios

The model should not be considered a one-off analysis. To continue supporting effective decisions, it must evolve together with assets, operating conditions and climate scenarios, becoming a living tool capable of accompanying the organisation over time.

From model to decision: the role of Airis

Every resilient decision begins with the ability to connect what could happen with what can be done today.

Airis is the platform developed by Eoliann to transform complex climate data into operational guidance.

By integrating climate, geospatial and asset-level data, it enables the analysis of physical risk on infrastructure and strategic assets, observing its evolution across different climate scenarios.

Through maps, indicators and high-resolution models, Airis makes it possible to:

  • Integrate climate data, territorial data and asset information into a single analytical environment
  • Model physical risk on infrastructure and networks
  • Visualise present and future scenarios down to the single-asset level
  • Identify exposure, vulnerability and intervention priorities
  • Support decisions related to CAPEX, OPEX and operational continuity
  • Plan adaptation actions based on quantitative evidence

In this way, climate risk becomes usable information to define priorities, guide investments and prepare assets and infrastructure for future conditions.

FAQ

What data is needed to build a Climate Risk Model?

A Climate Risk Model uses different categories of data, including historical and future climate data, geospatial information, physical characteristics of assets, vulnerability indicators, operating costs, CAPEX, OPEX and information on the asset’s criticality for the business or for operational continuity.

Why use probabilistic models in climate risk?

Climate risk is characterised by an intrinsic level of uncertainty. Probabilistic models make it possible to assess multiple possible scenarios, estimate probabilities of occurrence and quantify different levels of impact, providing a more robust basis for adaptation and investment decisions.

How does a Climate Risk Model support CAPEX and OPEX?

A Climate Risk Model helps identify where to invest to reduce future vulnerabilities and where to intervene to contain operating costs, extraordinary maintenance, downtime and inefficiencies. In this way, it supports more effective planning for both infrastructure investments and long-term operational management.
