The ClimEmpower risk assessment workflow treats Hazard (H),
Exposure (E) and Vulnerability (V) as distinct components.
After the input variables are processed on a common scale, the final risk score is calculated as
R = H Γ E Γ V.

Hazard
A climate-related event or process with the potential to cause harm.
Exposure
The presence of people, assets or ecosystems in areas affected by the hazard.
Vulnerability
The susceptibility of exposed elements to suffer harm or loss.
Risk Score
With H, E and V standardised to 1β10, multiplication produces a 1β1000 risk score.
MODULE 03 // COMPONENT CONSTRUCTION
Build Each Component, Then Multiply
Where several variables make up one component, the ClimEmpower AIT methodology uses transparent variable-level weighting. Equal weighting is used where specified, while asset-specific indicators are kept separate to avoid diluting risk through inappropriate averaging.
1. Standardise inputs
Convert variables to a comparable scoring scale where required and document whether higher or lower raw values represent higher risk.
2. Construct H, E and V
Aggregate only variables belonging to the same component and risk profile. Use the hazard- and asset-specific methodology shown on each hazard page.
3. Calculate risk
R = H Γ E Γ V
For 1β10 component scores, the resulting ClimEmpower risk index ranges from 1 to 1000.
Local data can replace or refine broader datasets when suitable. Assumptions, spatial-resolution trade-offs, temporal limitations and uncertainty should be documented explicitly.
MODULE 04 // ASSET-SPECIFIC RISK
Hazards and Assets Covered
ClimEmpower separates risk profiles by the asset or sector being assessed instead of averaging unlike exposure layers into one generic map.

CLIMATE HAZARD RISK ASSESSMENT
Drought
Population and Agriculture
ClimEmpower assesses drought risk separately for population and agriculture. The hazard component uses SPI-12 and NDMI, while exposure and vulnerability indicators are selected for the respective risk profile.

Within ClimEmpower, heat-induced risk focuses on people. Heatwave definitions are region-specific; the adapted AIT implementation also uses Land Surface Temperature and regional temperature-extreme metrics to spatialise heat hazard.

Region-specificNo single universal heatwave threshold is applied across all pilot regions
Wildfire hazard combines the Fire Weather Index with burnable vegetation. Burnable vegetation is explicitly treated as a hazard factor, while exposure and vulnerability are constructed separately for population, biodiversity, infrastructure, tourism and agriculture.

The ClimEmpower flood methodology assesses flood impacts for buildings, population and critical infrastructure using asset-specific exposure and vulnerability information where available.

Because risk is an equation, increasing adaptive capacity lowers vulnerability and generates a new, lower risk score after intervention.
