Learn more about EarthScan Ratings and how they are calculated
EarthScan™ Ratings provide globally comparable estimates of climate hazard probability and direct physical damage to built assets.
Built on a globally standardised framework, EarthScan Ratings summarise the latest climate science, data and models to give decision-makers a quick and clear indication of an asset’s climate-related risk.
Assets are the individual building blocks of the EarthScan Ratings framework. By starting at the asset-level - providing a shared, comparable and standardised view of climate risk across different geographies, time horizons and hazard types - Ratings deliver climate intelligence across multiple scales, from individual assets to portfolios, companies and financial securities.
EarthScan Ratings are available across six individual hazard risk categories. Risk categories describe distinct types of climate hazard or peril with the potential to cause direct damage or disruption to built assets, such as flooding or wildfire. For each risk category, Ratings are calculated based on a suite of climate hazard exposure metrics, which are generated by applying statistical modelling approaches to exposure metrics to describe how climate hazard probabilities change for a given location over time and across future emissions scenarios.
Currently, Ratings are available for the following climate hazards: heat stress, extreme precipitation, extreme wind, drought, coastal and riverine flooding and wildfire. Ratings for heat stress, extreme precipitation, and drought (hazards that predominantly cause disruption to operations) are calculated using hazard probability metrics.
Ratings for hazards that cause the greatest amount of direct physical damage to built assets, extreme wind and flooding, are calculated using hazard probability and Climate Value-At-Risk (CVaR) metrics.
