Indexing Methodology

We can now translate the expected damage for each feature calculated from the Resilience-adjusted Risk Framework into a set of scores that capture both the shifting intensity of risk from the current period to 2100 as well as the adaptation capacity of each location, resulting in an overall "ground truth" resilience profile.
Currently, there are six hazard scores in the index. These scores work like risk ratings based on a score card that scales with the intensity of the hazard, giving the absolute risk exposure of a location for one type of risk at any given scenario and time period on a scale of 0 - 100. Please refer to the score card above for how the scores and categories are assigned for each index. You may also download a PDF version here.
The category breaks are based on the Mean Damage Ratio (MDR) for the respective features. The higher the risk scores and category assigned for each feature, the higher the expected mean damage ratio caused by the contributing feature, and the more advanced the mitigation strategies required.
The overall scores, i.e. the Overall Physical Climate Risk Score and Overall Resilience-adjusted Risk Score, are global percentile scores that measures the overall risk profile of a location in comparison to other locations, allowing users to compare the overall risk profile of one location against another.
The platform offers two set of scores: the Physical Risk Scores, where the hazard exposure is scored on a scale of 0 to 100, and the Resilience-adjusted Risk Score, where local adaptation features, and societal resilience are applied to reduce the Physical Risk Scores where applicable. The image below shows the visualization of the dashboard for one sample location.
On the left panel, the individual scores indicate that this location has a high Overall Physical Climate Risk score of 61/100, with particularly high risk in Heat Stress and moderate risk in Inland Flooding and Coastal Flooding.
On the right panel, we see that the overall Resilience-adjusted Risk is 14 points lower at 47/100 due to the effectiveness of the location's adaptation measures in reducing the corresponding risks. We see that both Inland Flooding and Coastal Flooding have been reduced from 40 to 30, which is also one category lower from before (Medium to Low).
Looking at the score card for coastal flooding, this means that even though the location is exposed to the coastal flooding with an 1000-year inundation level between 23 to 35cm, the effective risk after adjusting for local adaptation is lowered to 16 - 23 cm which would lead to lower expected damage and thus require less extensive on-site mitigation strategies.
