The April 27 version introduces improved risk score coverage and updates the scoring methodology to 2023.2.

Updated Scoring Methodology 2023.2

This Climate on Demand release updates the scoring methodology to 2023.2.The updated methodology allows you to run scenario analyses using RCP8.5 and RCP4.5 to the end of the century.

For more information about the methodology, see Real Assets Physical Climate Risk & Corporate Facility Operations Risk Methodology 2023.2. The scoring methodology 2021.1 is no longer supported.

Scenario Analysis

This Climate on Demand update supports scenario analyses for RCP8.5 and the adds support for RCP4.5 for Floods, Heat Stress, and Wildfires for forward-looking decades out to 2100. It updates Risk Scores to reflect climate change outcomes from two climate emissions pathways or scenarios and time horizons out to 2100.

This update is calibrated for scenario analysis use cases, with a particular emphasis on inter-comparability and consistency between all time horizons and both RCPs covered. Due to the high level of extreme outcomes at the end of the century now embedded within the scoring methodology’s Investible Scoring Universe, scores at earlier time horizons, such as 2030-2040, tend to be much lower than in previous releases, particularly for Heat Stress. Risk level designations also follow this pattern.

Climate Models

For this methodology update, Climate on Demand has leveraged the best-in-class climate models used by the IPCC, specifically Coupled Model Intercomparison Project version 6 models (CMIP6), down-scaled by NASA. This update to CMIP6 applies to Floods, Heat Stress, and Wildfires.
