EDHEC Climate Institute Introduces Probabilistic Climate Scenario Framework to Aid Financial Planning

(...) As climate change increasingly drives financial risk assessments and regulatory scrutiny, a persistent issue has remained unaddressed: the lack of probabilistic insight in climate scenario modeling. In response, the EDHEC Climate Institute has released a new study proposing a structured framework to quantify the likelihood of future climate outcomes—aiming to improve how financial institutions incorporate climate data into their risk models.

The white paper, titled “How to Assign Probabilities to Climate Scenarios”, outlines a groundbreaking methodology that integrates real-world policy trends and economic indicators to assign probabilities to different global temperature pathways. This probabilistic overlay enhances traditional scenario narratives, offering greater precision for tasks such as asset valuation, stress testing, and long-term investment strategy.

The analysis draws from a comprehensive dataset of over 5,900 Social Cost of Carbon (SCC) estimates across 207 scholarly studies. It employs two distinct techniques: an expert-elicitation model reflecting the gap between climate policy recommendations and their real-world implementation, and a maximum-entropy model that relies solely on observed data while minimizing assumptions.
