Physical Climate Risk in Equity Portfolios

November 8, 2017 – 427 REPORT.  Four Twenty Seven’s Equity Risk Scores help investors identify climate risk exposure in their portfolios and design new investment strategies.  Our methodology tackles physical risk head on by identifying the locations of corporate production and retail sites around the world and their vulnerability to climate change hazards, such as sea level rise, droughts, floods and tropical storms, which pose an immediate threat to investment portfolios. This jointly published report explains our equity risk scoring methodology, features a relative risk ranking of CAC40 companies and discusses particular vulnerabilities in Asia. 

At COP23 Four Twenty Seven and Deutsche Asset Management jointly released a report featuring a new approach to climate risk management in equity portfolios. Measuring Physical Climate Risk in Equity Portfolios showcases Four Twenty Seven’s Equity Risk Scoring methodology, which identifies hotspots in investment portfolios by assessing the geographic exposure of publicly-traded companies to climate change.

This comprehensive, data-driven scoring effort culminates in a composite physical risk score that allows for comparison and benchmarking of equities and indices.  This integrated measure provides a point of entry to understand and address climate risk, engage with corporations and identify risk mitigation strategies. “This report is a major step forward to addressing a serious and growing risk that investors face. To keep advancing our efforts, we believe the investment industry needs to champion the disclosure of once-in-a-lifetime climate risks by companies so we can assess these risks even more accurately going forward,” said Nicolas Moreau, Head of Deutsche Asset Management.
