EDHEC releases ratings to track the impact of climate on infrastructure assets

The founder and CEO of a climate rating firm founded at the French business school EDHEC, has said that it is the first company to have estimated financial losses for thousands infrastructure assets under different climate change scenarios.

It is becoming increasingly important to understand the costs of climate changes, as political pressures are leading some countries (including the United States) to reduce environmental policies and climate targets.

"We observed a critical disconnect." Climate risks are increasing, but most financial decisions ignore them or dismiss them as non-financial concerns, said EDHEC CEO Remy Estran.

Scientific Climate Ratings will cover around 6,000 assets initially, before expanding to more than 5,000 listed stocks in 2026, according to him.

While many companies have attempted to assess their exposure to physical risks from climate change such as wildfires and floods, the majority of assessments on the possible effect of infrastructure are at a high level.

It is crucial to understand the financial risks embedded in the system, as billions of dollars have been invested in infrastructure, such as airports, ports and utilities that are susceptible to extreme weather.

The ratings, which are based on a global EDHEC dataset tracking assets in great detail, will provide granular information to improve the financial risk assessment of investors and businesses.

Two stages are included in the methodology: A Potential Exposure Ratings will assess how exposed an asset is to future climate risk under current government policies. A Climate Risk Effective Ratings will estimate the financial impact of various climate scenarios between 2035 and 2050, using probability analysis. This includes the likely dollar impact in terms of the net asset value.

Estran-Fraioli stated that out of 6,050 assets, 1,088 will experience losses of 24% or more by 2035 if nothing is done. This figure could rise to 50% by 2050.

He added that the assets with the highest rating (A or B) only account for 2% of expected losses, while the assets with the lowest rating (F and G) are responsible for almost 50%. (Reporting and editing by Emelia Sithole Matarise; Reporting by Simon Jessop)
