Brief description of the data offering

The ISS ESG Climate Physical Risk solution assesses company exposure to physical risks by simulating the impact of the six most costly hazards (tropical cyclones, coastal and river floods, wildfires, heat waves, droughts) on companies’ operations and sales. The analysis is based on granular information about companies' geographical footprint, e.g., where in the world companies have production facilities and where they are generating revenue. The results show the potential financial Value at Risk of physical risks in three scenarios: historical, most likely, and worst case.

The ISS ESG physical risk solution provides metrics on both corporate and portfolio level that can be used by the investor to gain an understanding of the physical risk exposure of a portfolio or individual holding.

The key factors provided are:

  • Physical risk score per hazard and scenario: The physical risk score shows the company risk exposure. Risk exposure is defined as the overall financial impact of physical risks due to climate change on the company relative to its sector. The physical risk score expresses the change in risk between a historical scenario and a future scenario.
  • Value at Risk per hazard and scenario: In addition to the physical risk score, metrics are available showing the companies Value at Risk (VaR) as a result of physical climate risks. ISS ESG assesses the company’s VaR based on the ISS ESG proprietary Economic Value Added (EVA) model, which looks at the value of a company from an investor’s rather than an accounting perspective.
  • Management score for overall physical climate risk management: In addition to the risk exposure, each company is also given a physical climate risk management score. The management score shows if the company has taken physical climate risk into consideration in their risk management strategies.
