Abstract

This paper investigates the relationship between ESG scores and Default Probability (DP) for European firms in the STOXX Europe 600 index. We model this relationship using the Altman Z-Score and Ohlson O-Score as proxies for DP in regression analysis, while controlling for leverage, volatility, and size. The findings of this study show that higher ESG scores are associated with a higher DP for the Altman Z-Score, but with a lower DP when using the Ohlson O-Score. This discordant outcome highlights the sensitivity of results to the choice of DP proxy. The conclusion is that, even though the ESG factors can influence financial stability, their effect on default risk is minimal; hence, ESG is not the primary driver of default risk.
