Sustainable Development and Firm Performance
I took a sustainable finance course a few years ago, where we studied the relationship between sustainable firms and profit yields. Findings in this class are confirmed by many other larger scale studies, such as an analysis discussed by the Corporate Governance Institute, that concludes that firms that prioritize Environment, Social and Governance (ESG) factors are proven to be rewarded in the market (Byrne, 2024). It may be green investing in general, or it may be that these firms are consistently more stable and reliable and are therefore attractive to investors. Investors began considering ESG ratings more and more following disasters caused by firm negligence that resulted in large court-ordered payments (e.g., BP's Deepwater Horizon oil spill in 2010) and were followed by a loss of investor confidence, ultimately resulting in a decrease in stock prices. This being said, firms that engage in sustainable development tend to prioritize reliability and sustainable growth and are far less likely to be involved in disasters, such as oil spills, that have extreme negative effects on firm value.
