The divergence of ratings among ESG providers most likely hampers the ambition of companies to improve their ESG performance. Here’s why:

Mixed Signals:

Companies receive mixed signals from different ESG rating agencies due to the lack of standardization in ESG ratings. This can create confusion and uncertainty about which actions will be valued by the market, making it challenging for companies to prioritize and implement effective ESG strategies .

The inconsistency in ratings can demotivate companies from pursuing ESG improvements if they are unsure which criteria to meet.

Challenges in Empirical Research:

While divergence in ratings poses challenges for empirical research and can affect the reflection of ESG performance in asset prices, the primary issue for companies is the confusion and lack of clear guidance on how to improve their ESG performance effectively .
