However, as there is no single, accepted methodology for calculating ESG ratings, various ratings agencies often have wildly different assessments of the same company, which can prove frustrating. Further complicating the problem is the fact that most data used in ESG ratings is retrospective, making it challenging to foresee how resilient companies are to future risks without the aid of supplemental data analysis.
To gain a clear picture of how ESG factors potentially impact a company’s long-term performance, asset managers should better understand how ESG ratings are derived, focus on the right ESG data providers for the markets they are targeting, and understand what in-house research they need to supplement the external data that is available.
The following ESG rating agencies cover the majority of global large cap companies and are the most commonly used amongst asset managers and investors. All of these ESG ratings are available on the Bloomberg terminal and some are also available to the public on the web:1
These ratings agencies use a combination of company disclosures, publicly available resources and proprietary research. Some providers will use AI technologies to scan the internet for news and developments that might affect the company’s rating.
Currently, there are roughly 30 significant ESG data providers around the world, including the major agencies listed above. However, less than a handful of these have global coverage. In order to tailor to the diverse and growing needs for ESG data in Greater China, a number of boutique data providers are emerging to provide information on companies in the region.

Asset managers can use ESG ratings to help evaluate a company’s value and creditworthiness for equities and fixed income securities respectively.
Equity – On the equity side, a company’s ESG performance is a potential indicator to asset managers and investors of how well it is managing the ESG-related risks it is exposed to. Better management of those risks versus peers may give that firm a competitive advantage and increased profits – this would in turn lower the firm’s overall cost of capital, thereby increasing the valuation of the firm. That valuation plays a critical role in determining whether and to what extent an active asset manager should hold that stock in her portfolio. Passive or index managers can also ESG ratings as a foundation for their stewardship/engagement activities.
Fixed Income - For debt instruments, ESG rating information is used to support creditworthiness assessments, particularly in relation to climate-related risks. The ratings are used to assess how these risks are impacting a company’s overall risk profile, its credit rating and its ability to service debt in the future.
Asset managers and asset owners often ask which rating system(s) are better and why. Somewhat unsatisfactorily, the answer is that “it depends” – on the investment strategy being pursued, the investment process being executed, and the risk/return profile being sought. Our recommendations include the following:
Although ESG ratings are not perfect, they serve an important role in providing a snapshot of a company’s performance to support more sustainable investment decisions. We believe asset managers should make use of this data, as well as applying their own research. It is only through constant engagement and feedback from asset managers that the universe of ESG data and ratings can improve over time.
