TheESG Data and Analytical Toolssection of the Official Training Manual (OTM) discusses the evolving landscape of ESG assessment systems. It emphasizes:

“Completeness of coverage varies substantially across ESG tools, with differences in geographic scope, sector coverage, and data frequency. Some tools prioritize disclosure-based indicators, while others integrate estimated data or controversies.”

This statement captures the complexity and fragmentation of ESG analytics—no single platform offers comprehensive global coverage. The manual warns that “investors should evaluate tools based on coverage, data timeliness, and methodological transparency.”

Option A is incorrect since most ESG tools (e.g., MSCI ESG Manager, Refinitiv, Bloomberg ESG) aresubscription-based. Option C is also wrong because methodologies evolve continually to incorporate new standards such as SASB, TCFD, and SFDR.

Thus, the verified correct answer isB.
