Which of the following is best categorized as a secondary ESG data source?

选项：

A.ESG ratings

B.Company surveys

C.Public documents sourced from the UN Global Compact

解释：

A. Correct because many ESG databases provide secondary ESG data or ratings. These are assessments transformed by a process of scoring or by a formula from a primary data source. Some providers (e.g., Bloomberg) will provide primary data sourced from company reports in an easier or consistent form to digest, along with a secondary rating (e.g., Bloomberg ESG Disclosure score).

B. Incorrect because this is an example of a primary data source. Primary data can be sourced from companies directly via surveys.

C. Incorrect because this is an example of a primary data source. Primary data can be sourced from companies directly via surveys, direct company communication, and company reports, presentations, and public documents. These public documents can be sourced from nonprofit organizations, such as the UN Global Compact.
