Secondary ESG data refers to information collected from sources other than official company disclosures, often from external third-party sources.
Primary ESG data: Directly provided by companies in sustainability reports, regulatory filings, or financial statements.
Secondary ESG data: Derived from third-party sources such as news articles, employee reviews, external surveys, or social media analysis.
Why is B correct?
Glassdoor employee satisfaction surveys provide insights into workplace culture, labor rights, and social issues—all key ESG aspects.
This is not direct company disclosure but rather third-party, externally collected data.
Why not A or C?
A (Bloomberg ESG Score) is primary data because Bloomberg compiles ESG disclosures directly from companies.
C (Interview transcript with CFO) is primary data because it comes directly from company leadership.
