Seeking ESG Controversy Scores (2021–2024) For S&P 500 Financial Sector Companies

Hi,
I’m doing an academic research project and urgently need ESG controversy scores (not general ESG ratings) for financial sector companies in the S&P 500 from 2021 to 2024 from any reliable source (MSCI, Refinitiv, Sustainalytics, etc.).

Ideally, I need scores that reflect the timing and severity of ESG controversies so I can conduct an event study on their stock price impact. My university (Tunis Business School) doesn’t provide access to these databases, and I’m a student working on a tight (read: nonexistent) budget.

Would appreciate any help, pointers, or sample datasets. Thank you!
