Looking for Environment, Social and Governance (ESG) ratings and scores?
Environment, Social and Governance (ESG) ratings have been a popular topic in investing as well as in academic research in recent years.
What are some resources to get one started on this topic? In terms of literature, a good starting point would be a recent 2020 review by Professor Liang Hao - Corporate social responsibility and sustainable finance: A review of the literature as well as Inside the ESG ratings: (Dis)agreement and performance.
Beside the literature, another important resource is the data.
SMU’s Accounting and Finance Research Librarian has prepared a factsheet, FAQ as well as a summary table to compare the ratings, coverage and scope of the subscribed databases on ESG data from different database providers.
