Corporate Social Responsibility (CSR)
/The Library of Congress have curated a research guide (Corporate Social Responsibility: Company Profiles & Rankings) that lists organisations which have compiled lists and rankings of companies that are either good or bad in areas such as caring for the environment, sustainability, and diversity. It is very U.S.-centric, but the resources listed are of a high quality, with many of the sites offering further searching/browsing opportunities. Consider this site when you need to find out how a specific company is regarded or ranked.
