Identifying greenwashing in corporate‐social responsibility reports using natural‐language processing

A textual analysis of corporate‐social responsibility (CSR) reports reveals that companies engaged in environmental violations report differently from firms with a clean record. The violators issue longer, more positive and more frequent reports to relay environmental content that is more copious but less readable. The violator firms appear to modify their reporting practices right after committing a violation. The findings suggest that culpable firms exploit the current unregulated–unaudited state of CSR reporting as a means of greenwashing and call for institutional change. Our results are robust to a number of industry‐firm characteristics, including board composition, ownership dispersion and international presence.
