Environmental, Social, and Governance Information Disclosure: Who Discloses Wins?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT As Environmental, Social, and Governance (ESG) Information Disclosure (ESG‐ID) transitions from voluntary to mandatory disclosure, its drivers and impacts have become focal points of discussion. Existing research, however, lacks integration, which, in turn, has led to fragmented theoretical and practical insights.
