Climate Regulation and ESG Disclosure in Maritime Transport
European Financial Management, EarlyView.ABSTRACT This paper investigates whether climate policy signals influence ESG disclosure quality in maritime transport, a capital‐intensive industry responsible for roughly 3% of global CO₂ emissions. Using panel data from 126 listed shipping firms between 2009 and 2023, we construct an author‐based disclosure quality index and treat the IMO's 2018 ...
