Market valuation of greenhouse gas emissions under a mandatory reporting regime: Evidence from the UK

摘要

© 2017 Elsevier Ltd This study provides evidence on the potential benefits of mandatory environmental reporting for listed firms’ market valuation. It takes advantage of recent regulation that requires all listed firms in the UK to report their annual greenhouse gas (GHG) emissions in their annual reports and shows that the magnitude of the negative association between GHG emissions and the market value of listed firms decreased after the introduction of the reporting regulation. This decline is attributed to regulation forestalling shareholders’ negative reflexive reaction toward firms’ carbon disclosures, as proposed by the theoretical work of Unerman and O'Dwyer (2007).
