Les Déterminants De La Qualité Des Divulgations Non Financières - Le Cas Du Carbon Disclosure Project

Non-financial disclosures are mainly discretionary and, consequently, environmental and social data about firms are incomplete and difficult to assess. In this report, we raise the issue of the quality of these data. A review of the literature first presents the broad range of conclusions reached and highlights the main results. This leads us to question the ability of current data to meet the goals which are expected from them, and to reconsider the relevance of somewhat regulating social and environmental disclosures. Next, we turn to the case of the Carbon Disclosure Project, which frames and promotes voluntary disclosures concerning greenhouse gas emissions. We analyse the determinants of responses and their quality using a sample from the Fortune Global 500. Consistently with prior results, we find that the size of firms influences both participation and the quality of responses, and that firms with more dispersed ownership are more likely to participate. Our findings also point at the weak quality of responses from firms associated with the BRIC group of countries (Brasil, Russia, India and China). Finally, we introduce a model which aims at addressing the main econometric problems encountered and we outline an agenda for future research.
