Mariana (MG) Dam Rupture: Changes in Environmental Disclosure for Mining Sector Other Languages

'Purpose of the study': This study analyzes the changes in environmental disclosures in publicly traded mining companies listed on “BMF & BOVESPA” ” stock market after the breakdown of the Mariana dam in 2015. 'Methodology / approach': A content analysis was carried out in the financial statements and sustainability reports of mining companies with shares listed on BMF & BOVESPA between 2014 and 2016. The variable environmental disclosure was divided into seven categories, as proposed by Heflin & Wallace (2011). 'Originality / Relevance': This study is relevant in bringing the discussion on whether environmental disasters, such as the rupture of the Fundão Dam, may increase the information to the investor regarding the potential for another accident within the Brazilian mining sector. He innovates by adapting the model proposed by Heflin & Wallace (2011) to the Brazilian context. nullMain results: The empirical results show that the mining companies surveyed, with environmental liabilities, use Impression Management strategies to divulge their environmental impacts. The strategies used by the companies are the concealment and attribution to external factors, presenting in this way a skewed and selective discourse about their environmental impacts. 'Theoretical / methodological contributions': This study contributes to the literature on environmental disclosure and provides insight into the discussion about environmental management from the perspective of the environmental disclosure of Brazilian mining companies. 'Conclusion': It is concluded that the mining companies surveyed did not increase their environmental disclosure after the dam rupture of the mining company Samarco in 2015.
