Impactos dos desastres ambientais de Mariana e Brumadinho no valor de mercado e nas demonstrações contábeis da empresa Vale.

Abstract

An environmental disaster directly influences not only the community and nature, but also the economic and financial situation of companies, which can alienate investments and capital from third parties, which can culminate in the failure of the companies involved. Thus, the disclosure and measurement of the impact of environmental issues becomes relevant. Based on that, the study aimed to identify the impacts of Mariana and Brumadinho's environmental disasters on the market value and on the company's financial statements. An analysis was carried out in the accounting, economic-financial and social aspects in the period from 2014 to 2020, observing the Standardized Financial Statements made available to the public. The main results pointed out that, regarding the accounting aspects, it was possible to observe a considerable influence on the environmental liabilities related to the Brumadinho disaster. In the years after the accident in Mariana, it was not possible to directly relate the variations to the disaster with what was reported in the explanatory notes evidenced by the company Vale. The economic-financial analysis indicated a probable influence of disasters, mainly in the years of the main events (2015 and 2019). As for Vale's actions, it was noted that, considering longer terms, the impacts on the company's actions after the Mariana disaster were greater than after the disaster that occurred in Brumadinho, even though the event in Mariana occurred in a company that Vale owned 50% of the shares (Samarco) and the Brumadinho disaster occurred in a dam controlled by Vale.
