Oil is the world's main source of energy. The innumerable benefits it brings to modern society is indisputable. However, this integration and proximity to society, whether in the exploration phase or even in final consumption, has made the sense of responsibility that drives oil operations more latent to all stakeholders. This sense of responsibility is reflected from the extraction process to the decommissioning of the equipment used by the industry, and today we demand greater attention and rigor in complying with the rules of protection to the environment, whether required by national or international standards. Considering the importance of sustainability in the process of decommissioning, whether in the legal or practical part of the process, this paper had the objective of evaluating the sustainability induced by the legislation and the logistic chain for the decommissioning of submarine equipment used in the current oil and gas industry. In order to do so, it was concluded that we have a normative gap to be addressed and a lack of control in the current legislation, but it was verified that the recommendations of decommissioning in Brazil are supported by the current international standards. What is lacking in our context is a standardization of the events that deal with decommissioning, so that it is clear which rules should be applied for each case. The research also showed a lack of transparency among regulators themselves. Also, information that should be available for public domain, for the time being, it is not. The case study carried out at the end of the research showed that it is possible to reuse the materials used to manufacture the equipment that will be decommissioned, as well as estimating the potential market value of the materials taken from the 12 platforms that contemplate Petrobras' decommissioning plan until 2025.
