Water Resources, Effluent and Waste Management The availability of water quantity and quality is essential for our operations. We use water directly in our oil, gas and derivatives production and processing units; for steam generation; refrigeration; human consumption; among others. As a result, practically all of our activities generate domestic and industrial effluents, such as produced water. Our activities also generate solid waste, which, regardless of the source of generation, can present as complex mixtures of various chemical substances and materials, with a potential risk to health and the environment, in addition to the safety of people and our facilities. Therefore, we undertake efforts to continuously improve the management of water resources, effluents, and waste, considering our value of respect for the life and integrity of our facilities. The search for excellence in the management of our products, throughout their life cycle, includes the environmentally appropriate disposal of solid waste and tailings. We believe, therefore, that the topics are very relevant and strategic for the sustainability of our businesses throughout our chain (upstream and mid/downstream), whether in operations on land or in an offshore environment.
Management of water resources and effluents Our water resource management has as its basic principle to constantly seek the rational use of water, which allows us to ensure the necessary supply for our activities, and to contribute to its conservation (quantity and quality) and availability in the areas influenced by our facilities. In this sense, we seek the adoption of low-intensity water use technologies, the minimization of its use in operations and processes, and the reuse and the identification of alternative sources of supply, always considering the local water availability and the technical-economic and environmental feasibility of the activities. Regarding the effluents generated, we seek to minimize discarded polluting substances, through segregation, treatment and adequate disposal of currents, also observing aspects related to the assimilation capacity of the receiving water bodies and the technicaleconomic feasibility of the measures, with the objective of avoiding or mitigating possible environmental impacts. We use several tools for the management of water resources and effluents, the results of which are monitored by senior management. We develop process standards and specific technical guidelines for these topics, which establish requirements that must be observed and deployed by all our business areas and serve as a reference for our other companies. Regarding the systematization of information, we have a corporate database in which information related to the management of water resources and effluents is recorded, consulted, and processed. It is through this system that we annually carry out our inventory, which, in 2021 included 310 facilities that use water and generate effluents.
