eneva < 98 > Water abstraction GRI 303-3 Most of the water consumed comes from the sea and rivers, but there is no direct abstraction from any conflicting watersheds. We follow principles and values focused on awareness and reuse of the resource, strictly complying with the operational and legal requirements set forth in the grant, monitoring the flow captured and performing all the legal analyses of water quality, both at the entrance and at the exit of the operations. We are part of the Mearim River Hydrographic Basin Committee, because there is direct water withdrawal from the Mearim River for the Parnaíba Complex - only 0.5% of the river's flow is used by the plants. In Pecém II, the water is supplied by the Companhia de Gestão de Recursos Hídricos do Ceará, (Cogerh). In the Parnaíba Complex, in specific and transient situations, there is also groundwater abstraction to ensure the operational reliability of our assets. sustainability report 2021 TPP ITAQUI Location of water collection/return: São Marcos Bay, Maranhão.

Despite the higher absolute catchment, our intensity decreased by 8%, reflecting greater efficiency and conscious use of water.
