Nexa implements an integrated environmental management system across all active sites, covering the construction, operation, phased closure, and final closure phases, with the aim of preventing, mitigating, controlling, and monitoring environmental impacts. The corporate Environmental Management System (EMS) ensures compliance with internal standards and applicable legislation, including monitoring of legal requirements, internal and external audits, field inspections, and ongoing training.

The Environmental Management Plans (EMP) and Environmental Management Instruments (EMI), approved by regulatory agencies such as SENACE, MINAM, MEM, and ANA, establish guidelines for air quality management, monitoring of surface and groundwater, solid and hazardous waste, effluents, noise, vibrations, biodiversity, wildlife management, natural resource consumption, and control of hazardous substances. The implementation of these plans ensures that environmental impacts are addressed preventively and that corrective measures are applied immediately when necessary.

Operations include programs for the restoration of degraded areas, biodiversity monitoring, control of air emissions, and water resource management, in order to reduce environmental risks and promote sustainability. The Mine Closure Plan ensures the physical, hydrological, and geochemical stability of the components at the end of the operational cycle and is developed progressively.
