Materiality
GRI 102-42, 102-43, 102-44, 102-46

The content of this Report follows the Materiality Principle established by the IIRC and GRI Standards defined based on topics of major relevance to the mining and smelting sector evaluation, the Sustainability Accounting Standards Board (SASB) guidelines and sectorial benchmarking.

Revised every two years, we decided, for the first time, to make an survey with our external stakeholders in our materiality process. We have combined the results of this survey with 194 complete responses, to the assessment we have also conducted with Nexa’s leadership to deliver at the 12 material topics most relevant to us and to our stakeholders. When defining Nexa’s material topics, we seek to direct the company’s reporting and management considering the context, impacts, risks and opportunities of each topic in the short, medium and long term.

In the external survey, publics were engaged, such as customers, suppliers, public authorities, shareholders, among others, increasing our scope and reflecting in our materiality the issues that are in fact relevant to the stakeholders consulted. Performed according to GRI requirements, which guides companies and institutions to address in their reporting information on topics that reflect the significant economic, environmental and social impacts of the organization and materially influence the assessments and decisions of stakeholders.

The material aspects of sustainability presented throughout the report cover the following subjects: Decommissioning; Ethics and Compliance; Operational Excellence; Water Resources Management; Dam Management; Waste and Tailings Management; Social Management; Climate Change; Plurality; Reputation; Health, Safety and Well-being, and Innovation.

We consider that 2020 was a year of materiality transition, since we are concluding the previous cycle and starting a new process, more robust and with a more strategic view, so that the new materiality matrix can be the main tool for managing the company’s sustainability and ESG (environmental, social and governance) aspects. As part of this transition, long-term goals will be shared in the report for the next cycle. GRI 102-47

Compared to the previous materiality, the Dam Management, Innovation, Ethics and Compliance, Operational Excellence and Reputation topics have been included. The indicators previously monitored under the Human Rights topic were included in the Social Management and Ethics and Compliance topics. GRI 102-49
